Freefall Speed

Recommended Posts

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.

Actually, a Flysight would probably be even better, as it uses GPS and is not dependent on barometric pressure.

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.
