—(1) A public transport aircraft registered in a country other than Singapore shall not fly in or over Singapore unless the operator thereof shall have furnished to the Minister such particulars as he may from time to time require relating to the aerodrome operating minima specified by the operator in relation to aerodromes in Singapore for the purpose of limiting their use by the aircraft for take-off or landing, including any instruction given by the operator in relation to such weather conditions. The aircraft shall not fly in or over Singapore unless the operator shall have made such amendments of or additions to the aerodrome operating minima so specified and shall comply with any instruction given by the Minister for the purpose of ensuring the safety of the aircraft or the safety, efficiency or regularity of air navigation.
(2) A public transport aircraft registered in a country other than Singapore shall not begin or end a flight at an aerodrome in Singapore in aerodrome operating minima less favourable than those so specified in the Ninth Schedule in relation to that aerodrome, or in contravention of the instructions referred to in sub-paragraph (1).
(3) Without prejudice to sub-paragraph (2), a public transport aircraft registered in a country other than Singapore shall not commence or continue an approach to landing at an aerodrome in Singapore if the runway visual range at that aerodrome is at that time less than the relevant minimum for landing established in accordance with sub-paragraph (1).
(4) For the purposes of this paragraph, “runway visual range”, in relation to a runway or landing strip, means the range over which the pilot of an aircraft on the centreline of a runway can see runway surface markings or the lights delineating the runway or identifying its centreline or, in the case of an aerodrome in Singapore, the distance, if any, communicated to the commander of the aircraft by or on behalf of the person in charge of the aerodrome as being the runway visual range.
