What is the function of the standby attitude indicator?

• A. Indicates heading relative to magnetic north.
• B. Measures rate of climb.
• C. Provides a continuous indication of aircraft attitude in pitch and roll.
• D. Displays true airspeed.

Answer: (C)

The standby attitude indicator is a backup instrument that continuously shows the aircraft’s orientation in pitch and roll. It provides a stable horizon display even if the primary attitude indicator fails, helping you maintain proper aircraft attitude by indicating how nose-up/nose-down you are and how the wings are banks, relative to level flight. It isn’t used for heading, which is provided by the heading indicator, nor for rate of climb (vertical speed) or airspeed.
