What is the consequence of operating the aircraft at Vfe?

Operating the aircraft at Vfe, which is the maximum flap extended speed, has significant implications for the safety and performance of the aircraft. When the aircraft is flown at speeds exceeding Vfe with the flaps extended, there is a potential risk of structural damage. The flaps are designed to enhance lift and increase drag at specific speeds, and exceeding the maximum allowed speed while they are deployed can result in excessive aerodynamic loads.

These loads can lead not only to deformation of the flaps themselves but also to failure of the flap mechanisms or even damage to the wing structure. This sort of stress on the aircraft can compromise its integrity and safety, emphasizing why it is crucial to adhere strictly to Vfe limitations during flight operations.

Other options, while they might involve issues related to flight safety or performance, do not directly address the primary concern of structural integrity and the risk it poses when operating beyond Vfe thresholds.
