Nationality and Registration Marks of Aircraft Registered in Singapore
1. The nationality mark of the aircraft shall be the arabic numeral “9” and the roman capital letter “V”, and the registration mark shall be a group of 3 capital letters in roman characters assigned by the Minister 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 in a prominent position, 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 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 and Size of Marks
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 Surface:
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 (d) and (E), 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 (E)) 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 (E)), 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 sub-paragraph (a) marks of the greatest height practicable in the circumstance are required, that height shall be such as is consistent with Section II of this Part.
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 cross-section 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.
II. Width, Spacing and Thickness of Marks
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 marks 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.
The thickness of each letter and hyphen shall be one-sixth of the height of the letters forming the marks.
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.
5. In addition, 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 in a prominent position —
in the case of a balloon, on the basket or envelope; or
in the case of any other aircraft, on the fuselage or car, near the main entrance.
