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 PFD or Evolution 1000 MFD, and a certified GPS it does not require additional hardware, nor does it require any external aircraft modifications or sensors.
With a software upgrade to the Aspen EFD Pro or MFD1000 plus a short calibration flight, Aspen is addressing one of the FAA's most wanted safety issues for the general aviation community.
- 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.
