Which speed indicates the maximum speed for gear extension (Vlo)?

The maximum speed for gear extension, known as Vlo, is a critical airspeed during flight as it indicates the highest speed at which the landing gear can be safely deployed. In this context, the correct answer reflects the operational limitations that are specified by the aircraft manufacturer.

The provided value of 140 KIAS for Vlo means that the gear should only be extended when the aircraft is flying at or below this speed to ensure that the landing gear mechanisms function correctly without excessive aerodynamic forces that could damage the gear or the aircraft itself. Exceeding this speed might cause issues such as incomplete gear extension or mechanical failure due to the aerodynamic loads acting on the gear components.

Understanding Vlo and adhering to the specified limitations is essential for safe aircraft operation. It allows pilots to manage the aircraft's configuration for landing effectively, ensuring that the gear extends reliably and reduces the risk of complications during the approach phase.
