Energy height is a measure of an aircraft’s potential energy above a reference point, often the aircraft’s current altitude. It represents the height to which an aircraft could climb if all its kinetic energy (airspeed) were converted into potential energy (altitude) without any thrust or drag. The formula for energy height is as follows:
- is the energy height (typically in meters or feet).
- is the true airspeed (in meters per second or feet per second).
- is the acceleration due to gravity (approximately 9.81 m/s² or 32.2 ft/s²).
