Transformation: Gin Carrera to Gin Carrera+ (Plus): Part 3



In the basement sits a Gin Carrera+, its lines swapped over two weeks previous. The conditions that day allowed only for a short kiting session. Inaugural flight is still in the queue.

Today: a sunny Saturday morning with questionable winds - northwest, 15+ kts. A opportunity to head for the training hill @ Diefenbaker Park and try my hand at foot launching in rotor. The recently completed South Fraser Perim Road makes short work of the drive, allowing for a bypass of Burquitlam and New West. All in all, a 40 minute drive in non existent traffic.

Arrive to find the park empty - I gather iPG is none too keen to have students out in this. Wouldn't blame them as the conditions are leaning towards a plucked and dragged sort of day for newbs.

7AM on a summer Saturday, this place is typically filled with students and wings. But not today.

Setting up on the southern slope facing into the park bowl, I quickly clip in during a lull. A quick duck under to face the wing and a swipe of the brakes.

The rustle of leaves from the trees to the N/W followed by a rapidly building sway in the trees down the road to my right (west) signals an approaching gust. Gloved hands fumble to get at the C's - the risers miniscule width coupled with the new lines frustrate my efforts.

The gust builds, snatching the wing.

Pulling in the C risers, the tail is kept firmly planted. Looks like the new riser design does the job.

I use the dying wind to work the wing quickly into a wall and let it settle back onto the ground.


And wait...

And wait...

Another gust begins, but more west. There is enough to bring the wing up, turn, and run more or less across slope.


And wack!

The left tip falls victim to the rotor being formed off of the trees backstopping the main slope of the hill.

Kill the wing, ball it up, trudge back up.

A trio of attempts follow before calling it a day. I have one question answered - can I ground handle (thus launch) it in strong conditions?

Yes.

But how will it handle in light to nil conditions?

A question that will have to wait for the FlyBC training hill tomorrow morning.

Transformation: Gin Carrera to Gin Carrera+ (Plus)

Finally!

After two months, the line set has arrived.

When I first demo'd the Gin Carrera, I remarked on the inability to A+C's the wing during launch due to a rather unique riser configuration. The C3 line is mounted to a floating maillon between the main B and C attachment points. The webbing upon which this maillon rides significantly limits the C riser range of motion. The updated Carrera+ riser is expected to help address this short coming by lowering the rear attachment of the webbing strap.

The other thing that stood out was the 'floppy' wing tips. The brake fan layout on the first generation Carrera would engage the centre portion of the trailing edge well ahead of the tips. The byproduct of this configuration is a reduced 'feeling' for an impending collapse short of riding somewhat deep into the brake range. The new line layout on the Carrera+ is expected to 'slow' the tips and engage the trailing edge in a more even manner.

The upgrade kit itself consists of 50 lines (for XS through to M) or 56 lines (for L and XL), an instruction set, a pair of new risers, a new certification/serial number label, packing bag tab, and a '+' sticker to affix to the right of the 'Carrera' label on the wing tip.

The instructions are a single double sided page:



The line set is organized into a collection of daisy chains, grouped by riser and by tier.

I set out to break the chains down and subgroup by pairs of individual lines.

Brake lines mid tier. Each pair (L and R) is placed in a single marked baggie.

Once all of the pairs are divided, its time to label the old lines that are to be replaced. As the instructions are not available online, I went overkill and created a label for every line, unsure which would be flagged for replacement.

Line labels.
Wing laid out in the backyard.

A check of the instructions to confirm which line is next.

Crack open the maillon, slip the line free, follow it to the attachment, un-hitch.

Place the tagged old line in a large baggie and extract the new line from its individual baggie. Check the tag holding the line pair to confirm the index (there is a slight inconsistency in how the lines are labeled on the instructions and on their tags - but it is easy to deduce what goes where). 

Follow the new line end to end, being sure to follow the instructions to attach the thicker sheath portion of the bottom most lines to the bottom of the mid cascade.

Re-attach. Rinse and repeat for other lines. When done, place back on old risers in same order.

I will do the riser swap at the dealers, as he has a rigging loft when I can also check each line end to end before taking for a spin kiting.

Thus far, both sides:
  • A+Bs -> 1.5 hours
  • Brakes -> 40 mins.

Paragliding 103: HPAC Novice/P2 vs. Asymmetric Collapses

Asymmetric Collapse

The asymmetric collapse, an inevitability of learning to fly in thermic air. We learn to first mitigate and then prevent them by flying in increasingly active air, preferably under instruction.

Mitigation can come by way of active weight shift and braking technique. The ultimate goal is collision avoidance, be it with the ground, terrain, or other pilots.

Another means of mitigation is wing selection (passive safety). A lower EN/LTF rated wing can help reduce the aftermath of the collapse. An instructor is the best place to start with deciding which wing is best suited to the pilot. That said, the first steps we take as a pilot-in-command is making and accepting responsibility for own decisions. The more information the new pilot has, the better the decision they can make.

The basic certification system (EN/LTF) is not perfect, as per Divide 'EN', Conquer. But the certification system is continually evolving. Part of this evolution is the trial testing of wings by the DHV using a data logger and documenting the post collapse behaviour beyond a simple change of direction/pitch.

DHV Safety Class

The core of the DHV Safety Class is a trio of safety ratings per wing: symmetric collapse, asymmetric collapse, and spiral dive. In addition, notes are provided on altitude loss, G forces experienced, cravat and cascade tendencies. It is these notes that are of interest.

Below are the DHV Safety Class Notes on unaccelerated asymmetric collapses for common paragliders used in the Fraser Valley (Vancouver) for student and novice pilots:

The source for these values and notes can be found under the DHV Safety Test webpage.

In addition, the suitability for training and manufacturer notes regarding the target pilot are included to give a more complete picture. This data was pulled from the manufacturer webpage and user manuals.

