The Stall Warning Transmitter (SWT) is an Angle of Attack (AoA) Probe fitted with a built in Stall Warning Computer. The SWT provides Local and Normalized AoA signals for indicators, multifunctional displays, and flight control systems. It also provides outputs for audio warnings, stick shakers, and stick pushers at the appropriate time of the flight envelope. It accepts signals from flaps, spoilers, speed brakes, and other control surfaces and uses them to modify the stall warning characteristic curves.
