What is the primary reason for increasing airspeed during the approach to a landing in turbulence?

Increasing airspeed during the approach to landing in turbulence is primarily done to attain more positive control of the aircraft. When flying in turbulent conditions, a higher airspeed offers several advantages.

In turbulence, the aircraft is subject to sudden and unpredictable changes in airflow, which can lead to variations in lift and loss of control if the aircraft is too slow. By maintaining a higher airspeed, pilots can ensure that the aircraft remains in a stable flight envelope, which enhances overall control responsiveness. This additional margin helps counteract the effects of turbulence, reducing the risk of stalling or experiencing adverse yawing moments.

Additionally, a higher airspeed can provide better handling characteristics in turbulent air, allowing the pilots to make both minor and major adjustments more effectively. This is particularly important during the critical phases of flight, such as landing, where precision and control are crucial for a safe descent and touchdown.
