What is the recommended action for wing flaps during an emergency landing without engine power?

During an emergency landing without engine power, the recommended action for wing flaps is "as required." This approach allows the pilot to assess the specific situation and landing conditions. The primary aim is to maintain control of the aircraft and manage the descent rate effectively.

Using flaps can enhance lift and reduce the stall speed, allowing the pilot to approach the runway at a slower speed, which is beneficial for landing. However, deploying flaps fully, or at any specific setting that may not suit the conditions, could lead to unwanted results such as increased drag or difficulty maintaining control. Factors such as aircraft weight, wind conditions, and the runway's length and surface condition all influence the decision on flap settings.

Adjusting the flaps 'as required' provides flexibility, enabling the pilot to make the best choice based on the circumstances at hand and enhancing the likelihood of a successful landing. This careful consideration is paramount in an emergency situation where every decision can significantly impact the outcome.
