Performance & use of brakes
AROLLA 3’s best glide is at trim speed (no brakes) – about
36-37 km/h.
The minimum sink rate is achieved by applying approx.
15% brake.
When using more than 30% brake the aerodynamics and
the performance of the glider deteriorate and the brake
pressure increases rapidly.
The higher the brake pressure, the greater the risk of an
impending stall which will occur at full brake travel (100%
brake).
In normal flying conditions the optimum brake position, in
terms of performance and safety, is within the top third of
the braking range.
