What is a Standby Attitude Indicator and why is it essential for flight safety?

• A. A separate attitude source used if primary displays fail; it provides attitude reference and supports continued safe flight.
• B. A backup altimeter that uses radar.
• C. A separate heading indicator.
• D. A standby air data computer.

Answer: (A)

A Standby Attitude Indicator is an independent source of the aircraft’s pitch and bank information. It stays available even if the main attitude displays fail, because it has its own sensing gyro and often its own power. This keeps the pilot oriented in space and able to maintain control, especially in instrument meteorological conditions or during electrical or display failures. By providing a reliable attitude reference, it supports continued safe flight and controlled maneuvering until normal systems are restored or alternate guidance is established. It isn’t used for altitude or heading, and it doesn’t replace those instruments; its sole purpose is to give a dependable attitude reference when the primary displays aren’t available.
