The Air Navigation Order 1989[^f00002] shall be amended as follows:

(2) Before 1st November 1992 the marks to be borne by aircraft registered in the United Kingdom shall comply with Part B1 or Part B2 of Schedule 1 to this Order. On and after 1st November 1992 the marks to be borne by aircraft registered in the United Kingdom shall comply with Part B2 of Schedule 1 to this Order.

(b) a balloon flying on a private flight;

  • from the moment when, after the embarkation of its passengers for the purpose of taking off, it first moves until after it has taken off, and before it lands until it comes to rest for the purpose of the disembarkation of its passengers, and whenever by reason of turbulent air or any emergency occurring during the flight he considers the precaution necessary:

(39A) (1) An aircraft registered in the United Kingdom shall not fly in controlled airspace notified for the purposes of this paragraph of this article as an area navigation route or area unless— (a) it is equipped with area navigation equipment which is approved by the Authority in relation to the purpose for which it is to be used, and which is installed and maintained in a manner approved by the Authority; and (b) the said equipment is capable of being operated so as to enable the aircraft to maintain the navigation accuracy notified in respect of the airspace in which the aircraft is flying, and it is so operated. (2) An aircraft registered in the United Kingdom shall not, when flying in controlled airspace notified for the purposes of this paragraph of this article, not being an area navigation route or area, be navigated by means of area navigation equipment unless— (a) the said equipment is approved by the Authority in relation to the purpose for which it is to be used, and is installed and maintained in a manner approved by the Authority; and (b) the said equipment is capable of being operated so as to enable the aircraft to maintain the navigation accuracy notified in respect of the airspace in which the aircraft is flying, and it is so operated.

(3A) The specified minimum weather provisions shall be as follows— (a) outside airspace notified for the purposes of Schedule 8 to this Order— (i) an aircraft flying above 3000 ft. above mean sea level shall remain at least 1800 metres horizontally and 1000 ft. vertically away from cloud and in a flight visibility of at least 10 km; (ii) an aircraft other than a helicopter flying at or below 3000 ft. above mean sea level shall remain at least 1800 metres horizontally and 1000 ft. vertically away from cloud and in a flight visibility of at least 5 km: Provided that this sub-paragraph shall be deemed to be complied with if the aircraft is flown at a speed which according to its airspeed indicator is 140 knots or less and remains clear of cloud, in sight of the surface and in a flight visibility of at least 1800 metres; (iii) a helicopter flying at or below 3000 ft. above mean sea level shall remain clear of cloud and in sight of the surface or at least 1800 metres horizontally and 1000 ft. vertically away from cloud and in a flight visibility of at least 5km. (b) within airspace notified for the purposes of Schedule 8 to this Order an aircraft shall remain at least 1800 metres horizontally and 1000 ft. vertically away from cloud and in a flight visibility of at least 10 km: Provided that in a control zone within such airspace, in the case of a special VFR flight the aircraft shall be flown in accordance with any instructions given by the appropriate air traffic control unit.

(1) The nationality mark of the aircraft shall be the capital letters “G” in Roman character and the registration mark shall be a group of four capital letters in Roman character assigned by the Authority on the registration of the aircraft. The letters shall be without ornamentation and a hyphen shall be placed between the nationality mark and the registration mark. (2) The nationality and registration marks shall be displayed to the best advantage, taking into consideration the construction features of the aircraft and shall always be kept clean and visible. (3) The letters constituting each group of marks shall be of equal height and they, and the hyphen, shall be of a single colour which shall clearly contrast with the background on which they appear. (4) The nationality and registration marks shall also be inscribed on a fire-proof metal plate affixed in a prominent position— (a) in the case of a microlight aeroplane, either in accordance with subparagraph (c) of this paragraph or on the wing; (b) in the case of a balloon, on the basket or envelope; or (c) in the case of any other aircraft on the fuselage or car, as the case may be. (5) The nationality and registration marks shall be painted on the aircraft or shall be affixed thereto by any other means ensuring a similar degree of permanence in the following manner: 1. Heavier-than-air Aircraft (excluding kites) Horizontal Surfaces of the Wings— On aircraft having a fixed wing surface, the marks shall appear on the lower surface of the wing structure, and shall be on the port wing unless they extend across the whole surface of both wings. So far as is possible the marks shall be located equidistant from the leading and trailing edges of the wings. The tops of the letters shall be towards the leading edge of the wing. The height of the letters shall be at least 50 centimetres: Provided that if the wings are not large enough for the marks to be 50 centimetres in height, marks of the greatest height practicable in the circumstances shall be displayed. Fuselage (or equivalent structure) and Vertical Tail Surfaces— The marks shall also appear either— on each side of the fuselage (or equivalent structure), and shall, in the case of fixed wing aircraft, be located between the wings and the horizontal tail surface; or on the vertical tail surfaces. When located on a single vertical tail surface, the marks shall appear on both sides. When located on multi-vertical tail surfaces the marks shall appear on the outboard sides of the outer surfaces. Subject to sub-paragraphs (dd) and (ee) below, the height of the letters constituting each group of marks shall be at least 30 centimetres. If one of the surfaces authorised for displaying the required marks is large enough for those marks to be 30 centimetres in height (whilst complying with sub-paragraph (ee) below) and the other is not, marks of 30 centimetres in height shall be placed on the largest authorised surface. If neither surface is large enough for marks of 30 centimetres in height (whilst complying with sub-paragraph (ee) below), marks of the greatest height practicable in the circumstances shall be displayed on the larger of the two surfaces. The marks on the vertical tail surfaces shall be such as to leave a margin of at least 5 centimetres along each side of the vertical tail surface. On rotary wing aircraft where owing to the structure of the aircraft the greatest height practicable for the marks on the sides of the fuselage (or equivalent structure) is less than 30 centimetres the marks shall also appear on the lower surface of the fuselage as close to the line of symmetry as is practicable and shall be placed with the tops of the letters towards the nose. The height of the letters constituting each group of marks shall be at least 50 centimetres: Provided that if the lower surface of the fuselage is not large enough for the marks to be of 50 centimetres in height, marks of the greatest height practicable in the circumstances shall be displayed. Wherever in this sub-paragraph (a) marks of the greatest height practicable in the circumstances are required, that height shall be such as is consistent with compliance with Section II of this Part of this Schedule. 2. Airships and Free Balloons Airships: The marks shall be placed on each side of the airship. They shall be placed horizontally either on the hull near the maximum crosssection of the airship or on the lower vertical stabiliser. Free Balloons: The marks shall be in two places on diametrically opposite sides of the balloon. In the case of both airships and free balloons the side marks shall be so placed as to be visible both from the sides and from the ground. The height of the letters shall be at least 50 centimetres. 1. For the purposes of this Section “a standard letter” shall mean any letter other than the letters I, M and W. The width of each standard letter and the length of the hyphen between the nationality mark and the registration mark shall be two-thirds of the height of a letter. The width of the letters M and W shall be neither less than two-thirds of their height nor more than their height. The width of the letter I shall be one-sixth of the height of the letters forming the marks. 2. The thickness of each letter and hyphen shall be one-sixth of the height of the letters forming the marks. 3. Each letter and hyphen shall be separated from the letter or hyphen which it immediately precedes or follows, by a space equal to either one-quarter or one-half of the width of a standard letter. Each such space shall be equal to every other such space within the marks.

