Pilot errors (releasing risers too slowly), bad trimming or particular conditions (rain) can result
in the wing not adopting trim speed on its own. In this case gently push the accelerator – the ATIS 3
will continously return to normal flight.
If no accelerator bar is mounted pull A-risers symmetrically for about 5 cm.
Caution: A B-stall is a stall, where the canopy does not fly any more.
Perform this manoeuvre at sufficient altitude only.
6. Performance & use of brakes
At 0 % brake (hands up in calm air) the ATIS 3 provides best glide. The speed is 37 to 38
km/h. Minimum sink rate is achieved at 10 to 15 % brake.
Beyond 30% brake, performance figures and the behaviour of ATIS 3 will change; performance
and roll-stability deteriorate and brake pressure increases heavily.
Very heavy brake pressure warns the pilot of an approaching stall-point (100 % brake).
Normally, best performance and maximum security can be found in the first third of brake travel.
