How it Works - (cont.)
Typical AOA Probe Location
Alpha Systems AOA system was designed to take advantage, in most aircraft, of an inspection cover location that could be identified in clean air flow (undisturbed air) at ALL angles, from Cruise to Stall, and ALL flight attitudes, Slips or Skids and no part of the aircraft blocking with NO disrupted air into the AOA probe. Typical installation requirements are 1.) 2 foot outside the propeller ark, 2.) 6” back from the leading edge, 3.) 6” up from the trailing edge and not blocked as described above at
ALL attitudes.
AOA Probe and Mounting Plate
Our AOA probe is permanently attached with NO moving parts. This probe sends its’ AOA information corresponding to the AOA of the aircraft. The Blue and white arrows indicate the AOA sense ports that constantly samples any change of differential pressures when in flight, slow flight, take offs and landings.
Display Installations
Alpha Systems has many different LED displays available to fit any cockpit or pilot viewing requirement. Panel mounts, dash surface mount, swivel post mount and vertical mounting brackets help make the Digital LED displays easy to mount in any cockpit. Other features of ALL Alpha Systems AOA digital LED units are features such as; easy “one button” software calibrations, 16 brightness settings with a built in photo cell to switch from “night time” to “daytime” brightness presets, and an audio ON/OFF selection with a built in audio beeper, I/O interface for a remote beeper or the audio interface unit that allows audio in the cockpit headset options that identifies conditions of a significant increase of AOA.
