According to typical airspeed indicator markings, what is the maximum speed with flaps fully extended?

The maximum speed with flaps fully extended is a crucial specification that pilots must understand for safe aircraft operation during approach and landing phases. Typically, this speed is indicated as Vfe on the airspeed indicator and represents the maximum permissible speed to safely use the flaps without risking structural damage or loss of control.

In this case, the correct answer indicates that the maximum speed with flaps fully extended is 91 knots. This speed is crucial for maintaining control of the aircraft during slow flight with flaps extended, ensuring that the aircraft remains within safe operational limits. Exceeding this speed could lead to adverse aerodynamic effects or a potential increase in drag that could compromise the aircraft's performance during landing or approach.

Understanding this limitation is essential, as each aircraft model might have different Vfe values based on the design and manufacture. Pilots must refer to the Aircraft Flight Manual or Pilot's Operating Handbook for the specific maximum flaps extended speed for their aircraft. The knowledge of this airspeed is vital for maintaining safety and effectiveness during flight maneuvers.
