vonSanta 0 #1 August 25, 2003 Am still a newbie with 36 jumps, gone through AFF. Directly after that I experimented a lot with sitflying but after I managed to hold it for a bit an instructor told me to stop, because the student rigs aren't free fly qualified. It seems an instructors job is to scold you as much as possible Anyway, lately I've been working on my track - back one direction, then 180, then back, 90 degree to line of flight as told. Yesterday I was flying parallel and directly above a road, so thought I'd see if I could move with the cars. Initially it wasn't possible, so I used lower abs to get legs further down, shoulder inwards to fold a "cup", arms quite near body. I shot forward quite a bit faster now, and was amazed to see the cars going about the same speed as me. When I stopped the track there was quite a bit of relative wind from the track, BUT... In the process of trying to go fast, I appeared to have developed a slight nose-down position. Am worried that I'm losing too much altitude on the track - supposedly it's the other way around compared to box, right? Experimented a bit with arms position but it appears to be the shoulders that cause it - the more I bend them inwards, the more my position points slightly downwards. Haven't talked to an instructor about it as it was very busy at the DZ yesterday. Would like some advice here so I don't develop a bad habit. Any more bad habits and my personality with be overcrowded with 'em Santa Von GrossenArsch I only come in one flavour ohwaitthatcanbemisunderst Quote Share this post Link to post Share on other sites

Any more bad habits and my personality with be overcrowded with 'em Read the thread that Amazon linked - but to answer your specific question, you have to be nose down in order to deflect air backwards and develop forward drive. The best trackers are achieving 1:1 glide ratios, which means the flight path is 45degrees down. To get good lift your angle of attack with respect to the airflow needs to be some 10 - 20 degrees, which means that relative to the ground you will still be 20 - 30 degrees nose down. (All numbers approximate, I don't think anyone has measured the Cl/Cd vs angle of attack of a human yet.)... The only sure way to survive a canopy collision is not to have one.
