What component is the sensing device in an electromechanical autopilot system?

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

Answer: (A)

The sensing device in an electromechanical autopilot is the gyro because stabilizing the aircraft’s attitude requires measuring how the airplane is rotating. A gyroscope senses angular rates (roll, pitch, and yaw), and the autopilot uses that information to compare actual motion with the commanded attitude and drive control surfaces to correct any error. An accelerometer measures linear acceleration, which doesn’t directly tell you the aircraft’s orientation on its own. A magnetometer provides heading relative to the Earth's magnetic field and isn’t the primary attitude sensor in these systems. A barometer measures altitude, not orientation or rotational motion. So the gyro is the correct sensing device for maintaining and correcting attitude in an electromechanical autopilot.
