Article 3 Aircraft to be registered
Subject to paragraph (2) an aircraft shall not fly in or over the United Kingdom unless it is registered in:

some other country in relation to which there is in force an agreement between Her Majesty’s Government in the United Kingdom and the Government of that country which makes provision for the flight over the United Kingdom of aircraft registered in that country.
A glider may fly unregistered, and shall be deemed to be registered in the United Kingdom for the purposes of articles 14, 15, 21 and 43 of this Order, on any flight which:
begins and ends in the United Kingdom without passing over any other country, and
is not for the purpose of public transport or aerial work other than aerial work which consists of the giving of instruction in flying or the conducting of flying tests in a glider owned or operated by a flying club of which the person giving the instruction or conducting the test and the person receiving the instruction or undergoing the test are both members.
Any aircraft may fly unregistered on any flight which:
begins and ends in the United Kingdom without passing over any other country, and
is in accordance with the ‘B Conditions’ set forth in Part A of Schedule 3 to this Order.
Paragraph (1) shall not apply to any kite or captive balloon.
If an aircraft flies over the United Kingdom in contravention of paragraph (1) in such manner or circumstances that if the aircraft had been registered in the United Kingdom an offence against this Order or any regulations made thereunder would have been committed, the like offence shall be deemed to have been committed in respect of that aircraft.