Wing Made/Model  Height Loss Pitch Angle G Force Training Suitable  DHV Notes Manufacturer Notes
Skywalk Mescal 4 20 - 29 m -60 degrees 2.4G Yes Massive collapses and maximum deformations usually recover with little diving and course change. Suitable for beginners on the training hill, the MESCAL4 also offers lasting satisfaction for ambitious hobby pilots for their first XC flying experiences.
Icaro Cyber TE 30 - 39 m -65 degrees 2.3G Yes Relative moderate reactions, moderate dynamics Beginners who are looking for a fun, but performant and fast glider, that—nevertheless—still is gentle and easy to fly, will find a good companion in the new Cyber TE.
Ozone Mojo 4 40 - 49 m -65 degrees 2.3G Yes Greater height loss and course change angles than other [...] gliders. The Mojo 5 is designed for new pilots. First and foremost it is a safe, fun, and easy high-performance wing suitable for students in training but ideal for the newly qualified.


Wing Made/Model  Height Loss Pitch Angle G Force Training Suitable DHV Notes Manufacturer Notes
Ozone Buzz Z4 30 - 39 m -60 degrees 2.3G N/A* Moderate dynamics, height loss < 40m. Maximum collapses result in large pitch forward dives and occasional opposing collapses, but without course changes.  The Buzz Z4 is an ideal choice for pilots who fly approximately 30-50 hours per year [...] .
Skywalk Tequila 4 40 - 49 m -75 degrees 2.9G Yes Difficult to collapse to measurement field limits. Marked rotation with dive angles of up to 75° for large collapses. Opposing collapses observed with occasional cravats and course changes.  The T4 is quite forgiving, making it the right choice for talented beginners.
Icaro Instinct TE 40 - 49 m -75 degrees 2.9G Yes Without using special collapse techniques the wing collapses very steeply and has high rotation and pitching dynamics, resulting in opposing collapses and cravats on both wingtips.  Since it performs at a very high level, but is also very pleasant and well-behaving at the same time, the Instinct TE is the perfect glider for all pilots who want to feel comfortable in the air.
Icaro Wildcat TE 40 - 49 m > -75 degrees 2.6G No Height loss is average for its class, but reactions are very dynamic, dive forward angles are severe and course changes are rapid.
The canopy folds steeply, creating a lot of resistance and turns abruptly and dives forward steeply. Total height loss was average for the class. Generally the canopy shows a tendency to dive forward steeply which often leads to cascades and cravats.  
Recommended flight experience: 20 - 30 flying hours per year.
Gin Atlas 50 - 59 m -60 degrees 2.3G N/A* Relatively low dynamics (pitching, G-forces, sink velocity) for its class, but delayed recovery resulting in higher height and course changes.

In some cases, recovery had to be aided with a little pilot input.
The Atlas is suitable for beginning to intermediate pilots.

* There is no clear indication regarding suitability (or lack there of) for training. Consult your instructor.

Side note: notice any differences between the DHV and Manufacturer Notes?

The HPAC Novice/P-2

The current Hang Gliding/Paragliding Association of Canada (HPAC) requirement to be awarded a Novice/P-2 rating includes the following prerequisites:

B. Prerequisites

  • Paragliding P1 Beginner Rating
  • Thermal Endorsement or the Coastal/Ridge Endorsement

 The Thermal Endorsement includes the following:
  • Demonstrates proper directional control and correction of full (i.e. 50% of the wing span) asymmetric collapses.

Anyone flying in the Fraser Valley will receive their Novice/P-2 with the Thermal Endorsement (due the lack of a consistent Coastal/Ridge Soaring Site). 

Under the current HPAC requirements, the Novice/P-2 candidate who satisfies the Thermal Endorsement will have demonstrated the proper response to a 50% asymmetric collapse. 

Re-read the above descriptions of asymmetric collapse behaviour and ask which wing would you want to be on with less than 25 flights and asked to demonstrate the 'proper directional control and correction of full (i.e. 50% of wing span) asymmetric collapses'. Demonstrating a response means experiencing the collapse to then demonstrate the proper response.

I suspect if this requirement was fully enforced by HPAC, we would see very few students on EN B wings.

It is better to have a wing you can grow out of than one you need to grow into.

Happy Sky Birthday* to me!

June 26, 1999.
Mile High Parachuting.
Jump 1.

A rather warm sunny Saturday in Arnprior, Ontario.

Nervous energy moves throughout a group of lads of varying origins, ages, and occupations.  They have congregated at this small airport with one goal in mind - to jump solo out of an airplane for the first time.

The skittish herd was greated by a trio of instructors ('Turtle', Eldon, and Cyr) and ushered into a classroom to learn a pair of mantas needed to complete a IAD (Instructor Assisted Deployment) jump. The first being the dynamic exit - "Have you got my pilot chute, left foot, left hand, right root, wingtip. Arch-thousand. Two-thousand. Three-thousand. Four-thousand. Check-thousand." The second being a cutaway and reserve deployment - "Look. Reach. Pull. Look. Reach. Pull.".

Throughout the morning of lessons we were prompted to repeat these mantras, louder and louder. Drilling home these distilled steps. Nail these, let gravity do its thing, and everything will be ok.

Following the classroom was the hands on training: chucking ourselves from the mockup of the Cessna C-182 onto a thick mat, learning the art of PLF, and the (soon to be dreaded) hanging harness...

We were walked through the process of identifying if a canopy could be landed, and if not, how to perform the physical actions that paired with the reserve deployment mantra. While hanging in a retired old skydiving harness, a picture of a canopy in some form of (non-)malfunction would be placed over  our head.  If judged to be a malfunction, we would be coached through the process of cutting away and deploying the reserve. Even if the canopy was land-able and we cut away, we were praised for making ultimately the right decision (if in doubt, cutaway).

After the first handful of passes, Cyr (a former Canadian Airborne Regiment NCM) took over. The tranquility of this sleepy country airport was shattered with a cacophony of yelling and shaking.

The first to fall victim went complete deer in headlights, plummeting to his virtual death.

Calm.

Repeat the cutaway process in a slow and controlled manner.

Success.

Set volume back to 10.

Success.

The seeds of stress inoculation are taking root.

My turn comes and goes like the others. One of mine was a good canopy chop due to line twists. When in doubt ...

Spring, 2002.
Skydive Chicago.
Jump 115.

Stoked after a successful dive out, chase and dock on a 4 way formation, I deploy typically high at 3500 feet.

