The rate of change of altitude with respect to time during the climb phase, often referred to as the climb rate or rate of climb (ROC), is a fundamental parameter in flight mechanics. It represents how quickly an aircraft is ascending or descending vertically and is typically expressed in units such as feet per minute (ft/min) or meters per second (m/s).
- : This represents the climb speed, which is the rate of change of altitude with respect to time during the climb phase. It is typically measured in units like feet per minute (ft/min) or meters per second (m/s).
- : This is the initial true airspeed of the aircraft before it begins its climb. True airspeed (�) is the actual airspeed of the aircraft through the air.
- : This usually represents the climb rate. It’s the rate at which the aircraft is ascending vertically and is typically expressed in feet per minute (ft/min) or meters per second (m/s).
- : The flight path angle, which is the angle between the aircraft’s flight path and the horizontal plane, usually measured in radians.
