The red arc on the AOA gauge begins at which AOA value?

• A. 0.6 AOA
• B. 0.8 AOA
• C. 0.9 AOA
• D. 1.0 AOA

Answer: (B)

Understanding how the AOA gauge communicates risk at a glance is key. The display uses color bands to show safe and caution zones: the green (normal) range covers typical flight, and as you raise the angle of attack toward stall, you move into the high-AOA region shown by the red arc. For this aircraft, that red warning begins at an AOA of 0.8. That point marks the boundary where the margin to stall tightens quickly, signaling you to reduce AOA to maintain safe control. Values below 0.8 are still in the safe range, while values at or beyond 0.8 sit in the caution/stall region. So the red arc starts at 0.8 AOA.
