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

The maximum landing gear operating speed for retraction, known as Vlo, is the highest speed at which the landing gear can be retracted safely without risking damage or failure to the landing gear system. For the King Air 350, this speed is determined based on the structural integrity of the landing gear system and the aerodynamic forces acting on the aircraft during the retraction process.

Selecting a retraction speed over the Vlo can result in excessive aerodynamic forces on the gear, potentially leading to malfunctions or structural damage. Therefore, understanding and adhering to this speed is critical for safe operations. The correct answer reflects the established limitation in the aircraft's flight manual, ensuring that operations remain within safe parameters.

The other choices represent speeds either below or above the specified limit, which may not align with the aircraft's designed operational capabilities. By adhering to the correct Vlo, pilots can ensure smoother operations and increased safety throughout the landing phase.
