Definition
A gyroscopic flight instrument that displays the airplane's pitch and bank relative to the natural horizon. It uses a spinning gyro to hold a stable reference, against which a miniature airplane symbol moves to show the aircraft's orientation in real time.
Plain English
An instrument on the panel that shows whether the nose is pointing up or down and whether the wings are level or banked, by comparing them to a steady artificial horizon.
Context Anchor
Seen in analog instrument flying when using the attitude indicator as the main reference for airplane control.
Derivation
Attitude' here is borrowed from aeronautics, where it means the aircraft's orientation in space (pitch, bank, yaw) relative to the horizon. 'Gyro' is short for gyroscope, from the Greek 'gyros' meaning 'circle' or 'turn' — a spinning wheel that resists changes in its orientation, which is what makes the stable reference possible.
Why Pilots Care
Enables safe control of the aircraft when visual references are lost, directly preventing spatial disorientation and loss of control.
Intuition Check
Attitude does not mean mood or behavior here. It means the airplane’s nose-and-wing position compared with the horizon. Gyro does not mean the whole airplane is turning; it refers to the spinning part that gives the instrument a steady reference.
Example Sentence 1
After entering the clouds, the pilot scanned the attitude gyro to confirm the wings were level.
Example Sentence 2
During the steep turn, the attitude gyro showed a 45-degree bank that the pilot held steady until rollout.