Line twists during the opening. No big deal.

Then a turn and dive. I'm on my back and the wind noise cranks right back up. Big deal.

Back to that day with Cyr, instinct kicks in and I'm under a reserve.

Too this day, I credit the reserve pack job of the SDC rigger and the training at the hands of Cyr with saving my life. MileHigh drilled home the need to completely banish indecision and aggressively execute the needed corrective action in a stressful training environment. They had this in place before we ever set foot in the plane.

Today.
Vancouver.
A few hundred jumps more.

So what does this have to do with a paragliding blog?

I ask, how many paragliding schools (or national associations for that matter) require reserve training before high mountain flights?

I suspect you will quickly discover the same as I -> nada. Excuses abound.

Incidents occur - even during student training. Not having the foreknowledge to properly execute a reserve deployment greatly reduces the ability to respond.

Reserve training needs to be done in a recent, relevant, and realistic manner. At the very least that means a hanging harness with induced stress. Before feet leave the mountain.

It might save your life and enable you to share many of your own PG Sky Birthdays to come.

* Sky Birthday - a skydiving term for the day of your first solo jump. The day you were born a skydiver.

Paragliding Economics 101A: Shopping Around (First Paraglider Purchase).

Looking at lessons, trying to sort out the true costs.

No rental option, local used market is dried up (there is an ebb and flow to used wing availability - very dependant on time of year).

Guess a new wing it is.

If you are part of the rare 1% who has reigned in impulse and taken a step back to consider the true costs - you're likely wondering how to best save some coin on equipment purchase. 

The majority of the worlds wings are fabricated in a small number of factories that cater to multiple brands (a secret manufacturers don't make very public) and are made from a very small collection of fabrics. The result -> production costs are relatively similar.

In addition - R&D, administration, and marketing typically scale. Larger manufacturers pour more into marketing (sponsoring competition teams and factory pilots), have in house designers, and employ test pilots. Smaller shops outsource the entire design process and limit marketing to very specific regions/segments. 

What does this all mean?  

Commoditization.

A wing in EN class X should cost Y no matter the brand. A price above this is either result of inefficiency or the padding of margin somewhere between you and the manufacturer. The former will die due to decreasing market share, the latter will perish with an informed customer.

What can you do?

Become informed. Window shop around. This can be a touchy subject as it will eat into a schools margin. A *pre-authorized* purchase outside the school is sometimes offered as an unspoken option for an 'uncorking fee'  - typically around $500. It will not hurt to ask up front before paying for lessons, if I want to buy a different brand than what you carry, what is the additional cost? If nothing else, it could pressure the school dealer to price match if they wish to maintain market share.

How much could you save?

Pricing options for low end EN-B (a common first wing here) plus harness and reserve in the Vancouver market:

Equipment Dealer A Dealer B Dealer C
Wing $3900 $3500 $4000
Harness (with back protection) $900 $650 $1100
Medium Reserve $660 $700* $1000

* I had to query the reserve price, as none was published.

The right combination of the above can net over $1200 in savings.The catch is the need to negotiate. A smart dealer will realize a customer who feels they are getting a good deal will become a repeat customer.

In the end the right questions cost you nothing and can save you alot.

Back in the saddle: Part 2 (with the Skywalk RangeAir)

The wind sock goes from limp to a south, to a southwest, back to limp. The wing 'breathes' with the rise (the nose rising, A's tensioning ) and fall of the cycles (nose rolling over, A's going slack).

A cycle presents itself - going from a south to straight in southwest. Pull up and the high AR (aspect ratio) of the wing makes itself felt. Half the wing orients south, the other half more west.

Herding wingtips.

Having experienced this a few times while kiting the Delta2, I ease off the right side brake and let the lagging side 'snap' back into alignment. Kite for a second to let the wing settle, turn, and kite another second to be sure everything is good to go (an instructor from Germany mentioned letting the wing settle a second after it reaches the apex).

The cycle ebbs as I start the run. Airborne, touchdown, airborne, touchdown, airborne and away.

Long runways and weak days go hand in hand.

Two tries and I'm in the pod of the Skywalk RangeAir. The RangeAir is an extra light airbag XC harness. I have been a huge fan of airbag based back protection after watching a low airtime pilot spin a wing at tree top height, have it surge, pendulum him underneath then drop him hard. Running over, I fully expected to find a corpse. Instead the pilot was standing up and brushing himself off. The airbag harness absorbed the brunt of the fall.

The catch to an airbag system is that it needs to be inflated (by ram air) for it to work. Maybe not particularly well suited to those who are likely to suffer a drop launching such as a student who lacks the kiting skill to manage a wing or a comp pilot who doesn't have the luxury of being picky about the cycle they launch in. But for those in the middle, it is a viable option if weight and pack volume are limited - hike and fly pilots along with the globetrotting crowd come to mind.

As for the effectiveness of airbags - give this spreadsheet a gander. The lower the G force value listed (in column H), the lower the impact force passed onto the pilot. 'Schaumstoff' is foam based back protection (as opposed to airbag).

Back to the RangeAir, comments sent back to the dealer include:

A few observations - the weight and pack volume phenomenal. I can fit the harness + reserve in the Gin concertina bag with the Carrera. The reduction allowed me to drop to a 90L pack (from a 130L) with the possibility of dropping to a 70L. The loss in overall weight has me on the cusp of downsizing to a small wing.

Setup is a bit fiddly. I found the best way to accommodate is leave everything attached and loosen the shoulder straps for step in/out. Extra attention to the speedbag closing lines is needed in this case during donning - they like to pop loose.

The speedbag is very easy to get into post launch - I don't need my foot leash like I do with the Impress 3.

The chest strap appears to be non adjustable. I found out how much wider I normally run the Impress 3 in comparison when I near line twisted myself up leaning in aggressively on entry to a tight core.

I am leaning towards saying the Range Air provides more feedback vs. the Impress 3 but need more airtime to be sure.