(b) when flying within controlled airspace notified for the purposes of this subparagraph

(b) when flying within airspace notified for the purposes of this sub-paragraph

(bb) when any passenger is carried and the aeroplane is flying either above 3000ft. above mean sea level in conditions such that it cannot remain at least 1800 metres horizontally and 1000 ft. vertically away from cloud and in a flight visibility of at least 10km or at or below 3000ft. above mean sea level in a flight visibility of less than 5km;

(e) he shall not unless his licence includes an instrument rating (aeroplanes) fly as pilot in command or co-pilot of such an aeroplane flying in airspace notified for the purposes of this Schedule— (i) in conditions such that he cannot comply with the specified minimum weather provisions; or (ii) in circumstances which require compliance with the Instrument Flight Rules.

(bb) when any passenger is carried and the aeroplane is flying either above 3000ft. above mean sea level in conditions such that it cannot remain at least 1800 metres horizontally and 1000ft. vertically away from cloud and in a flight visibility of at least 10km or at or below 3000ft. above mean sea level in a flight visibility of less than 5km;

(h) he shall not unless his licence includes an instrument rating (aeroplanes) fly as pilot in command or co-pilot of such an aeroplane flying in airspace notified for the purposes of this Schedule— (i) in conditions such that he cannot comply with the specified minimum weather provisions; or (ii) in circumstances which require compliance with the Instrument Flight Rules.

(f) he shall not unless his licence includes an instrument rating (aeroplanes) fly as pilot in command or co-pilot of such an aeroplane flying in airspace notified for the purposes of this Schedule— (i) in conditions such that he cannot comply with the specified minimum weather provisions; or (ii) in circumstances which require compliance with the Instrument Flight Rules.

(e) he shall not unless his licence includes an instrument rating (helicopters) fly as pilot in command or co-pilot of such a helicopter flying in airspace notified for the purposes of this Schedule— (i) in conditions such that he cannot comply with the specified minimum weather provisions; or (ii) in circumstances which require compliance with the Instrument Flight Rules.

(f) he shall not unless his licence includes an instrument rating (helicopters) fly as pilot in command or co-pilot of such a helicopter flying in airspace notified for the purposes of this Schedule— (i) in conditions such that he cannot comply with the specified minimum weather provisions; or (ii) in circumstances which require compliance with the Instrument Flight Rules.

Explanatory note

(This note is not part of the Order)

This Order amends the Air Navigation Order 1989.

The principal changes are:

The meanings of controlled airspace, control areas and control zones are redefined accordingly.

The flight crew licensing and equipment requirements which applied in what was previously controlled airspace will continue to apply in substantially the same form in the same airspace.

Imperial measurements have been converted into metric measurements in certain articles.

New criteria are introduced for flight in visual meteorological conditions.

(Article 2(4), (14), (15), (17), (18), (19), (20), (22), (25), (26), (31), (32), (35), (36), (37) and (39)—(55)).

Apart from such area navigation routes or areas within which the use of approved area navigation equipment is mandatory, certain other routes and areas within controlled airspace will be notified for area navigation purposes. Within this additional notified airspace it is not mandatory for an aircraft to use area navigation equipment. However, if it is navigated by means of area navigation equipment then that equipment must be of an approved type, installed in an approved manner.

The approval of equipment, installation and maintenance must be in accordance with the law of the country in which the aircraft is registered. In the case of UK registered aircraft the required approvals must be sought from the Civil Aviation Authority (article 2(9) and (16)).
