Retour en vol in French. This term describes a counter mechanism that can be stopped and reset to zero by pressing the pushbutton once. On its release, the hand or hands move forward once again. This device allows a plane or ship to change course according to a preset schedule. Once a sequence is complete, the next sequence is started by pressing the pushbutton.
