What is the maximum speed for Vfe5?

The maximum speed for Vfe5, which is the maximum flap extended speed for flaps fully extended to the 5-degree position, is critical for safe aircraft operation during approach and landing phases. This speed ensures that the aircraft can maintain control and stability while the flaps are deployed, facilitating a safer descent and landing trajectory.

In this case, the correct maximum speed is 180 KIAS. This value is established based on the aircraft's design limitations and the aerodynamic factors involved when flying with the flaps extended. Operating at or below this speed allows pilots to comply with safety protocols, ensuring the aircraft remains within its operational envelope while reducing the risk of stalling or other aerodynamic issues associated with higher speeds.

The other provided speeds are above the prescribed limit for Vfe5, and flying at those speeds with flaps extended could jeopardize the aircraft's performance and safety. Keeping the aircraft within the limits specified by the manufacturer is vital to maintaining its airworthiness and ensuring the safety of all on board.
