Why is it called Angle of Attack (AOA)?
Alpha Systems AOA derives information from a custom designed AOA probe that is calibrated to the aircraft, in-flight, at a specific Angle of Attack known as “Optimum Alpha Angle”. The system, once calibrated, allows the display to give AOA readouts for the pilot to use as additional information during slow flight landings and takeoffs. Airspeed is the result of your angle of attack. Angle of attack is defined as the angle of the wing (cord) to the relative wind (direction of flight). Every aircraft has a different coefficient of lift based on the design of the aircraft and the design of the wing. The cord of the wing is defined as a line from the center of the leading edge through the center of the trailing edge. The Alpha Systems AOA probe mounting plate is designed to “cut to fit” a majority of existing inspection openings. Once cut to fit and mounting holes drilled to match the existing opening, our mounting plate becomes the inspection cover.
