1. “Glider” means a non-power-driven heavier-than-air aircraft, deriving its lift in flight chiefly from aerodynamic reactions on surfaces which remain fixed under given conditions of flight;
1. “Heavier-than-air aircraft” means any aircraft deriving its lift in flight chiefly from aerodynamic forces;
1. “Lighter-than-air aircraft” means any aircraft supported chiefly by its buoyancy in the air;
1. “State of Registry” means the State on whose register the aircraft is entered.

4.1.1.3 Acronyms

1. (b) have no ornamentation;

1. (d) be legible; and
1. (e) have a hyphen placed between the nationality mark and the registration mark.

4.3.1.3 Display of Marks: General

(1) The nationality mark of the aircraft shall consist of the Roman capital letter denoting the nationality of Saint Lucia followed by the registration number of the aircraft in Arabic numerals. Each suffix letter used in the marks displayed must also be a Roman capital letter.

(2) If, because of the aircraft configuration, it is not possible to mark the aircraft in accordance with this Part, the owner may apply to the Authority for a different procedure.

4.3.1.4 Size of Marks

(2) Height. The character marks in each separate group shall be of equal height and on—
1. (a) Fixed-wing aircraft:
  1. (i) Wings- shall be at least 50 centimeters,
  1. (ii) Fuselage and vertical tail surfaces:- shall be at least 30 centimeters high;
1. (b) rotorcraft shall be at least 30 centimeters high; and
1. (c) lighter-than-air aircraft at least 50 centimeters high.

(3) Width. Characters must be two-thirds as wide as they are high, except the number “1”, which must be one-sixth as wide as it is high, and the letters “M” and “W” which may be as wide as they are high.

(4) Thickness. Characters shall be formed by solid lines one-sixth as thick as the character is high.

(5) Spacing. The space between each character may not be less than one-fourth of the character width.

(6) Uniformity. The marks required by this Part for fixed-wing aircraft must have the same height, width, thickness, and spacing on both sides of the aircraft.

(7) The operator of an aircraft penetrating an ADIZ or DEWIZ shall display on that aircraft temporary or permanent nationality and registration marks at least 30 centimeters high.

4.3.1.5 Deviations for Size and Location of Marks

(1) If either one of the surfaces authorized for displaying required marks is large enough for display of marks meeting the size requirements of this section and the other is not, the operator shall place full-size marks on the larger surface.

(2) If neither surface is large enough for full-size marks, the Authority may approve marks as large as practicable for display on the larger of the 2 surfaces.

4.3.1.6 Location of Marks on Fixed-wing Aircraft

(1) The operator of a fixed-wing aircraft shall display the required marks 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 both wings and, either the vertical tail surfaces or the sides of the fuselage.

(2) The marks required by paragraph (1) shall be displayed as follows:
1. (a) if displayed on the vertical tail surfaces, horizontally on the upper half of both surfaces of a single vertical tail or horizontally on the upper halves of the outer surfaces of a multi-vertical tail;
1. (b) if displayed on the fuselage surfaces, horizontally on both sides of the fuselage between the trailing edge of the wing and the leading edge of the horizontal stabilizer;
1. (c) if engine pods or other appurtenances are located in the area described in paragraph (b) and are an integral part of the aircraft, the operator may place the marks on those pods or appurtenances.

(3) On aircraft having no fixed wing surface 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.

4.3.1.7 Location of Marks on Rotorcraft

The operator of a rotorcraft shall display marks horizontally on both surfaces of the cabin, fuselage, boom, or tail, such that the rotorcraft can be readily identified.

4.3.1.8 Location of Marks on Lighter-Than-Air Aircraft

1. (b) the horizontal and vertical stabilizers surfaces—
  1. (i) for the horizontal stabilizer, located on the right half of the upper surface and on the left half of the lower surface, with the tops of the letters and numbers toward the leading edge, and
  1. (ii) for the vertical stabilizer, located on each side of the bottom half stabilizer, with the letters and numbers placed horizontally.

(2) Spherical balloons (other than unmanned free balloons). The operator shall apply marks to appear in two places diametrically opposite each other and located near the maximum horizontal circumference of the balloon.

(3) Non-spherical balloons (other than unmanned free balloons). The operator shall apply marks to appear on each side, 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.

(4) Lighter-than-air aircraft (other than unmanned free balloons). The operator shall apply side marks to be visible both from the sides and from the ground.

(5) Unmanned free balloons. The operator shall apply marks to appear on the identification plate.

4.3.1.9 Sale of Aircraft: Removal of Marks

When an aircraft that is registered in Saint Lucia is sold, the holder of the certificate of registration shall remove, before its delivery to the purchaser, all nationality and registration marks of Saint Lucia, unless the purchaser is a citizen or other legal entity as prescribed in Regulation 24(2) of Chapter 4.
