whose dihedral angle is 110 degrees when measured to the right from dead ahead, and visible at a distance of at least 5 miles.

(ii) On the left side, a red light so constructed and fixed as to show an unbroken light between two vertical planes whose dihedral angle is 110 degrees when measured to the left from dead ahead, and visible at a distance of at least 5

niles.

(ii) The said green and red lights shall be fitted so that the green light shall not be seen from the left side, nor the red light from the right side.

(iv) At the rear, and as far aft as possible, a white light shining rearwards and visible in a dihedral angle of 140 degrees bisected by the vertical plane of symmetry of the aircraft, and visible at a distance of at least 3 miles.

(6) A lying machine when manoeuvring on water under its own power, shall, in addition, carry the following light :—

Forward, a white light visible in a dihedral angle of 220 degrees bisected by the vertical plane of symmetry of the aircraft, and visible at a distance of at least 5 miles.

(c) In the case where, in order to fulfil the above conditions, a single light has to be replaced by several lights, the field of visibility of each of these lights should be so limited that only one can be seen at a time."

For paragraph 3, the following paragraph shall be substituted :--

"3. An airship, when in the air or manoeuvring on land or water under its own power, shall carry the following lights :--

(1) Forward, two white lights in a vertical line one above the other and not less than 6 feet apart, both visible at the same time in a dihedral angle of 220 degrees bisected by the vertical plane of symmetry of the aircraft, and visible at a distance of at least 5 miles.

(ii) On the right side, two green lights placed horizontally in a fore and aft direction not less than 6 feet apart, so con- structed and fixed as to show an unbroken light between two vertical planes whose dihedral angle is 110 degrees when measured to the right from dead ahead, and visible at a distance of at least 5 miles.

(iii) On the left side, two red lights placed horizontally in a fore and aft direction not less than 6 feet apart, so constructed and fixed as to show an unbroken light between two vertical planes whose dihedral angle is 110 degrees when measured to the left from dead ahead, and visible at a distance of at least 5 miles.

(iv) The said green and red lights shall be fitted so that the green lights shall not be seen from the left side, nor the red lights from the right side.

(v) At the rear and as far aft as possible, two white lights in a vertical line one above the other and not less than 6 feet apart, shining rearwards, visible in a dihedral angle of 140 degrees bisected by the vertical plane of symmetry of the aircraft, and visible at a distance of at least 3 miles."

For the words "the lights specified in paragraphs 2 (a) and (e) and 3" there shall be substituted the words "the forward and aft lights specified in paragraph 3."

For paragraph 14 the following paragraph shall be substituted :

14.—(a) An aircraft wishing to land at night without being compelled to do so, on an aerodrome having a ground control, shall before landing
