Flight crew duty assignment
132.—(1)  For every flight of a relevant aircraft, the AOC holder must designate —
(a)a flight crew member as the pilot-in-command;
(b)the number of persons required as additional flight crew members to augment the minimum crew specified in the aircraft’s flight manual due to —
(i)the type of aircraft operated;
(ii)the type of operation to be performed; and
(iii)the duration of the flight.
(2)  An AOC holder must assign each flight crew member to the functions that the flight crew member is required to carry out in the event of an aircraft emergency.
(3)  For every flight of a relevant aircraft, the AOC holder must ensure that the assigned flight crew includes —
(a)if the aircraft has a separate flight engineer’s station, at least one flight engineer who is especially assigned to that station; and
(b)if the aircraft is likely to perform an operation where navigation necessary for the safe conduct of the flight cannot be adequately accomplished by the pilots from the pilot station, at least one flight crew member who holds a flight navigator licence.
(4)  Paragraph (3)(a) does not apply when the duties associated with the separate flight engineer’s station can be adequately performed by another flight crew member holding a flight engineer licence without interference with that flight crew member’s regular duties.
