At this year’s AirVenture, Belite Aircraft introduced its improved Angle of Attack sensor and display gauge.
Calibrated from 0 to 12 (normal cruise to imminent stall), it features a frictionless mass balanced windvane sensor, combined with an LED display that is readable in direct sunlight, according to company officials.
It is supplied as a complete system, including the weathervane sensor and housing, along with the cockpit display. It is calibrated in flight by pushing a button: A short touch marks the imminent stall speed, and a long touch marks normal cruise speed setting.
That is all that is required for calibration, and the system then provides continuous feedback as to the current angle of attack, according to company officials.
Featuring a price tag of $499, the AOA system is compatible with most experimental, ultralight, and Light-Sport Aircraft (with manufacturer approval).
The gauge is designed for the pilot’s choice of Heads Up reflective display mounting (HUD) below the windshield, or conventional panel mounting. The Heads Up mounting option allows the pilot to concentrate on landings without losing sight of AOA information, company officials note.
It may be mounted on the leading edge of many aircraft, or also off the lift struts. It may also be mounted fuselage flush, especially on the forward portion of pusher aircraft.
