What is obtained from the attitude indicator?

The attitude indicator provides essential information about an aircraft's orientation relative to the horizon, specifically indicating the degree of bank in flight. It displays whether the wings are level, climbing, or descending, which allows pilots to maintain proper aircraft control, especially during maneuvers. Understanding the degree of bank is crucial for performing turns safely and effectively.

While altitude, airspeed, and heading are vital flight parameters, they are provided by other instruments on the aircraft. The altimeter displays altitude, the airspeed indicator shows the speed of the aircraft through the air, and the compass or heading indicator provides directional information. Thus, the primary function of the attitude indicator is centered on showing the aircraft's bank angle, making it an indispensable tool for pilots during flight operations.
