time period during which the beam moves from the final position of one scan line to the starting position of the subsequent scan line.

Flyback time is commonly associated with rectangular scan patterns and often described in metadata from vendors as such. A typical geometrical primitive for rectangular scans are lines. Flyback time may be considered a specific instance of wait time, however some instruments might still be able to acquire data during flyback time which is why it is defined separately in this artefact.
