mac2501 0 #1 Posted May 27, 2019 Lads/Ladies/Non specific Genders. I'm a bit of an IT and kit mong I have an Ares 2, Viso 2 , Optima 2 and an Alti-2 Atlas. Whats the easiest way to figure out speed in Free Fall ? many thanks Quote Share this post Link to post Share on other sites

RiggerLee 61 #4 May 28, 2019 Not sure exactly what you are looking for. Depending on what you are looking for you might want to correct it for density altitude to get a corrected air speed. If you just drop it in to exel for instance you'll wind up with true air speed which is relevant in some circumstances but in for some things corrected might give you a better reference across the jump.

timotee 0 #5 May 29, 2019 (edited) Using the Viso II: Can't you use the "Jump Profile Playback" function to find the slowest speed? But could be kind of annoying to "search" for the lowest value ;-) Edited May 29, 2019 by timotee Quote Share this post Link to post Share on other sites
aonsquared 9 #6 May 29, 2019 Actually, a Flysight would probably be even better, as it uses GPS and is not dependent on barometric pressure. Quote Share this post Link to post Share on other sites
za_skydiver 0 #7 May 30, 2019 Flysight is now the only recognised device for speed skydiving. If you wanna know how fast your going, GPS is the only way. Quote Share this post Link to post Share on other sites

I've been questioning that. If you keep the exact same body position through freefall, you'll slow down as you fall and air density increases. I wanted to use visual or audible aid for base speed control in big ways, and in this case, normalizing based on barometric pressure would be ideal.
