| It's supposed to
be 4° in Chicagoland today. 4°. Go get 'em winter!
It's good to be in Phoenix.
Today was windy even for hiking in the mountains although we did
anyway. It was, after all, 75°F. Sitting on top of Silly Mountain (yes,
that's its name) we swayed to the gale and pondered how ugly it would be
under a paraglider at that particular moment.
It was perfect, however, to get some pictures that illustrate high wind
techniques. This time it would be to show how the stabilo line can be used
for clearing tip tangles on the ground. You've no doubt had the wing plop
down in a heap while kiting. The fabric strangles itself in lines when you
go to inflate it even though it was kiting nicely just moments
before. The cure is frequently a simple pull of the stabilo line (usually
the outer B line). That will pull the fabric by its tip, through other
lines, and clean it up nicely.
After pictures it was time for fun. A paraglider is just like a big
traction kite so I treated it like one. I'd get the glider leaning one way
and let it pull me for a while then tilt it up and over the other way to
go sliding in the new direction. Of course I'm also going downwind but it
allows probably 45° each way. Great fun and I never got my bottom side
dirty.
Alas, it never calmed enough to fly. In fact, it's nighttime and the
enterprise is still rockin' and whistling to the howl. That allowed time
for some necessary maintenance on the Enterprise and paramotors. There's
much more that needs to be done so hopefully we'll get some bad weather to
give us sufficient opportunity. Sometimes I don't know how these Phoenix
people get anything done. Sunny and nice every day. Sunny and nice. Tough
to take.
Friday
Morning arrived with a whimper. None of the forecast wind showed up. Mo
Sheldon, located at a site south of town about 20 miles, reported a strong
east breeze of 20+ mph while we experienced a steady 2mph west. It
gradually increased and turned north then northeast until becoming around
10 mph by noon. Nothing like the 22 mph gusts in the aviation terminal
forecast. The morning's calm enabled more pictures including a series
showing the cross-armed reverse, a method of reverse inflating in very
light winds. The sun angle required me turning to the right which is
opposite my normal direction. It's surprising how weird that feels. Doing
inflations repetitively like this certainly makes me better at it but boy
it's a lot of work! Thanks to Tim for being an expert photographer. We
would take a series of shots then go look at them on the computer. Some
just didn't work. They didn't tell the story. In fact most are like that
and we wind up doing different angles and zoom levels to find the one that
worked best. I keep in mind Dennis Pagen's biggest contribution to the
book was "this photo series doesn't work" or "I can't
figure it out from this descriptions". By combining our ideas on
execution the final product will be much better. These pictures and
technique descriptions will likely be used in upcoming UltraFlight issues
before becoming part of the eventual 2nd edition PPG Bible. We're now on
the road towards one of Mo's sites and will likely get some more high-wind
play this afternoon. |

behind us. Thankfully the wind didn't blow the camera away.

It was gusting to over 16 mph.

Going left then right. Back and forth--what a blast. The harness is
minimalist, it comes from a mountain climbing shop for around $55.  
Tim
shows why the V layout is used by pulling tension on the lines. It's a
trade-off because a wing laid out this way will tend to have the center
cells inflate first but will not inflate quite as fast as one laid out
straighter across. The next picture is yours truly during one of a series
demonstrating the cross-armed reverse. It's obviously a lot of work. Each
inflation we did like this worked as advertised but this one was the
clearest because he zoomed in closer to see what was happening with the
risers. |