Two additional features of note - the reserve is front mounted, which satisfies the growing comp requirement that the reserve be reachable by either hand. The front mount also eliminates the possibility that pilot weight in a hammock harness (as opposed to those with a seat board) will interfere with reserve extraction. There is also the matter of an underseat reserve potentially placing a non compressible perch between the pilot and the ground. The first thing that will hit may well be that  un-deployed reserve, prevent the remainder of the body from absorbing any impact - driving the entire impact force up into the spine. Something to think about - is the underseat reserve under your spine or your upper legs?

The second is the flight deck/front mount reserve container that is held in place by attaching to the chest strap. This helps eliminate the possibility of launching without having the leg straps done up. I had crossed paths with a fellow Impress3 owner who had launched with the flight deck secured but not the leg straps. The small snap shackle held them in long enough to get into the harness, but the shackle design would not have held them long if they could not hook their feet into the speed bag (based on comments from a harness designer back in 2012).

Back to the flight.

The trusty spine.

After a few beats back and forth, there isn't much out here yet. I try my goto trigger, the spine to the north. There is some lift, but not much. Time to push out.

The vario shows a south wind @ 8kph (2 m/s). Climbs are also 2 m/s. Add that to a 1 m/s sink.

Quick mental math time: 2 m/s horizontal vs. 3 m/s vertical. Move upwind, but not much today.

And I find it, 5 seconds of climb along a southerly course. A turn right and I fall out the side. Get it around quick then begin to widen the turn. More chirps from the vario. Tighten it up and we have a core.

Bring it around. Bring it around.


399 m.
400 m.
401 m.
401 m.
400 m.

An inversion establishing or did I just lose the core altogether?

Widening the turn again, looking for a way to keep climbing.

The Carrera starts 'sniffing'/edging right. I align the wing with it and feel myself being sucked in.

Another climb, this one breaks through and gets me to 460m, but has me pretty far north. Zero chance of making Riverside, still a chance of making the Ranch. Time to push out, keeping some margin for error on a day the winds are forecast to climb quite a bit. Not a lot to be found, again bouncing off an invisible ceiling around 400 m.

Not much from the farm buildings today.

Eventually, gravity claims both the wing and I as we set down at the Ranch.


The afternoon is punctuated with a bit of kiting in the growing valley winds. Attempts at A+C'ng the Carrera is met with frustration as the wing repeatedly tries to horseshoe. Hopefully the C+ addresses this, as this is my go to technique for stronger mid afternoon conditions.

No point in fretting about it until I have the new line set installed.

Otherwise a good day to be back in the saddle.



Back in the saddle: Part 1

A year and a half of doctors, specialists, insurance intermediaries, and drug coordinators to finally be able to have this view:


Health was slowly but surely worsening, bringing flying to a halt at the end of last season (the season in itself became more or less a write off after France). A brief respite was offered last Fall with one drug but with side effects it was not destined to become a long term solution.

But then hope. A drug regimen that could bring back a quality of life not known since mid 2013. There are risks (some potentially fatal), but what is the point to quantity of life if there is no quality. So here I am, plugged into an IV and getting pumped full of chemicals with one plan in mind - getting back into the air.

Cut to the following morning. FlyBC is the immediate target, the launch on Mt.Woodside is the ultimate goal. Upon arrival, things are little slow starting - the crew are awaiting students and tandems alike. It doesn't take for Jim and I to cross paths. Jim passes on that the Carrera+ line set kit should be in within a week. Aside from a few quirks - the initial brake travel deflects the centre trailing edge while leaving the tips unaffected (making it difficult to sense collapses without going well into the brakes) along the extremely short amount of play between the B+C risers (making A+C launches in strong conditions tricky) - I'd be singing praises to the moon about this wing with the feedback, handling and performance it has for a B. That said, rumblings from the interwebz hint that the kit might have swung the pendulum too far the other way - taming the tiger to the point of making it a house cat. For a few hundred dollars, I'm willing to take the chance.

Lounging in the barn, eyeing the launch webcam.

Looks like Degas is already up top and launching a pair of self landing students. The early days of being under instruction and having to be up at 5AM. Don't worry chaps - it gets easier (both with respect to flying and not having to be up before sunrise).

Then a 'Here!'

A dark mass hurtles my way.

A t-shirt. A new load of FlyBC branded wear just arrived. 'Shut up and Fly' remarks the back. Be in the moment, not a detached bystander I take it to mean. Very fitting in our social media age where posting about the event tends to trump the experience. Yes, I see the irony.

People filter in, the van fills, and we're off.

At launch, nary a wind this morning.

Oh well.

Tandems first, students second, then moi. I'm not being polite, just pragmatic. Students make good thermal markers - send enough of them out, they are sure to find something.

A few good launches, a few amazing launches (funny how you can spot the gifted ones fairly early) and Jim heads off to start collecting everyone at the LZ.

I hear a truck making its way up the road. This early in the day, odds are another school.

I like to think of schools as coming from one of two trains of thought - the German or the French.

The German school will lay the unattached wing out in the centre of launch and check every individual line from karabiner to attachment. Then they will clip in, perform their 15th preflight check, and wait. And wait. And wait. The elusive perfect cycle is out there.

The French on the other hand will preflight the harness and wing before packing it away. Then pull everything out, still attached, don the kit at the back of launch, preflight it again, and carry their rosetted wing out. The mass is tossed mid launch. The wind is used to work the wing into shape. The wing is then pulled over head, kited, and checked. If everything looks ok, they are gone.

Why do I mention this -> If a French school pilot gets in front of you - its no big deal, they will be in the air in a minute or less. If a German school pilot gets in front, break out a novel because its gonna be a while. The German school pilots are more commonly known in these parts as launch potatoes (I admit I am a reforming launch potato).

I fear this school might be of the German mindset and quickly get kit ready. The trucks pull into the parking lot. A FJ? I recognize it as belonging to Martina. Sigh of relief. No launch potatoes.

An entourage follows Martina up. Friends/family of a neighbour of hers who is going tandem.

No pressure. You only have your mentor and entourage watching.

A lesson in why kiting is an important part of launching soon follows.

This is why we can't have nice things.

Chatting with a flying counterpart a week or so ago, they mentioned they wanted to try flying Austria one day.

"You can't."

"What do you mean?"

"HPAC paraglider ratings are not recognized in Austria, IPPI card or not."

"Huh?"

