In flight mechanics, “climb speed” refers to the rate at which an aircraft gains altitude vertically, often expressed in units of velocity (such as meters per second or feet per minute). Climb speed is a key parameter that describes the aircraft’s ability to ascend or descend within a given time frame. It’s an important concept in aviation as it relates to the aircraft’s performance and efficiency in climbing to higher altitudes or descending to lower altitudes.
- represents the climb speed or rate of climb.
- represents the true airspeed of the aircraft.
- (gamma) is the flight path angle, which is the angle between the aircraft’s velocity vector and the horizontal plane.
