Low Airspeed Indicator

Drawing: Low Airspeed Indicator

The low airspeed indicator, located in the pilot instrument panel, measures and displays low airspeed up to 50 knots by horizontal (fore-aft) and vertical (lateral) direction indicators. Airspeed is sensed by the airspeed and direction sensor (AADS). The intersection of the two direction indicators is related to the circular scale to obtain resultant airspeed. A three position flag is used to indicate system failure, system operational or an over-range condition. The primary purpose is to provide wind speed to the FCC.
