Define the term "gyro" in the context of aviation instruments.

• A. A device that measures altitude
• B. A device that helps maintain orientation by detecting changes in angular velocity
• C. A device that determines speed
• D. A device used for fuel measurement

Answer: (B)

In aviation, the term "gyro" refers to a device that helps maintain orientation by detecting changes in angular velocity. This function is critical for various flight instruments, particularly those related to navigation and attitude control. A gyro operates based on the principles of angular momentum, allowing it to remain in a fixed plane of rotation despite the movement of the aircraft. This capability enables pilots to determine their aircraft's orientation relative to the earth's surface, providing vital information during instrument flight, turning maneuvers, and maintaining level flight. Gyros are essential components of instruments such as the attitude indicator and the heading indicator, where they assist in stabilizing and providing accurate readings as the aircraft maneuvers. This stability is crucial for situational awareness and helps pilots make informed decisions, especially in low-visibility conditions. The ability to detect changes in angular velocity enhances a pilot's control and situational awareness, which is vital for safe flight operations.
