Angle of Attack and airspeed are the two fundamental components of lift. The Alpha Systems AOA provides a visual display of the amount of available lift throughout its slow speed envelope regardless of the many variables which act upon an aircraft. The Alpha Systems AOA also provides a continuous visual reference of an aircraft's margin over stall at any airspeed. This allows a pilot to continuously monitor their aircraft's performance since the Alpha System AOA responds instantaneously to pilot control and wind conditions.

The probe is solidly mounted under the wing replacing an inspection cover on most airplanes. Twins, jets and ultra-lights with pusher props can mount the AOA probe on the nose or canard. The AOA probe must be mounted in clean air (undisturbed) and a minimum of 2 feet outside of the propeller arc. The AOA probe has two ports that receive ram air (dynamic pressure). The design of our AOA probe allows the instrument to monitor the change of the differential pressure to be calibrated to the aircraft’s angle-of attack and displayed in the cockpit. Once calibrated, the probe will give the pilot an instantaneous AOA reading based on the aircraft’s angle-of –attack.
