What is the maximum landing gear operating speed (Vlo)?

The maximum landing gear operating speed, often referred to as Vlo, is a critical parameter for aircraft operation that denotes the highest speed at which the landing gear can be safely deployed or retracted. Selecting 180 knots as the correct answer indicates that at this speed, the aircraft is designed to successfully extend or retract its landing gear without compromising structural integrity or safe operation.

Aircraft manufacturers establish this parameter based on extensive testing and design considerations. Operating above this speed can lead to risks such as gear malfunction, increased aerodynamic loading, or structural failure of the landing gear mechanism. Therefore, understanding and adhering to this speed limit is vital for maintaining safety during the landing gear operation phase of flight.
