What is VY defined as?

VY, or Vy, refers to the speed for the best rate of climb. This speed allows an aircraft to gain the most altitude in the least amount of time, which is a crucial factor during takeoff or in situations where a quick ascent is necessary. Obtaining the best rate of climb is important for avoiding obstacles and ensuring safety during flight operations.

When flying at VY, the aircraft maintains an optimal balance of lift and drag, which maximizes the climb performance. This speed is influenced by factors such as weight, altitude, and atmospheric conditions, making it vital for pilots to be familiar with the specific VY for their aircraft model under various scenarios.

Understanding VY is essential for effective flight planning and execution, particularly in situations where altitude gain is imperative, and it underscores the importance of performance figures in operational flying.
