Which device measures angular velocity to help stabilize aircraft?

• A. Gyroscope
• B. Accelerometer
• C. Magnetometer
• D. Barometer

Answer: (A)

Sensing how fast the aircraft is rotating around each axis is essential for stabilization. A gyroscope provides angular velocity readings, giving you the rotation rates (roll, pitch, and yaw) in real time. Those rate signals feed the flight controller so it can apply corrective motor commands to damp disturbances and keep the aircraft steady. An accelerometer measures linear acceleration and can help estimate tilt by sensing gravity, but it does not report rotation speed. A magnetometer detects the direction of Earth's magnetic field to aid with heading, not rotation rate. A barometer measures air pressure to estimate altitude, not rotation. Therefore, the device that measures angular velocity for stabilization is the gyroscope.
