For the best rate of climb (Vy), what is the recommended speed?

The recommended speed for achieving the best rate of climb (Vy) is tied to the specific performance characteristics of the aircraft. Vy is defined as the speed at which an aircraft attains the greatest altitude gain in the shortest amount of time. This speed is vital in scenarios such as takeoff and initial climb, when altitude must be gained quickly for safety or operational requirements.

A speed of 130 knots is often optimal for many light aircraft operating under conditions where altitude gain is essential without sacrificing safety. This speed typically allows for the best balance between climb rate and power management. Ensuring that the aircraft operates at this speed helps maintain efficient airflow over the wings, maximizing lift while minimizing drag.

In contrast, other speeds, such as 115, 120, or 140 knots, may not yield the same climb efficiency. Speeds that are too low can result in inadequate climb performance or increased vulnerability to stall conditions. Conversely, speeds that are excessively high may increase drag, thereby decreasing the climb rate. Therefore, the choice of 130 knots as the best rate of climb speed factors in aerodynamic efficiency and engine performance, aligning perfectly with standard operational practices.
