Why is it critical to manage drag during approach and landing?

Managing drag during approach and landing is crucial for maintaining control of the aircraft and ensuring a safe landing. During these phases of flight, the aircraft must be stabilized at the correct airspeed and descent rate while also being maneuvered for alignment with the runway. Excessive drag can lead to a loss of lift and make it difficult to maintain a safe glideslope, increasing the risk of a stall or uncontrolled descent. By effectively managing drag, pilots can achieve smoother descents, maintain necessary airspeed, and ensure that the aircraft can be controlled throughout the landing process.

The other choices highlight aspects of flight performance but do not specifically address the critical aspect of safety and control during landing. For instance, while reducing fuel consumption is beneficial, it is not the primary concern during the approach and landing phase, which prioritizes safety and control. Similarly, aerodynamic efficiency at high speeds is more relevant to cruising flight rather than landing, and improving visibility during descent, though important, does not directly correlate with drag management objectives during landing.
