Stall Warning System
The Learjet 35/36 incorporates a dual, independent, stall warn-
ing system that provides an indication of an impending stall; it
also commands an aircraft nose-down attitude as corrective
action.
During flight, should the AOA indicator needle cross over the
green/yellow border, the computer actuates the stick shaker
and the red STALL light flashes. If AOA continues to increase,
and the aircraft nears aerodynamic stall (indicator needle
reaches yellow/ red border), the computer actuates the stick
pusher to reduce the angle-of-attack and the red stall light illu-
minates steady.
On FC-530 aircraft, a nudger is activated with the shaker. If
the nudger is inoperative, a warning tone sounds to warn the
pilot not to decelerate further.
Both stall warning systems must be on and operational for
flight. The stall warning system can be tested using the rotary
test switch on the test switch panel. The test circuit operates
only with the squat switches in ground mode and the stall warn-
ing switches on.
