What is the primary purpose of the attitude indicator?

The primary purpose of the attitude indicator is to show aircraft orientation relative to the horizon. This instrument is critical for pilots, particularly when flying under instrument flight rules (IFR) or in conditions where visual references are limited or absent. By displaying whether the wings of the aircraft are level and whether the nose is pointing above or below the horizon, the attitude indicator allows pilots to maintain proper control of the aircraft's flight path.

Maintaining orientation is essential during various phases of flight, especially during turns, climbs, and descents. This ensures that the aircraft stays in a stable flight configuration and aids in preventing unintentional maneuvers that could lead to loss of control or accidents. The attitude indicator serves as a crucial visual reference point for pilots to make informed decisions about aircraft maneuvers without relying solely on outside visual cues, which may not be available in inclement weather or nighttime flying.