"It appears our licensing system wasn't judged to be up to par. The Brits, Swedes, Germans all ok. Us, not so much."


A discussion followed suit on how best to bring this to the attention of HPAC and see if there is a way to address. The rating system went through a recent overhaul and surely would match up against the best Europe has to offer (at least thats what we were lead to believe).

Then a few days later, a posting by one of the HPAC SIs (a Senior Instructor - the folk who set the standards for our ratings):


I think the Austrians are onto something.

Purchasing a used paraglider.

By this point, you've gotten a sense that I am very much in favour of finding the most cost effective means possible to get and remain in paragliding (and still retain a high degree of safety).

I've outlined how you can go about evaluating your local schools to find the true 'soup to nuts' cost of getting a license with Paragliding Economics 102: Lessons.

I've also outlined why with your first wing you should favour a used paraglider over new and rental over used with Paragliding Economics 101: First Wing Purchase.

But lets say your local school does not offer wing rental? Now what? Assuming suitability (as discussed with your instructor) and availability, into the 'pre-owned' bazaar we venture.

Two Simple Rules

Rule 1: The seller needs my money more than I need their wing. 

This is my variant of the age old 'there is no such thing as savers remorse'. I remind myself of this before any interaction with someone looking to sell. Putting myself in this frame of mind helps keep me objective and enables me to easily walk away - a deal that fails leaves me with money everyone wants and the seller with a wing few people want.

Rule 2: Trust no data that is not readily measurable. 

Launched off grass, accordion packed, no SIV, closet stored. None of these statements mean anything to me as I can't readily verify them. As a buyer I want to know four things - the 'Four Ps' - price, pilot, pics and porosity.

The Four Ps

Price - Price is self explanatory.

Pilot - I want to know who has been flying this wing. This info allows me look up the flight logs in Leonardo and XContest. I can also look up videos on YouTube and Vimeo. I can even look the pilot up in ParaglidingForum.com. Sounds creepy? I don't think so. This is how I determine if they are being honest with me - compare the description of the wing with their digital paragliding foot print. I have seen cases where a pilot selling a wing claimed it had only X hours but was bragging a month earlier on Paragliding Forum how they had clocked 2 times X on the wing that summer. Likewise with track logs and videos. Only grass launched, how about those tracks in Turkey? No SIV, funny that video of acro over Annecy. If there is any inconsistency, remember Rule #1 and walk away.

Pics - Pictures of the wing are always nice, but what I am after is a pic of the manufacturer label. This will have the Make, Model, EN rating, Serial Number (S/N) and Date of Manufacture (DOM). With the DOM I apply my previously suggested depreciation of 20% per year and check it against the sale price. Also, if there is any doubt in the legitimacy of the sale, I ask that a sticky note be placed in the photo of the manufacturer label with my name and date. I would reserve the use of the sticky to be a condition of final sale after price is finalized and not something to push for right away.

Porosity - I will not touch a used wing that has not had a proper test done by a porosity meter. I would also ask for a photo of the test result.  My minimum is leading and trailing edge centre top cell - it is the part most likely to be smacked nose first into the ground on landing and dragged tail last during take off. I suggest researching the relationship of porosity to wing lifespan, there are a few graphs floating about. One note of caution - a wing can retain porosity well after the fabric has passed its useful life - you will frequently see this with wings from the last decade flown only one season and closet dumped. The porosity will be high, but the fabric will have the strength of tissue paper. Another reason to ask for a pic of the manufacturer label. I personally will not consider a wing more than a few years old because of this.

Summing it up

With a little 'leg work' and an objective mind, there is quite a bit of savings to be had by going into the secondary paraglider market rather than purchasing new outright. If you keep the Two Rules and Four Ps in your kit while evaluating options, you stand a much better chance of walking away with a deal you are happy with as opposed to an unexpected surprise a season or so down the road.

Sled run for one, sled run for all.

Day two with my sheep in wolfs clothing (the recently acquired Gin Carrera Medium in Apple).

The atmospheric sounding for the day is looking promising with moderate lift to above launch height and an ever increasing prefrontal inflow. Get out early and stay up all day is the plan. Too bad reality doesn't always mimic the forecast.

Arriving at the FlyBC Ranch, I see a number of cars parked about but zero activity. Maybe everyone has already headed up the hill?

A quick peek through the spyglass reveals the Russian collective up on launch, but no sign of Jim or crew.  A few wings eventually launch and make their way down to the Riverside LZ. From the direct route they take I suspect lift is as elusive as ever today.

Half an hour passes and a truck pulls up carrying one of our 'long lost brethren', Robin, who has been pulled away by the real world for the last season and a half.  We catch up on how things have been and Robin provides some suggestions on shows to watch to help kill time as the long white cloud of winter dampens flying. Gary and (the other) Martin soon arrive and we make our way up to launch.

Up top appear a few other faces we rarely see these days - Mia and (the original) Martin. Must be a special event bringing everyone out.

And that there is - an ash scattering.

One of the local landowners, Joe, who had been a big part of the flying community passed some time ago and his family wanted him to enjoy one last flight. It would be another few hours before that flight was due to occur, but folk were making their way up to launch and getting a first sled run in before the main contingent arrived.

The first flight off was uneventful aside from the nuisance of the brake line 'ball' on the right toggle getting fished through a pair of twisted C lines. Basic preflight failure - not following the line from the toggle to the 'swivel' after an abort. Not impressed with the loss of the flight, I make a point of swinging further south over the ranch to put myself in clear view of anyone in the parking lot - hoping someone might look up and hang around a few mins while I pack up.

The gambit pays off as Jim pulls the 'bus' around into the LZ and a few students hop out to give me a hand quickly packing up the wing.

Round 2.

We arrive to find a decent size crowd on launch just as the Joe's ash flight is about to take off. They are away without incident and head south-ish. Another tandem quickly follows suit (I suspect a second family member). It is certainly a perfect day to see Joe off - not a cloud in the sky and silky smooth air.

My flight was another of non drama - smooth inflow, little to no lift. A textbook student first flight day.

Landing, I figure I am done for the day and have the car packed up. Robin lands and starts discussing with Martin about the possibility of time for yet another go at it.

