When comparing the angle of climb with flaps extended to that with flaps retracted, what is typically observed?

In the context of aircraft performance, when comparing the angle of climb with flaps extended versus flaps retracted, it is generally observed that the angle of climb is smaller with the flaps extended. This phenomenon occurs because extending the flaps increases the lift coefficient at lower speeds, which may initially seem beneficial for climbing. However, this increase in lift is accompanied by a substantial increase in drag, which hampers the aircraft's overall performance.

With the flaps extended, the additional drag reduces the aircraft's climb rate and subsequently affects the angle of climb negatively, even though the aircraft may take off at a lower speed. Essentially, while the extended flaps may provide more lift at lower speeds, the increased drag predominates, resulting in a smaller angle of climb compared to when the flaps are retracted.

This aspect of aerodynamics highlights the trade-offs pilots must consider regarding lift, drag, and climb performance during various phases of flight.
