What is the VLE speed, which is important for aircraft performance?

The VLE speed, or maximum landing gear extended speed, is crucial for ensuring that the landing gear can safely be deployed and that the aircraft remains controllable while doing so. In this context, the correct answer of 250 KIAS (Knots Indicated Airspeed) reflects common regulatory standards that define operational limits for aircraft during flight operations.

At 250 KIAS, pilots can extend the landing gear without risking structural damage or control difficulties, as this speed typically falls within the recommended operating range for many commercial aircraft. This speed is significant during the approach and landing phases, providing a safety margin and ensuring the aircraft is operating within its specified performance parameters.

Understanding VLE speed is essential for pilots when planning approaches, as exceeding this speed can lead to complications, such as difficulty in deploying the gear or increased aerodynamic resistance. Therefore, 250 KIAS is a standard choice for VLE in many aircraft systems, facilitating safe operations during critical flight phases.
