Regulation 4 Engagement with right to transfer to the reserve, on notice (the notice engagement)

A person who has reached the age of 16 years may be enlisted in the Royal Air Force for a term (which may include service in the reserve) of not less than 3 years’ nor more than 9 years’ air force service from the relevant date with the right to be transferred to the reserve on or at any time after the expiration of 3 years after the end of his period of training, such right being exercisable in accordance with regulation 10 and subject to regulation 12.

A person enlisted pursuant to this regulation shall retain the right conferred thereby to transfer to the reserve notwithstanding that his term is extended under regulation 14(1).

A person enlisted pursuant to this regulation may apply by notice in writing to his commanding officer to be treated as if he had been enlisted pursuant to regulation 3 for a term equal in length to the term for which he was enlisted under this regulation; and, if the competent air force authority approves his application, he shall be so treated from the date on which his application is approved.
