  "text": "(This note is not part of the Order)\nThis Order further amends the Air Navigation (No. 2) Order 1995. In addition to minor and drafting amendments, the following changes are made:\n1 Responsibilities in respect of airworthiness, radio equipment, radio licensing and flight crew licensing in connection with an aircraft may be discharged by the State of the operator of that aircraft rather than its State of registration in certain circumstances pursuant to Article 83 bis of the Chicago Convention (article 3).\n2 An airborne collision avoidance system which meets specified requirements must be carried by an aircraft flying in specified airspace within the United Kingdom (article 4).\n3 A flying display is defined. A person organising a flying display is termed a flying display director and must obtain permission of the Civil Aviation Authority. A pilot in a flying display must hold an appropriate pilot display authorisation granted by the Civil Aviation Authority or by the competent authority of a Member State of the Joint Aviation Authorities (article 5).\n4 Flight time, for the purpose of flight time limitation schemes, now includes time spent as the member of the crew of a military aircraft except for small aircraft operated under the auspices of the Royal Air Force Air Cadet Organisation (article 6).\n5 (a) If a flight information service officer does not provide a service at a particular aerodrome or area control centre throughout a period of 90 days, the licence shall cease to be valid for that aerodrome or area control centre (article 7(2)).\n(b) A flight information service includes the granting or refusing of permission to an aircraft to taxi on the apron or the manoeuvring area of an aerodrome or to a vehicle or person to go on the manoeuvring area of an aerodrome (article 7(8)).\n6 A serious incident is required to be notified to the Chief Inspector of Air Accidents and is not a reportable occurrence under the Order (article 8).",
