Explanation of terms:
Full Pressure Altitude (V): The altitude at which the supercharger reaches maximum efficiency, resulting in the highest top speed.
Service Ceiling (D): The maximum altitude the aircraft can reach while maintaining a minimum rate of climb.
Continuous Power (a): The maximum speed for long-distance flight without engine damage.
Combat Power (b): Increased performance for a limited duration (usually 30 minutes) during air combat.
