What is the transition airspeed for the alternative climb schedule after 10,000 feet?

The transition airspeed for the alternative climb schedule after 10,000 feet is set at 320 Knots Indicated Airspeed (KIAS). This speed is established to optimize climb performance and efficiency at higher altitudes.

The choice of 320 KIAS aligns with standard regulatory guidelines that provide a safe and effective speed for aircraft as they ascend through varying airspace. It incorporates considerations such as aircraft handling characteristics, engine performance, and aerodynamic efficiency, ensuring that pilots can maintain control of the aircraft while avoiding excessive speed that could create safety risks.

Furthermore, this speed allows for a smoother transition to cruising altitude and trajectory as the aircraft approaches the designated operational levels, minimizing potential turbulence and maximizing fuel efficiency. It provides a standardized limit that can be easily communicated and practiced among pilots and air traffic management systems.
