NCO.OP.125 Fuel and oil supply — aeroplanes
(a) The pilot-in-command shall only commence a flight if the aeroplane carries sufficient fuel and oil for the following:
(1) for visual flight rules (VFR) flights:
(i) by day, taking-off and landing at the same aerodrome/landing site and always remaining in sight of that aerodrome/landing site, to fly the intended route and thereafter for at least 10 minutes at normal cruising altitude;
(ii) by day, to fly to the aerodrome of intended landing and thereafter to fly for at least 30 minutes at normal cruising altitude; or
(iii) by night, to fly to the aerodrome of intended landing and thereafter to fly for at least 45 minutes at normal cruising altitude;
(2) for IFR flights:
(i) when no destination alternate is required, to fly to the aerodrome of intended landing and thereafter to fly for at least 45 minutes at normal cruising altitude; or
(ii) when a destination alternate is required, to fly to the aerodrome of intended landing, to an alternate aerodrome and thereafter to fly for at least 45 minutes at normal cruising altitude.
(b) In computing the fuel required including to provide for contingency, the following shall be taken into consideration:
(1) forecast meteorological conditions;
(2) anticipated ATC routings and traffic delays;
(3) procedures for loss of pressurisation or failure of one engine while en-route, where applicable; and
(4) any other condition that may delay the landing of the aeroplane or increase fuel and/or oil consumption.
(c) Nothing shall preclude amendment of a flight plan in-flight, in order to re-plan the flight to another destination, provided that all requirements can be complied with from the point where the flight is re-planned.
