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, patented technology addressing FAA's key issue for general aviation safety.
Angle Of Attack (AOA) Indicator
Technology That Matters
The Aspen Avionics Angle of Attack (AOA) Indicator enhances your Evolution flight displays with real-time angle of attack information, improving stall margin awareness and situational understanding.
This patented, software-only upgrade integrates directly into
Aspen PFD and MFD displays without adding external
sensors or hardware, making it a simple way to increase
safety in general aviation aircraft.

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.
