Under which condition is AOA information provided on the AOA indexer?

• A. Landing gear down and locked
• B. Flaps landing setting
• C. Angle of attack below 8.8 units
• D. Airpeed 5 to 10 knots above stall speed

Answer: (A)

AOA information on the indexer is shown only when the airplane is in landing configuration, specifically when the landing gear is down and locked. This setup ensures the angle-of-attack cues are most relevant during approach and flare, helping the pilot monitor stall risk right when configuration changes matter most. With the gear up, the indexer display isn’t activated so the cockpit isn’t cluttered with AOA data during cruise or other phases where it’s less critical. The other options don’t control when the indexer displays AOA: flap setting, a fixed AOA value, or being a certain distance above stall speed aren’t gating conditions for showing the AOA information.
