Re: [dontlikemustard] AAD Statistics

In reply to:
the Cypres Expert, which decides at 1000ft to activate at 750ft

That is a complete mischaracterization, or in other words, simply not true. I also think the Vigil "recalculation" frequency is a bit of marketing hype, and it is wrong to conclude that a Cypres "calculates" slowly in comparison.

Belly flying will result in a bit of a low pressure area where the sensor is on your back. That will be true for a Vigil also. To compensate for that, the actual firing altitude is adjusted. which makes it fire a bit higher if you're not belly flying at that time, and can also happen during canopy inflation (standing position).

Without the ability to determine a jumper's orientation, it makes sense to make the adjustment. You either allow the firing to happen lower for one scenario (already very low - I wouldn't want it lower), or allow it to happen higher for the rest. I think the Germans took a reasonable approach.
