During what phase of flight is controlling excessive speed crucial?

1. Takeoff and climb.

2. Descent and landing.

3. Cruise flight.

4. Taxiing on the ground.

The correct answer is: Descent and landing.

Controlling excessive speed is crucial during the descent and landing phase of flight because this is when precise speed management is essential for safe and effective operation. During descent, pilots must ensure that the aircraft maintains a speed that is not excessively high, as this can lead to a longer landing rollout and potential control difficulties upon touchdown. As the aircraft descends towards the runway, maintaining an optimal approach speed is critical. An excessive speed can result in increased landing distances, challenges in staying within the runway environment, or difficulty in executing a safe go-around if necessary. Additionally, flying at excessive speeds can reduce the effectiveness of control surfaces at lower airspeeds, greatly affecting the handling characteristics of the aircraft during the critical moments approaching landing. While speed control is important in all phases of flight, it is particularly emphasized during descent and landing when pilots need to stabilize their approach and ensure they are configured properly for touchdown. Addressing excessive speed during these phases directly impacts safety and operational efficiency.
