Captive Balloons und Kites.

A. In the case of a captive balloon or kite-

(i) By night, lights shall be shown in accordance with

the following provisions-

(a) the balloon or kite, when flown at an altitude exceeding 200 feet above the ground, or at any altitude if it is less than 3 statute miles from an aerodromy, shall show a group of two steady lights consisting of an unobstructed white light of at least 5 candles placed 12 feet vertically above an unobstructed red light of at least 5 candles both being visible, so far as is reasonably practic- able, in all directions, and the white light being placed not less than 15 feet or more than 30 feet below the basket; or, if there is no basket, below the lowest part of the balloon or kite;

(b) in addition, from the mooring cable of the balloon or kite there shall be displayed, at in- tervals of 1,000 feet measured from the said group of two lights, similar groups of two lights, white and red, and, if the lowest group of lights is obscured by clouds, an additional group sha!| be displayed below the cloud base;

(e) in addition, the position of the object to which the balloon or kite is moored on the ground shall be marked by a group of three flashing lights arranged in a horizontal plane at the apexes of a triangle approximately equilateral and each side of which measures at least 8o feet; one side of this triangle shall be perpendicular to the horizontal projection of the cable and shall be delimited by two red lights; the third light shall be a green light placed opposite the direction of the cable:

(ii) By day, the mooring cable of a captive balloon shall have attached to it at intervals of not more than 600 feet measured from the basket, or, if there is no basket, from

the lowest part of the balloon, tubular stremmers not less than 16 inches in diameter and 6 feet in length, and marked with alternate bands of white and red 20 inches in width:

(ii) By day, the mooring cable of a kite shall be marked,

either-

(a) in the manner required by the last preceding sub-

paragraph in the case of a captive balloon; or (b) by streamers of stout paper attached to the cable at intervals of 300 feet measured from the lowest part of the kite, such streamers to be not less than 32 inches in length or 1 foot in width in their widest part and marked with alternate bands of white and red 4 inches wide:

(iv) By way of exception to the provisions of this sub- paragraph, captive balloons and kites used for meteoro- logical observations which, owing to their insufficient static lift, cannot display the lights and markings required by this sub-paragraph to he displayed may be flown, sub- ject to the permission in writing of the Director, but only over areas which are notified as danger areas.

In every such case the position of the object to which the captive balloon or kite is moored on the ground shall be marked as required by sub-paragraph (i) (c) of this sub-paragraph.

Moorad Airships.

B. In the case of a moored airship-

(i) when moored to a mooring mast the airship shall show by night at or near the rear an unobstructed white light of at least 5 candles showing, so far as is reasonably practicable, in all directions:

(ii) when moored to the surface of the ground or water by a

cable the airship shall show the following steady lights-

(a) an unobstructed white light of at least 5 candles showing ahead through angles of 110° from dead ahead to each side in its horizontal plane;
