Zoter 0 #1 November 8, 2003 If I exit at 13K and pull at 4K.......assuming I fall on my belly at approx 120mph...how long is my freefall...and is there a nice simple calculation to work this out that incorparates exit altitude and pull altitude?

Jimbo 0 #3 November 8, 2003 At 4K you're about 24 seconds from certain death, at 3K it's about 18, and about 12 at 2K. Does that help? - Jim"Like" - The modern day comma Good bye, my friends. You are missed. Quote Share this post Link to post Share on other sites
Casch 0 #4 November 8, 2003 120mph = 176ft/s The first 1K ft takes approximately 10-12 seconds, then every 1K ft after that takes approximately 5.5 seconds. T = Freefall Time E = Exit Altitude (i.e. 3 or 10 or 13 etc.) P = Pull Altitude (i.e. 3 or 10 or 13 etc.) T = ((E - P) - 1) * 5.5 + 10 Quote Share this post Link to post Share on other sites
Zoter 0 #5 November 8, 2003 Thanks...thats the ticket ! and damn....Jimbo... I was thinking about the time I just had...rather than the time I had left !!!! but thanks for the clarity anyways Quote Share this post Link to post Share on other sites
Jimbo 0 #6 November 8, 2003 Think of it this way, what's behind you isn't likely to hurt, what's in front of you though could kill you. (I suppose that wouldn't hurt for too long though. ) - Jim"Like" - The modern day comma Good bye, my friends. You are missed. Quote Share this post Link to post Share on other sites

Zoter 0 #8 November 9, 2003 Yeah jimbo there its important to know that side of the equation as well......although....I wont need to be so accurate that I can enter it in my logbook afterwards Quote Share this post Link to post Share on other sites
