FlySight was designed from the ground up for wingsuit pilots and does one truly revolutionary thing...

FlySight provides real-time audible indication of glide ratio, horizontal or vertical speed.

If you've used other GPS receivers, you know the drill. When you land, you review data from the jump. If you're lucky, or if you've planned a very simple jump, you might remember what you were doing when your glide ratio maxed out. On the next jump, you try to do it again.

FlySight speeds the learning process.

When you change your body position, you instantly hear a change in the tone. Your brain easily connects this feedback with your precise body position, making it astonishingly easy to remember what worked and what didn't.

FlySight handles the dynamics of freefall exceptionally well. FlySight can be turned on a few minutes before exit, and begins providing audible feedback immediately after exit.

Here, we discuss a sample data set from a jump using the Prodigy 2 (not the same jump as the video above). The log file itself can be downloaded here:

For this flight, there was a moderate wind from the west. The flight line went west about 1.25 km, then north 0.75 km, then 2 km east.

For real-time feedback, this is enormously superior to a method based on differences in position, because the receiver's velocities are accurate to 0.1 m/s.

As expected, the glide ratio going west is slightly worse than on the return flight, because of the wind. One of the remarkable things about FlySight's real-time feedback is that the precise value of the glide ratio is not important. What is most clearly perceived is the change in glide ratio due to changes in body position.

This is a complete jump with the Prodigy 2 and FlySight.

The FlySight audio track comes from the jumper being filmed. The audio was reconstructed afterward, using information recorded during the jump, and then overlaid on the original video. The reconstructed audio track was produced by a FlySight, and recorded directly from its audio output, in order to make the reconstruction as authentic as possible. Synchronization was accomplished using the FlySight's LED, so the audio is as close as possible to real time.

The FlySight was in glide ratio mode with a maximum of 1.5:1. On this particular jump we had a significant headwind, but you can see that the tones produced by the FlySight still clearly identify changes in glide ratio resulting from slightly different body positions.

Andrew Levson is the man behind the camera. The jumper being filmed is Michael Cooper.
