What is the Angle of Attack (AOA) Indexer?

Explanation:
The AOA indexer is a cockpit cue that visually shows the current angle of attack during approach and landing by lighting symbols. It’s designed to be active when you’re configured for landing—gear down and weight off the wheels—so you get a clear, at-a-glance indication of whether you’re in the proper approach AOA range. This makes it easier to manage descent and timing for the flare, since the indicator directly reflects lift-related attitude rather than other flight parameters. It does not measure bank angle or vertical speed, which are shown by different instruments.
