Rule 30 of the Aircraft Rules, 1937 empowers the Central Government to register an aircraft and to grant a Certificate of Registration in respect thereof.
What is Nationality or Common Mark?

What is Registration Marks ?
A group of characters affixed on aircraft surface following Nationality marks to identify a particular aircraft.
Registration markings shall not be allotted which might be confused with International Code of Signals, especially:
- Registration beginning with the letter ‘Q’
- Registrations ‘SOS‘, ‘XXX’, ‘PAN’ and ‘TTT’
Fixation of Nationality and Registration Marking
The nationality marks to be affixed on Indian registered aircraft would be capital letters ”VT” in Roman character and registration marking would consist of a group of three letters in Roman Character as assigned by the Director General of Civil Aviation. A hyphen must be placed between the nationality and registration marks. 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. The marks shall be kept clean and visible at all times.
Location of Nationality or Common Mark and Registration Marks
(i) Lighter-than-air aircraft:
a) Airships: The marks on an airship shall appear either on the hull, or on the stabilizer surfaces. Where the marks appear on the hull, they shall be located lengthwise on each side of the hull and also on its upper surface on the line of symmetry. Where marks appear on the stabilizer surfaces, they shall appear on the horizontal and on the vertical stabilizers; the marks on the
horizontal stabilizer shall be located on the right half of the upper surface and on the left half of the lower surface, with the tops of the letters towards the leading edge; the marks on the vertical stabilizer shall be Located on each side of the bottom half stabilizers, with the letters placed horizontally.
b) Spherical Balloons (other than unmanned free balloons): The marks shall appear in two places diametrically opposite. They shall be located near the maximum horizontal circumference of the balloon.
c) Non-Spherical Balloons (other than unmanned free balloons): The marks shall appear on each side. They shall be located near the maximum cross section of the balloon immediately above either the rigging band or the points of attachment of the basket suspension cables.
d) Lighter-than-air aircraft: The side marks on lighter-than-air aircraft (other than unmanned free balloons) shall be visible both from the sides and from the ground.
e) Unmanned free Balloons: The marks shall appear on the identification plate.
(ii) Heavier-than-air Aircraft:
a) Wings: The marks shall appear once on the lower surface of the wing structure. They shall be located on the left half of the lower surface of the wing structure unless they extend across the whole of the lower surface of the wing structure. As 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.
b) Fuselage (or Equivalent Structure) and Vertical Tail Surfaces: The marks shall appear either on each side of the fuselage (or equivalent structure) between the wings and tail surface, or on the upper halves of the vertical tail surfaces. When located on a single vertical tail surface they shall appear on both sides. When located on multi vertical tail surfaces they shall appear on the outboard sides of the outer surfaces.
c) Special Cases: If an aircraft does not possess parts corresponding to those mentioned in a) & b),the marks shall appear in a manner such that the aircraft can be identified readily.
Measurements of Nationality and Registration Marks
a) The height of the marks on lighter-than-air aircraft (other than unmanned free
balloons) shall be at least 50 centimeters.
b) The measurements of the marks related to unmanned free balloons shall be
determined taking into account the size of the Payload to which the identification plate is affixed, and shall have prior approval of Director General of Civil Aviation.
c) Special case: If a lighter-than-air aircraft does not possess parts of sufficient
size to accommodate the marks described in , the measurements of
the marks shall have prior approval of the Director General of Civil Aviation.
The height of the marks on the wings shall be at least 50 centimeters.
b) Fuselage (or equivalent structure) and vertical tail surfaces: The height of the marks on the fuselage (or equivalent structure) and on the vertical tail surfaces shall be at least 30 centimeters.
c) Special case: If a heavier-than-air aircraft does not possess parts corresponding to those mentioned in 12.2 a) and 12.2 b) or if the parts are too small to accommodate the marks described therein, the measurements of the marks shall have prior approval of the Director General of Civil Aviation.
Types of Characters for Nationality and Registration Marks:
(a) The letters used for Nationality and Registration marks shall be of equal height.
(b) The letters shall be capital letters in Roman characters without any ornamentation.
(c) The width of each letter (except the letter I) and the length of hyphens shall be two-thirds of the height of a letter.
(d) The letters and hyphens shall be formed by solid lines and shall be of a color contrasting clearly with the background. The thickness of the lines shall be one-sixth of the height of a letter.
(e)Each letter shall be separated from thatwhich it immediately precedes or follows, by a space of not less than one quarter of a letter’s width. A hyphen shall be regarded as a letter for this purpose.
(f) The letters shall always be kept in good condition, so that they are read clearly and easily.