6.2 aspect ratio in an EN B, who would have thought?

Round 3.

The cycles are dying off in the setting sun. The Carrera is as easy a wing to forward launch as any and I am away knowing this will be yet another top to bottom. Might as well make the best of it and it's varying degrees of speed bar all the way down.

An amazing weekend to break in a new wing, catch up with old friends, make new ones and, most importantly, to send one of our 'family' off.

If the season ended here - it would be on a perfect note.

*contented sigh*

Take some Gin (Carrera), add some Apple, shake (Part 2).

...

not even packed up and the Atlas pulls up in the landing field. The query from the cab, 'heading back up?'

That is an affirmative, Ghostrider.

Back on top of the mountain and every one is milling about, not a wing in the air.

Curious.

A gust comes through rustling the trees and ... blowing downhill. Ah, so ka.

An hour later, having gotten my fill of jawboning with local and student alike I realize that we are starting to see marked lulls in the downhill flow of wind. There is going to be rotor at some point away from the hill, but the sound of the wind in the trees hints at peak speeds less than 20 kph. Definitely choppy, but manageable.

I recall a piece of advice from Chris over the summer regarding boundaries and a shrinking flight envelope. If we never test our comfort zone, the conditions within which we are willing to fly will continually shrink until even the tamest of conditions will be perceived to be beyond our ability. In other words, from time to time we have to be willing to go to where there be dragons.

Begin pre-launch montage.

And so the cycle begins of waiting for the elusive lull, hoping the mountain doesn't go completely katabatic before I can get away.

I feel the slightest hint of uphill wind, the flag at the bottom showing wind coming in, the sock beside me limp. Its enough and I am off.

3...2...1... cue 'Highway to the Rotor Zone'.

I drift rapidly to the left and turn quickly right 90 degrees to face into the wind coming over the ridge to the north. The aggregation of the wind being driven up and over that ridge line has me parked in its lee. I am not entirely sure how far this compression extends, so the thought of a straight downwind run leaves me iffy with the river in that line of flight. I feel my best chance is cross wind it and face west again. My active flying skills gets their first real test since France, with the wing rolling, yawing,  and pitching about in the turbulent churn. It is under these conditions I get a better sense of the pitch stability of the Carrera. On the Delta2 I would have my work cut out for me with the wing reacting to the gusts in a series of sharp pitching motions. The Carrera remained more or less overhead, freeing some mental effort from having to be hyper vigilant in trying to prevent a full frontal via an errant gust. The roll on the other hand demanded more attention, with one cross wind gust announcing itself with a rapid twacking of the fabric in the speed bag of the pod followed by my losing the left quarter or so of the wing.

A minute of riding the chop and I am in dead calm air. Jim had chimed in on the radio suggesting pushing further south towards the Riverside LZ as opposed to my drive west, pointing out that the wind would die off quickly as I move further downwind from the northern ridge. In retrospect, it would have provided an increased chance for success over my eventual route towards the Ranch LZ.

Lesson learned.

After the mountain tried its hand at shaking up a Gin/Apple martini I feel that one could sum the wing up as "feels like a 'C', recovers like a 'B'".







Saturday, 20 September 2014

Take some Gin (Carrera), add some Apple, shake (Part 1).

Tuesday, a peek in the inbox reveals, "Still interested in trading in your Delta 2?".

Jim has a potential buyer looking for a preowned Ozone Delta 2 Large, I'm looking to downsize, and the demo model Gin Carrera M is up for sale.

We might just have the makings for a deal.

By end of day we certainly do as I am lighter a Delta 2 plus some cash and heavier one Gin Carrera in apple.

Courtesy of Gin Gliders.
The weight loss that drove the downsizing had been root caused by the specialist the day prior (a genetic conspiracy it would appear) and meds prescribed to get it and a plethora of other symptoms under control (one of the more notable being nausea that would take hold in less than 20 mins from the time of launch).

Saturday morning. While the side effects of the meds are still a bit of a nuisance, I am starting to feel better than I have been in several months.

Only one way to celebrate this fortunate turn of events, pile the kit into the car and bee line for the hill.

Upon arrival, the LZ is virtual ghost town with Jim having taken the students to the training hill pending the establishment of the afternoon inflow. Knowing there might be an hour plus wait I wander the Ranch and chance upon a pair of pilots waiting for a ride, chatting them up in sequence to help kill the time.

The beep beep beep of a Nissan Atlas backing up heralds 'go' time and we all pile into the van for the first run of the day. The skinny on the Line group for the local club hinted that most folk would be up in Pemberton thus leaving us an uncrowded hill for what might be the last weekend of summer.

The crew is a mixture of first time and low air time pilots, plus moi. The nervous energy of the first timers, as they come to grips with the magnitude of what they are about to do and the sense of empowerment that will surely follow, leaves me with both a smile and sense of envy. How many of us on those first few rides up the mountain were not thinking at some point, "why am I doing this?", only to have any and all doubt disappear within seconds of landing?

Left to my own thoughts - how is my stomach going to handle this? The wing is smaller than my last and despite the EN-B rating, it is much more talkative (reactive to turbulence). Much like the first timers, I need to cast doubt aside and simply trust that it is going to be fine.

At the top we find waiting for us (the other) Martin and a pair of ladies that typically fly Bridal Falls on the south side of the valley. With the sun inching lower on the horizon each day, north facing Bridal is finding itself more and more in shade thereby driving the regulars to south facing Woodside. But even with this trio added to our ranks, Woodside is far from becoming a beehive of activity today.

The femme fatale duo launch first, followed by myself. Getting settled into the swing of things takes longer than normal as I try to align how I would fly the Delta 2 with the handling of the Carrera. It doesn't take long to realize that I need to let the wing do its thing and more or less just 'shut up and listen'.

Allowing the wing to sniff out the sporadic collection of 0.1 and 0.2 m/s climbs, I again have Kelly's advice playing in my head about mirroring the air but keeping energy in the carve. The wing turns in much quicker than the Delta2 and yet I find it more reluctant to dive if I am bit heavy handed on the initial turn in. Following what appear to be a trio of buzzards, I claw and scratch my way back up to launch height. By this point I am half an hour into the flight and my stomach is handling things remarkably well. Two more pilots have since launched and all have or are in the midst of landing.

