Question 152General Subjects - Assistant Engineer

The correct answer is C) Promptness. Promptness refers to how rapidly a speed control governor will complete a corrective action in response to a load change. The speed governor needs to quickly adjust the engine's throttle to maintain a consistent engine speed, and the promptness of this response is a key factor in the governor's performance. The other options are not as directly relevant to this concept. Sensitivity refers to the governor's ability to detect small changes in speed, power is a measure of the governor's ability to overcome the load, and dead band is the range of speed variation the governor allows before making a correction.
