STALL WARNING TRANSMITTER
Description:
The Stall Warning Transmitter (SWT) is an Angle of Attack (AoA) Probe fitted with an internal Stall Warning Computer that provides local and normalized AoA signals for indicators, multifunctional displays, and flight control systems.
BASIC FUNCTIONS:
The Stall Warning transmitter provides local and normalized AoA signals for indicators, multifunctional displays, and flight control systems and is also capable of providing a full range of drive signals for audio warnings, stick shakers, and stick pushers while accepting information on flaps, spoilers, speed brakes and other control surface positions and using it to modify the real time stall warning characteristic curve to provide the highest accuracy and safety.
