What is the best rate of climb speed (Vy) for the aircraft?

The best rate of climb speed (Vy) for the Cessna 152 is essential for optimizing the aircraft's performance during climb. Vy is the speed at which the aircraft gains the most altitude in the shortest time and is critical during the initial climb following takeoff.

For the Cessna 152, the best rate of climb speed is typically around 67 KIAS (knots indicated airspeed). At this speed, the aircraft balances lift and drag in such a way that it achieves the maximum vertical speed. Flying at this speed ensures that the aircraft maintains the most efficient climb profile, avoiding unnecessary loss of performance due to either too slow or excessively fast speeds.

While other speeds listed may be operationally safe, they do not maximize the aircraft's climb rate as effectively as 67 KIAS does. Operating at this optimal climb speed ensures that the aircraft can clear obstacles and gain altitude efficiently, which is crucial for safety and operational effectiveness.
