Assigning Crew to flights is possible by scheduling them in Crew Duties. If a duty, by definition, should be included in planning and assigned to an aircraft (by type or registration), a crew will automatically be scheduled on a flight, as per duty.
There are 2 following scenarios if changes are made to the flight:
If there are no duties scheduled and the crew are already assigned to a flight, changing aircraft type will remove the crew from this flight. Changing the type of an aircraft back to the previously assigned one, will re-assign the same crew.
