Article 5(2)

PART B NATIONALITY AND REGISTRATION MARKS OF AIRCRAFT REGISTERED IN THE UNITED KINGDOM

1.  The nationality mark of the aircraft shall be the capital letter “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 constructional features of the aircraft and shall always be kept clean and visible.

3.  The nationality and registration marks shall also be inscribed, together with the name and address of the registered owner of the aircraft, on a fire-proof metal plate affixed:

(a) in the case of an aeroplane having an empty weight not exceeding 150kg. either in accordance with paragraph (b) or in a prominent position to the wing; or

(b) in the case of any other aircraft in a prominent position on the fuselage or car or basket, as the case may be, and near to the main entrance to the aircraft.

4.  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:

I.  Position of Marks

(a) Flying Machines and Gliders

(i) Horizontal Surfaces of the Wings or Fuselage (or equivalent structure).

(aa) On aircraft having a fixed wing surface, the marks shall appear on the lower surface of the wing structure, and shall be on the left half of the lower surface of the wing structure unless they extend across the whole surface of both wings. So far as 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.

(bb) On aircraft having no fixed wing surface and when owing to the structure of the aircraft the greatest height reasonably practicable for the marks on the vertical surface of the fuselage (or equivalent structure) is less than 15 centimetres the marks shall also appear on the lower surface of the fuselage on the line of symmetry and shall be placed with the tops of the letters towards the nose.

(ii) Vertical Surfaces of the Tail or Fuselage (or equivalent structure).

The marks shall also be on each side of the aircraft either on the fuselage or on the upper halves of the vertical tail surfaces. On aircraft having a fixed wing surface, the marks, if placed on the fuselage (or equivalent structure), shall be between the horizontal tail surfaces and the wing. When on a single vertical tail surface, the marks shall be on both sides. When there is more than one vertical tail surface, the marks shall be on the outer sides of the outboard vertical tail surfaces.

(b) Airships and Free Balloons

(i) Airships: The marks shall be on each side of the airship. They shall be placed horizontally either on the hull near the maximum cross-section of the airship or on the lower vertical stabiliser.

(ii) Free Balloons: The marks shall be in two places diametrically opposite.

(iii) In the case of all airships and free balloons the side marks shall be so placed as to be visible both from the sides and from the ground.

II.  Size of Marks

(a) Flying Machines and Gliders

(i) Wings: The letters constituting each group of marks shall be of equal height. The height of the letters shall be at least 50 centimetres.

(ii) Fuselage (or equivalent structure) or Vertical Tail Surfaces: The marks on the fuselage (or equivalent structure) shall not interfere with the visible outlines of the fuselage (or equivalent structure). 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. The letters shall be of equal height. The height of the letters constituting each group of marks shall be at least 30 centimetres. Where marks are required to be carried on the lower surface of aircraft having no fixed wing surface the height of the marks shall he at least 50 centimetres.

Provided that where owing to the structure of the aircraft the appropriate height specified in this sub-paragraph (ii) is not reasonably practicable the height of the marks shall be the greatest height reasonably practicable in the circumstances consistent with compliance with Section III of this Part of this Schedule.

(b) Airships and Free Balloons

The letters constituting each group of marks shall be of equal height. The height of the letters shall be at least 50 centimetres.

III.  Width and Spacing of Marks

(a) The width of each letter (except the letter I) and the length of the hyphen between the nationality mark and the registration mark shall be two-thirds of the height of a letter.

(b) The letters and hyphen shall be formed by solid lines and shall be of a colour clearly contrasting with the background on which they appear. Thickness of the lines shall be one-sixth of the height of a letter.

(c) Each letter shall be separated from the letter which it immediately precedes or follows by a space equal to half the width of a letter. A hyphen shall be regarded as a letter for this purpose.

Article 4(8)

PART C AIRCRAFT DEALER'S CERTIFICATE—CONDITIONS

(1) The operator of the aircraft shall be the registered owner of the aircraft, who shall be the holder of an aircraft dealer’s certificate granted under this Order.

(2) The aircraft shall fly only for the purpose of:

(a) testing the aircraft;

(b) demonstrating the aircraft with a view to the sale of that aircraft or of other similar aircraft;

(c) proceeding to or from a place at which the aircraft is to be tested or demonstrated as aforesaid, or overhauled, repaired or modified;

(d) delivering the aircraft to a person who has agreed to buy, lease or sell it; or

(e) proceeding to or from a place for the purpose of storage.

(3) Without prejudice to the provisions of article 35 of this Order the operator of the aircraft shall satisfy himself before the aircraft takes off that the aircraft is in every way fit for the intended flight.

(4) The aircraft shall fly only within the United Kingdom.
