A. This subject contains two tasks. The first task is an operational test of the stall warning system. You will do the operational test in the control cabin.
B. The second task is a system test. The system test has these parts:
-Stall Warning Operational Test (Confidence Test)
-
SMC Discrete Inputs Test
-
SMC ARINC Inputs Test
-
SMC 1 AOA Sensor Input Test
-
SMC 2 AOA Sensor Input Test
-
SMC Flap Position Inputs Test
-
SMC Engine Tachometer Inputs Test
-
SMC to EFIS Interface Test
-
SMC Asymmetry Mode Test
C.
You will use the buttons on the front of the stall management computers (SMC) to do a BITE test and to monitor the inputs to the SMC's.
D.
In the system test, you will open and close circuit breakers in the control cabin, push buttons on the E-11 landing gear logic shelf, manually change the position of the AOA sensors, and extend and retract the flaps.
E.
In the Engine Tachometer Inputs Test you will connect a stall warning system test box at the engine tachometer transmitters inside the engine cowls. As an alternative method to do this test, you can connect a dc power supply at the engine tachometer indicators in the flight compartment.
