What components are included in the stall warning/stick pusher system?

The stall warning/stick pusher system is designed to prevent aircraft from reaching a critical angle of attack (AOA) that could lead to a stall. The correct answer identifies that this system includes two AOA sensors and two computers, along with the MAU (Multiplexed Avionics Unit).

Having two AOA sensors provides redundancy, which enhances safety by ensuring that if one sensor fails or provides erroneous data, the second sensor can take over and continue providing accurate AOA information. This redundancy is crucial in an aviation environment where reliable performance is necessary to avoid stall conditions.

The two computers process the input from the AOA sensors and make decisions on when to activate the stall warning and, if necessary, the stick pusher function, which helps to push the control yoke forward to decrease the angle of attack and recover from the impending stall.

The MAU plays a key role in the system by facilitating communication between the various components, consolidating data, and ensuring that the information is processed correctly for reliable stall warning and recovery actions. Hence, the combination of two AOA sensors, dual computers, and the MAU makes for a comprehensive and robust stall warning/stick pusher system that enhances the operational safety of the aircraft.
