Definition
A gyroscopic flight instrument that displays the aircraft's pitch and bank attitude relative to the natural horizon. It uses a gyro-stabilized horizon bar or sphere as a reference, allowing the pilot to determine the aircraft's orientation in space without outside visual references.
Plain English
An instrument that shows whether the nose is pointing up or down and whether the wings are level or banked, even when the pilot can't see the real horizon outside.
Context Anchor
Seen on the instrument panel during instrument flying, especially when using the aircraft instruments instead of the outside horizon.
Derivation
From Latin attitudo, meaning 'posture' or 'position.' In flying, attitude refers to the aircraft's position relative to the horizon, not its emotional state.
Why Pilots Care
Provides immediate visual reference for aircraft orientation when outside visibility is lost.
Intuition Check
AI does not mean artificial intelligence in this context. In this chapter, AI means attitude indicator, the instrument that shows the airplane’s position relative to the horizon.
Example Sentence 1
Entering the clouds, the pilot transitioned to instruments and used the AI to keep the wings level.
Example Sentence 2
After the AI failed, the pilot transitioned to partial panel using the turn coordinator and altimeter.
