Excess power in aviation refers to the surplus power available to an aircraft beyond what is required for level flight. It is a crucial parameter for determining an aircraft’s ability to climb, accelerate, or execute maneuvers. Positive excess power indicates the capacity for climbing, while negative values suggest a power deficiency, leading to descent. The formula to calculate Excess power is as follows:
Where:
- is the excess power in watts
- stands for the Rate of Climb in m/s
- is the weight of the aircraft in N.