Then the -2.4 m/s flush.

No matter where I go, the mountain is singing some Celine Dion track whilst I am being drilled to the oceans floor.

To the LZ it is. Nary a climb on the way out, but it matters not as I arrive with height to spare.

Thus ends what is easily my best flight since the last day in France at St.Vincent.

There is hope.

Flying Fast Forward 2014

The 2014 season is well under way with:

The Ozone Chabre Open in Laragne, France.

XC Course with Chris White and crew of Jocky Sanderson's Escape XC in Sederon and St.Vincent les Forts, France.

A bit of thermalling at our home sites Mt.Woodside, Agassiz and Mt.Mackenzie, Pemberton.

The Flying Circus (XC Course Day 6)

Friday.

Last day of the course and the Mistral is waning.

An ambitious plan - St.Vincent to St.Andre, conditions allowing.

I have not been an inch south of Dormillouse, so the flight plan briefing is a sort of Greek to me. The collection of town, valley, and peak names is lost in a Francophone alphabet soup. It becomes clear my plan is going to be simple, find a guide heading that way, get high and keep them in sight. Even if I lose the lead guide, odds are another will be venturing along behind with a slower mini gaggle - simply wait by thermaling in place with a wide valley/LZ within easy glide.

That was the plan. Little did we know, the pilots of the Haute Alps had a very different experience in store for us.

The lingering remnants of the Mistral means this is still the only flyable site in the region and with the improving conditions it appears that every pilot with the day off has made the St. Vincent pilgrimage. A similar trek appears to have been undertaken by the neophyte public, looking to savour their first taste of free flight.

In other words, it gonna get crazy up in here.

Arriving at launch, the conditions are still fairly docile. But with the sun and tourists out in full swing, this doesn't present a problem for the tandem operators. The TMs simply adapt to the conditions by adapting the customer they take. Miniature passengers toting similarly scaled  harnesses accompany the TMs to the launch area. Chris points out that the size of the passengers steadily increases in conjunction with the conditions. I gather the French have a different set of rules with respect to minors and waivers than we do in British Columbia (a waiver signed by a guardian on behalf of a minor back home is not enforceable in court).

Over the course of an hour the passengers start to approach adult size and a mass of pilots start to get ready. Looking at the crowd in the set up area, we could ultimately see upwards of 30 wings trying to concurrently work the 1 km long ridge. Under normal circumstances this wouldn't be an issue as better pilots would climb out and move to one of the local peaks to jumpstart a cross country. But with the clearing weather, the inversion at launch is more established. And no one cares.

A pair of queues form at launch, the north for tandems and the south for solo pilots. From the pair spawns a stream of launches continuing unabated for at least an hour. The best of the group can climb no more then 50 meters above launch, the worst linger in the ridge lift 10 meters below.

I launch into this forming Grand Melee to hear on the radio one of the guides recommending that the remainder of our group hold off for the time being. The ridge has turned into an airborne bucket of crabs, everyone scrambling to get out and hindering the efforts of all around them. Some are ridge soaring, some trying to thermal, some turning left, some turning right. Any success in finding lift by a lone pilot is frustrated as the mob converges in on them from every direction. A few mid air close calls ensue. I don't hear any yelling or cursing, yet.

It dawns on me that the safest place to be is below this herd (as no one has been able to climb out yet). No pilot in their right mind will follow someone who appears to be on the verge of sinking out. I push out, drop down to just below launch height, drift back in, and surf the dynamic lift from the valley wind. A moment of much needed tranquility. I now have to figure out how to get away from this mess.

The largest problem is that the climbs are still weak. As climbs are found, the herd stampedes in and prevents any further progress upwards by the (un)fortunate discoverer. I need to get a climb that is far enough away from the herd so that by the time they see there is lift, I will be at or above the highest pilots.

This means getting out of phase with the gaggle.

When the herd stampedes north, I must push south.

When the herd jumps on a climb, I need to push on.

Get enough horizontal separation so that when I find a climb, the vertical separation will follow quickly. This means I need to wait for the remainder of pilots to be opposite me at either the far north or south end of the ridge before I start circling.

Then it happens, a poor soul finds a climb just south of launch near the bowl and starts to circle. The sharks swarm him and more or less rip his chances of climbing out to shreds. I turn around and head north to the very opposite end.

Figure eight-ing back and forth, I drift up to launch height. Patience. Watch the shark swarm. They pay me no heed.

A thermal.

A lone wing has turned and is moving my way.

A quad of wing overs lets the interloper know in no uncertain terms that his company is not appreciated. He turns back. In a thermal, nothing says 'get off my lawn' like wing overs.

I start to circle and climb out. This catches the sharks attention and they speed bar towards me. But it is too late, they can only maintain at the upper extent of the dynamic lift and the thermal has lifted me above it.

I drive south, above and in opposition. Hooking the thermal that the uncoordinated mass wasted, I move onto the slopes of Dormillouse.

The Flying Circus now left far below and behind.

The end result was a jaunt past the peak and south in the direction of St.Andre. I didn't make it very far as only one of the guides, Chris, was able to get away. He landed just south of my eventual LZ.

Sometimes the gaggle is greater than the sum of its parts, other times it cannot even rise to the level of its weakest link. Today was a lesson in the latter.

A Hat Trick (XC Course Day 5 - Part 3)

Racing the setting sun and a blend of pleas to call it a day to retire to either home or the EckoBar down on the lakeshore, I set up for Round Three.

This will have to be a short one, lest I lose my ability to select my seat for the bus ride home. With the pilots on our course having differing opinions on how often flying clothing should be cleaned,  one should keep in the back of their mind the ability to grab a seat with an open-able window for the hour plus ride home. The key is near window, upwind.

The ridge is still working and folk are maintaining easily in the residual valley westerly. After twenty minutes of beats back and forth, I decide to finally give the top landing LZ a go. Both because the conditions have tamed enough to reduce the combined effect of rotor and compression zone lift AND because if I land in the bailout, any chance to avoid a two front variant of the Battle of Ypres is kaput.

