The Time of Flight () in a climb refers to the duration it takes for an aircraft to ascend from one altitude to another during a climbing phase. It represents the elapsed time during the climb, providing information on how long the aircraft spends ascending from a starting altitude to a final altitude. The formula to calculate Time of Flight in a climb is given by:
where:
- is the time of flight,
- is the change in altitude,
- is the true airspeed,
- is the climb angle.
