ON CARABINERS
(Tom Webster)
I'm not an expert on carabiners, but I have always felt uncomfortable
using aluminum carabiners for paragliding. Coming from a hang gliding
background I was always told that aluminum ones can develop hairline
cracks from being dropped, and eventually fail. There have been a
handful of failures over the years during preflight hang checks, luckily
none in the air. I have never heard of a steel biner breaking. HG pilots
always use steel biners or two aluminum ones.
One could argue that since we hang from two biners in a paraglider,
we're safe because the stress is half on each one. However, we use the
same ones for tandem flying and we always put more than a body weight on
one when we're weight shifting. Isn't that just as dangerous as hang
gliding with a single aluminum biner, which HG pilots swore off long
ago? Or is it stupid to bring this up, since thousands of tandem pilots
around the world can't be wrong?
We still need someone in the biner biz to step forward and sort us all out! -Chris
(Gordon Grice)
I have witnessed a situation where the push-button of the biner
was being pressed by some jammed webbing. In a no load situation (standing
on launch), this easily resulted in the gate opening allowing the spreader
loop to fall out. If you are operating with these push-button type biners
you should take a very good look at how the buttons are situated relative to
the harness webbing.
The Questions: Do you think the new "Push down - Quarter turn" biners from
Sup'Air are less likely to inadvertantly get opened? Has anyone launched
with the pilot not attached on one side and lived to tell about it? If you
could get an anonymous story, I would like to hear it.
ON LAUNCH MISHAPS
(Dale Covington)
I thought I might mention a recent incident where a fellow tandem pilot
had a brake line snag on his hooknife (In the Case) while launching at a
steep, windy launch. Could have just as easily been any of us, and made me
stop to think again about what I have on my harness that could potentially
snag lines. I would like to find a tandem harness, if you, or anyone on the
list knows of a used one that's reasonably priced, I'd like to hear about it.
ON RESERVES
(Dale Covington)
It seems that the industry wide problem of reserve comparisons seems to
gain more importance in this context. Reserve "A" may be similar size to
Reserve "B" but descent rates may be quite different, along with stability,
opening characteristics, etc. Anyone with Ideas on comparing apples to
oranges?
TANDEM MINDSET
(Ken Hudonjorgensen)
This is probably review for most of you, but interesting anyway...
WHAT ARE THE DIFFERENCES BETWEEN TANDEM AND SOLO MINDSET?
(compiled by a group of T2-T3 candidates taking a course with Ken)
1. Greater turn radius
2. Larger space needed for LZ
3. Passenger may need
4. More adrenaline
5. Another life in your hands: take less risks
6. May take longer to get down
7. Drag potential
8. More danger when landing in new LZ
9. Need more room: slower turning
10. Give off big wake
11. No speed systems
12. May be more distracted
13. Every flight changes weight
14. Preflight is more important: consequences are greater (another body & liability & site)
15. Flight plan must include passenger
16. Ability to move (kiting) is restricted
17. View is obstructed (flair and traffic)
18. With tall person may not control the run
19. Brake feel and input is different
20. Flare for passenger
21. Sex can be dangerous (distracting) be professional
22. Maneuvers are drastically different
23. Don't try to out-fly solo or other gliders
24. Weight shift is variable (wt. on the glider & is passenger helping?)
25. Run will not be as effective in light wind
26. Lay out is different (careful)
27. Inflations (passenger may not slide well)
28. Be aware of and educate your ground crew
29. Be pickier about care and age of equipment
30. Careful inflation check before flying
31. Check with passenger about medical condition
32. Passenger may get sick
33. Hook in process is different
34. Comfort for passenger (lavatory needs)
35. Notice passengers emotional state
36. More information to process
37. Emergencies are compounded (PLF etc)
38. Have appropriate mindset for tandem
39. Check yourself for bad habits (complacent)
