What effect on climb rate can result from an increase in power during a stable climb?

1. Increased climb rate.

2. Reduced climb rate.

3. No effect on climb rate.

4. Loss of control.

The correct answer is: Increased climb rate.

Increasing power during a stable climb results in an increased climb rate. When more power is applied, the aircraft generates additional thrust which can overcome the existing drag and allow the aircraft to gain altitude more rapidly. In a climb, as long as the aircraft is already configured for that maneuver (with the correct speed, attitude, and load factors), adding power enhances the overall performance. This increased thrust helps maintain the necessary airspeed while allowing the aircraft to climb more efficiently. For pilots, understanding this principle is crucial, as it directly impacts flight management and performance optimization. By utilizing power effectively, pilots can confidently adjust their climb rate when needed, such as in situations requiring a faster ascent to avoid terrain or obstacles.
