How many seconds does it take FLARM to compute a collision warning, once
the aircraft are within FLARM's radio range?

A warning is only issued if a dangerous approximation is detected. As
far as I understand, this information is updated every second. IOW the
algorithm doesn't have state that persists over position/velocity
updates. IOW, the warning is pretty immediate.

Objection. FLARM is a "collision-warning unit for sailplanes and light
aircraft." It's "movement prediction model" is "optimised for the
respective user." (from the manual). The FAQ states (in German) that
it's designed for ground speeds up to 249 kts and vertical speeds of up
to 256 m/s (the designers had skydivers in mind here . Range is given
between 1km and 5km, it strongly depends on how the antenna is mounted.

The last time I fell from an aircraft I dropped at
a leisurely rate of 60 m/s
