Detailed Description

Findlet to adjust the flight time of tracks relative to the flight time zero.

The flight time of tracks is currently only adjusted in the start trajectories of each given track and the time which is need to reach the flight time zero location with the speed of flight on the curved trajectory is set as the flight time.
