  "text": "(This note is not part of the Order)\nThis Order consolidates the Air Navigation (No. 2) Order 1995, as amended. In addition to some minor drafting amendments the following new provisions are added.\n1 An aircraft may not fly within airspace notified as reduced vertical separation minimum airspace unless it is equipped with appropriate height keeping equipment which, in the case of United Kingdom registered aircraft, must be installed, maintained and operated in a manner approved by the Civil Aviation Authority (articles 48, 49 and 129).\n2 Aeroplanes registered in the United Kingdom that are powered by one or more turbine jets or by one or more turbine propeller engines must be equipped with a terrain awareness and warning system:\n(a) by 1 January 2001 if first issued with a certificate of airworthiness on or after that date, operating for the purpose of public transport, and weighing more than 15,000 kg or certified to carry more than 30 passengers;\n(b) by 1 October 2001 if weighing more than 5,700 kg or certified to carry more than 9 passengers, whether or not flying for the purpose of public transport if not equipped with a ground proximity warning system before 1 April 2000;\n(c) by 1 January 2005 if weighing more than 5,700 kg or certified to carry more than 9 passengers, whether or not operating for the purpose of public transport if equipped with a ground proximity warning system before 1 April 2000.\nAeroplanes operated under and in accordance with the terms of a police air operator’s certificate are not affected by this requirement.\n(Schedule 4).\n3 A helicopter registered in the United Kingdom and weighing 5,700 kg or less which is flying for the purpose of public transport either in instrument meteorological conditions or at night with visual ground reference, must carry either two pilots or one pilot and an autopilot. A helicopter flying for the purpose of public transport at night with visual ground reference must be appropriately equipped depending on whether it is flying with one or two pilots. Every pilot included in the flight crew of a helicopter flying for the purpose of public transport whose licence does not include an instrument rating but who is intended to fly at night under visual flight conditions must be tested by the operator as to his competence (article 20 and Schedules 4 and 10).\n4 All provisions other than Articles 27(2), 122 and 134 rely on the domestic powers.",
