The availability of crew consists of a recurring pattern that repeats automatically. This is called the standard rota. That standard pattern can be overwritten by one-off exceptions. The exception bookings are indicated with a red border.
In th example below we have 4 consecutive blocks:
- 13 - 17: Available by exception
- 17 - 19: Unavailable as per standard rota
- 19 - 21: Unavailable by exception
- 21 - 24: Available as per standard rota