Top landing is a rather new beast for me with early landing attempts by local pilots at our primary sites being accurately described as top crashing. My attempt would be caveated with:

1. Do not go over top of the parking lot as the rotor could still be nasty.
2. Be mindful of the compression zone lift.
3. Keep out of the way of the tandems still flying and landing.
4. Make sure the attempt, if aborted, still leaves enough height to make a bailout of some form.

A few extra beats to ensure no tandems would be landing soon, I start a down wind run.

The plan: hook in low directly from the downwind leg with a diving turn that should have me on the ground before the parking lot, have me in the compression zone as short a time as possible, and leave me a lot of runway if I do need to kill altitude.

The execution:
 
Downwind leg.
 
The hook through base and final.
 
 Plane out just before touching down.

 And voila.

Uh oh...
 
 
Chris came over right afterwards to inform me that while the landing was beautifully executed, it was poorly planned. As the site is still prone to westerly gusts, if one were to occur while I was on final, I could have been blown into the parking lot to my right. A wiser approach is to do the same downwind leg, but turn away from the hill then back upwind and drift in at an angle. This gives the best chance of mitigating the effect of a gust. The point was well taken and will certainly be a significant consideration in future top landing attempts.
 
The day done, the wing packed up, and a windowed, upwind seat of choice acquired in the bus.
 
So ends the Hat Trick Day - a scratching low save when all others bombed out, fun with clouds and low collapses, and a first top landing. This is the sort of day that builds a better pilot.

A Hat Trick (XC Course Day 5 - Part 2)

The day has just started and a low save already under the belt.

The wing is a spaghetti of fabric, lines, and webbing in the 2nd row of the van as we race our way back up for a second go. The majority of our crew has returned from a morn of via ferrata and itching for a different sort of climb. And unlike the day previous, the overdevelopment daemon has not yet reared its head overtop of the peaks. This will allow for a wider swath of experience levels to get out and clock a few more hours of airtime.

Myself included.

Emboldened by my earlier success, I quickly stake out a claim in the prep area and begin sorting my al dente Delta 2. The rush to get back up the hill has made for a rather jumbled mess, costing valuable time in getting kitted up.

Ballasted tandem.

A little plucky today.

In the meantime a tandem is set up, using a single helper as ballast. The tandem master pulls the wing up and the passenger is plucked a foot in the air. The TM maintains control of the wing and sets the passenger back on the ground. One thing that has consistently impressed me here at St.Vincent is the kiting ability of the TMs. On launch the wind is a gusting mix of west and north - typically west at flag and wing height, north some point in between. It is not uncommon to have a wall built, pull up, have the wing turn 90 degrees, then snap 90 degrees back on heading. Failure to control the wing through this process often times results in being dragged south over the back of launch to the top landing area.

Conditions have picked up considerably from this mornings scratch fest. A jaunt up the mountain and over the ridge to the main landing zone is easily within reach.

Some assistance from Stuart and I am ready to go for round two.

Another uneventful launch is followed by a series of beats from launch to the northern end of the 1 km long ridge, maintaining above launch height in the aggregate valley wind and thermals.

This trip has provided an amazing opportunity to work on ridge soaring in blended dynamic/thermic conditions, especially with respect to getting in close to terrain. Being able to differentiate between the two while still keeping mind to the gaggle of tandems is not a trivial task but critical if one wishes to leave the ridge and try for Dormilluse.

Sufficiently high above launch (for my liking anyways), I move to the bowl demarking the base of the mountain. Moving back to the bowl is not without risk, as the slope is shallow and the bailout is a very long glide into wind. Failure to quickly find a climb out means a tree skimming race back to the ridge with hope of at least enough of a climb to eek out a top landing. Despite these concerns, I place faith in my ability to scratch and dive in at launch height.

It takes little time to spot movement in the trees leading up the gentle slope towards the bowl. I approach and feel the wing being pulled in by the air. A flat figure eight is all that is needed for this conveyer belt of air to take me up along the slope with it.

The air reaches a high point and releases.

In the meantime, an Ozone tandem (Chris) and Advance Sigma (Andy) catch my attention above and to the west. I hook into their thermal from below and climb up to them. While flying with partners is advantageous in finding lift, it can work against the pilot when lift is found. Working a thermal alone only requires attention on the feel of the lift, adjusting course based solely on the thermal.

On the other hand, flying in a pair+ requires attention with respect to sharing the thermal and not hogging a core especially if relatively narrow. This can mean lift is not capitalized upon as efficiently as possible, leading to a situation where a lower lone glider thermals up in the core to a pair of wings. Such as in my case now.

Before reaching Chris and Andy I slip out into weaker lift and try blending into their left hand turn.


Chris, the guide, on tandem.

Andy on the Sigma.

Trying to blend in.
My attempts to tighten up again on the core while level with them appears to cause some frustration as they head southwest shortly there after.

They leave under a welcoming blue sky.

Meanwhile, what was a peak backgrounded by blue sky is now clouded in and getting dark rather quickly. The shadow of this quickly materializing beast pushes upwind into the middle of the valley. A glance across the lake to the sister peak, Morgonne, reveals a similar situation unfolding.

Two minutes later...

Base dropping.

Time to skeddale.

A straight line shot away from the peak and I begin setting up an approach to land. The wind, as expected, is coming up the valley from the lake at between 20 and 30 kph. The upwind side gets rather thermic this time of day and one could spend quite a bit of time getting bounced around without losing any height if they were to dwell there. So I set up just downwind of the lz and creep in.

A right hand turn onto final just above tree top height. A pair of mild chirps from the vario.

Nice straight in approach.
WHACK!

Nothing says Wake up! like a riser in the face.

The left side of the harness drops with an immediate 90 degrees left turn and the start of a dive.

A sharp jab of the left brake, a touch of right, and as best a right weight shift as I can do hanging out of the harness. The dive stops, I ease the wing back onto final, and land.

Lets try this again.
Wheh.

Word on the ground was that it looked like a 50% left asymmetric collapse. Up high, a non issue. On final, a perfect way to get ones pulse racing.

In anycase, daylight remains. Pack it up and jump in the bus for round three.
