Stall Speed and Minimum Air-Speeds
The stall speed and lowest flying speed of the motorglider depends on the
configuration of the aircraft and the mode of operation.
The stall speed is the speed at which a stalled flight state is reached. The
minimum air-speed is lowest stationary speed that is controllable (reaching of
the control-stops).
Warning:
When recovering from a stall in horizontal flight,
an altitude-
loss
of
100 ft / 30 m
is possible. In
turning flight
, an
altitude-loss
of
130 ft /
40 m
is possible. If the pilot
reactions are
delayed
, the
altitude-loss
may be more than
200 ft / 60 m
.
