What is the maximum speed with gear extended (Vle) in KIAS?

The maximum speed with gears extended, known as Vle, is a critical parameter in multi-engine aircraft operation. This speed is important for ensuring that the landing gear can remain extended without the risk of damage or aerodynamic complications. In this case, the choice of 140 KIAS reflects a common threshold for many multi-engine aircraft designs, indicating that the aircraft can safely operate with the landing gear extended up to this speed.

Knowing Vle helps pilots manage their speed during approaches and landings, ensuring they do not exceed this limit, which could lead to structural failure of the landing gear or loss of control due to aerodynamic effects. Each aircraft has its specific Vle listed in the Pilot Operating Handbook (POH), which must always be referred to for accurate operational limits.

Understanding Vle is an essential part of multi-engine operational safety, as it impacts the overall performance and handling characteristics of the aircraft during critical flight phases.
