Angle of Attack (AOA) Display
4.9 Angle of Attack (AoA)
The Aspen Evolution Angle of Attack indicator, if enabled, calculates and displays AOA
from flight envelope data collected from the AHRS, Air Data Computer and a certified
GPS. When calibrated properly it calculates the aircraft AOA and displays the Flaps UP
and Flaps DOWN AOA on the color coded AOA bar display.
The Evolution Angle of Attack provides the pilot a visual display of the AOA trend
and the trend towards stall simultaneously in both the Flaps UP and Flaps DOWN
configuration.
