Angle Of Attack (AOA) Indicator
...if the test pilot of an aircraft needed an angle of attack indicator to stay out of a stall, then shouldn't every aircraft have one?"
-NASA research document on AOA effectiveness
Simple software upgrade for Evolution displays provides a unique, patent-pending technology addressing FAA's key issue for general aviation safety.
Angle Of Attack (AOA) Indicator
Technology That Matters
Since Aspen's Evolution AOA indicator calculates angle of attack from the flight envelope data received from the air data computer and attitude heading reference system (AHRS) integrated in the Evolution 1000 MAX PFD or Evolution 1000 MAX MFD, and a certified GPS it does not require additional hardware, nor does it require any external aircraft modifications or sensors.
With an affordable software upgrade (under $1K) to the Aspen MAX PFD or MFD1000 MAX plus a short calibration flight, Aspen is addressing one of the FAA's most wanted safety issues for the aviation community.

Key Benefits
Improves safety - provides real-time flaps up and down stall margin awareness - enables the pilot to see the available lift before changing the configuration - crucial when making a go-around.
Intuitive display - provides an immediate, clear visual display of trend toward stall and stall margin. Pilot comprehends important information at a glance.
Easy Installation - requires no additional probes, wiring or equipment. Installation cost and down time are minimal.
Primary Field of View - AOA is displayed on the Aspen PFD or MFD. Information is displayed in pilot's natural field of view.
