THE HONG KONG GOVERNMENT GAZETTE, NOVEMBER 12, 1937.
42. No fixed balloon, kite, or moored airship shall be elevated in the vicinity of any aerodrome without permission duly given under the law of the country in which the aerodrome is situated. As re- spects aerodromes situated in the Colony such permission may be given by the Governor.
Rules to be observed for Departures and Landings.
43. If a flying machine starting from or about to land on an aerodrome makes a circuit or partial circuit, the turning shall be made clear of the landing area and shall be left-handed (anti-clock- wise) so that during such circuit the landing area shall always be on its left, unless either of the signals provided for in paragraph 15 (4) (b) of this Schedule is displayed, when the turning shall be right- handed.
44.-(1) Every flying machine when taking off from or landing at an aerodrome shall do so upwind, except when the natural conditions of the aerodrome do not permit. If, however, there is a landing T as provided for in sub-paragraph (2) of paragraph 15 of this Schedule or a line of lights or lights in the form of a T as provided for in sub-paragraph (2) (d) (ii) of paragraph 16 of this Schedule, the flying machine shall take off or land in the direction indicated by the T (ie., by following the direction of the shaft of the T towards the cross arm of the T) or by the line of lights or lights in the form of a T as the case may be.
(2) Landings shall be preceded by a descent in a straight line, commencing at least 300 yards outside the perimeter of the landing
area.
(3) Every flying machine landing at an aerodrome shall leave clear on its left any flying machine which has already landed or is already landing, or, which is taking off or about to take off.
(4) Every flying machine taking off from an aerodrome shall leave clear on its left any flying machine which is already taking off.
(5) In observing the rules contained in this paragraph, every flying machine, when landing or taking off, shall leave a reasonable space on its right for other flying machines to land or take off.
(6) At an aerodrome two or more flying machines shall not take off or land simultaneously unless such simultaneous taking off or landing is prearranged.
(7) For the purposes of this paragraph two or more flying machines taking off or landing simultaneously by prearrangement shall be regarded as a single flying machine.
45.-(1) By way of exception the landing area at an aerodrome may be regarded as divided into two approximately equal zones by a vertical plane orientated in the direction of departure and landing described in sub-paragraph (1) of paragraph 44 of this Schedule; in such a case, for an observer facing in the same direction as that in which departures and landings are to be made, the zone on the right shall be reserved for landings, and the zone on the left for departures.
(2) The aerodromes to which this paragraph applies shall be in- dicated by the signal provided for in sub-paragraph (3) of paragraph 15 of this Schedule.
(3) At aerodromes to which this paragraph applies a flying machine when landing shall do so in conformity with the provisions of sub-paragraphs (1) and (2) of paragraph 44 of this Schedule, as far as possible to the left in the zone reserved for that purpose, but leaving clear on its left any other flying machine which has already landed or which is landing.
(4) At aerodromes to which this paragraph applies a flying machine when taking off shall do so in conformity with the provisions of sub-paragraph (1) of paragraph 44 of this Schedule, as far as possible to the left in the zone reserved for that purpose but leaving clear on its left any other flying machine which is already taking off.
46. At land aerodromes having a ground control no flying machine having proceeded on to the landing area with the intention of taking off shall take off until it has received permission to do so by the signal specified in sub-paragraph (1) (b) or sub-paragraph (2) (b) of para- graph 18 of this Schedule.
