Final answer:
When using the gyro-pilot for steering, the control that is adjusted to compensate for varying sea conditions is the Pitch sensitivity.
Step-by-step explanation:
When the gyro-pilot is used for steering, the control that is adjusted to compensate for varying sea conditions is the Pitch sensitivity.
The gyro-pilot is a system that uses gyroscopes to maintain a steady course. It adjusts the control surfaces of an aircraft or a ship to counteract changes in the vessel's pitch, roll, and yaw.
Pitch sensitivity refers to the responsiveness of the gyro-pilot to changes in pitch, which is the up and down motion of a vessel. By adjusting the pitch sensitivity, the gyro-pilot can compensate for varying sea conditions and keep the vessel on a steady course.
