How are gyro instruments primarily powered?

• A. By battery only
• B. Using a mechanical drive
• C. Electrically and by vacuum pump
• D. By wind energy

Answer: (C)

Gyro instruments are primarily powered through a combination of electrical power and a vacuum pump. This dual power source allows for stable and accurate readings critical for navigation and maintaining flight orientation. The electrical aspect typically involves small electric motors that help maintain the gyro's speed and performance. In addition, the vacuum pump creates a flow of air that supports the gyroscope's rotation, which is essential for its ability to provide reliable directional information. This combination of power sources ensures that gyro instruments are resilient and can operate effectively under a variety of conditions, making them a crucial component in the cockpit for a pilot's situational awareness. Other options do not accurately represent the standard methods of powering gyro instruments, as relying solely on one power source or using an alternative approach like wind energy would not provide the consistent performance required in aviation.
