Article 44 Members of flight crew - requirement for licenceI1
United Kingdom
A person must not act as a member of the flight crew of an aircraft registered in the Territory without holding an appropriate licence granted or rendered valid under this Order.
An appropriate licence for the purposes of this Part means a licence which entitles the holder to perform the functions being undertaken in relation to the aircraft concerned on the particular flight.
The holder of a licence, endorsed to the effect that the holder does not satisfy in full the relevant international standard and which has been granted or rendered valid under this Order, must not act as a member of the flight crew of an aircraft registered in the Territory in or over the territory of a Contracting State other than the Territory except in accordance with permission granted by the competent authority of that State.
The holder of a licence granted or rendered valid under the law of a Contracting State other than the Territory, being a licence endorsed as provided in paragraph (3), must not act as a member of the flight crew of any aircraft in or over the Territory except in accordance with permission granted by the Governor, whether or not the licence is rendered valid under this Order.
