4B.4.11 STICK LIMIT
STICK LIMIT
Control stick limiting system (variable elevator stop) has
failed.
The variable elevator backstop is activated depending on the position of the POWER levers
and the position of the flap selector switch. The system has two failure modes which can
be identified as follows:
(a) Both POWER levers are in a position for a power setting of more than approximately
20 % LOAD, and the FLAP selector switch is in LDG position:
CAUTION
The variable elevator backstop is inoperative. In case of
stalling with "power-on" the handling qualities and stall-
characteristics are degraded significantly.
Do not stall the airplane in any configuration.
(b) At least one POWER lever is in a position for a power setting of less than
approximately 20 % LOAD, or the FLAP selector switch is not in LDG position:
CAUTION
The variable elevator backstop is active all the time, reducing
the maximum elevator "pull"-deflection. This results in
reduced elevator capacity. In this case it is important not to
reduce airspeed below required minimum v
