What principle do gyros operate on to maintain orientation?

• A. Magnetic attraction
• B. Angular momentum
• C. Inertia
• D. Electromagnetism

Answer: (B)

Gyros operate on the principle of angular momentum to maintain orientation. When a gyro is set in motion, it maintains a constant angular velocity about its axis of rotation. This property allows the gyro to resist changes to its orientation due to external forces. As a result, it can provide stable reference points for navigation and attitude control in various applications, including aircraft avionics. Angular momentum is a vector quantity that depends on both the mass distribution of the spinning body and its rotational speed. As long as the gyro is spinning, it tends to maintain its position relative to an inertial reference frame, making it invaluable for measuring or maintaining orientation during flight. This principle is utilized in inertial navigation systems to keep track of changes in orientation without relying on external references.
