jumper03 0 #1 July 21, 2003 With all the talk over the forums about tracking, horizontal seperation etc., just how far might a jumper be able to track (assuming they are an awesome tracker) if going into a track right out the door down to pull time? Now I know the birdmen are all going to chime in, so for simplicities sake, the jumper is wearing a standard suit with no booties. We talking 1/4 mile? 1/2 mile? Over a mile? What kind of glide paths can you get? What's the trade off of horizontal speed to vertical speed? (I know what I want to do next weekend! ) Thanks, JumpScars remind us that the past is real Quote Share this post Link to post Share on other sites

indyz 1 #3 July 21, 2003 Certainly over a mile from 13 grand. Tracking along a highway in a tight suit with booties, I've kept up with traffic. I don't consider myself an awesome tracker. Two miles would be over a 1:1 ratio, which I think would be tough, but at least one person on these forums claims to have done it, and I have no reason to doubt his integrity.

Just to add $0.02, ProTrak graphed speeds are notoriously unreliable due to pressure changes as you change body orientation. Someone coming out of a dive into a track will doubtless have a large pressure transient that gives a bogus speed. The averages are more reliable, but I think freefall times are the best indicators.... The only sure way to survive a canopy collision is not to have one.

billvon 3,107 #5 July 21, 2003 Jumpers have achieved 1:1 tracks with RW suits; that's about two miles from average exit altitudes. Generally a good track will sacrifice vertical speed for horizontal speed. Quote Share this post Link to post Share on other sites
BlueEyedMonster 0 #6 July 21, 2003 I've gone more than 2 miles perp to jump run in 9000 ft of freefall. Quote Share this post Link to post Share on other sites
freakydiver 0 #7 July 21, 2003 I covered something like 2 miles - from one side of the Lost Prarie to the other side - maybe even 3 when I won the intermediate tracking contest five years ago. Anyone thats been to LP know the width of that valley??? -- (N.DG) "If all else fails – at least try and look under control." -- Quote Share this post Link to post Share on other sites
