During approach for landing under clear skies with convective turbulence, what action should be taken to avoid stalling?

Increasing the approach airspeed slightly is an effective strategy to avoid stalling during landing, particularly in conditions of convective turbulence. Convective turbulence can cause sudden changes in air movement and lift, which can be more challenging to manage at lower airspeeds. By increasing the approach airspeed, the pilot enhances the margin above stall speed, allowing for greater responsiveness to turbulence and reducing the risk of stalling the aircraft.

Maintaining a higher airspeed during approach helps ensure that the aircraft remains well within its aerodynamic limits, making it easier to counteract the effects of turbulence that might momentarily disrupt lift or induce nose-up attitudes. This approach can provide increased control and stability, allowing the pilot to navigate through potentially rough air with more confidence.

The other options may not provide the same level of effectiveness in mitigating the risk of stalling in turbulent conditions. For instance, gradually decreasing altitude or using flaps to reduce speed does not necessarily address the risk of a stall as effectively as adjusting the airspeed. Maintaining current airspeed could also expose the aircraft to stalling if it is already close to the stall margin, particularly in turbulent conditions where additional lift may be temporarily lost.
