10. Flight preparation.
(1)A flight shall not be commenced until the pilot-incommand is satisfied that—(a)the aeroplane is airworthy, duly registered and that appropriate certificates with respect thereto are aboard the aeroplane;(b)the instruments and equipment installed in the aeroplane are appropriate, taking into account the expected flight conditions;(c)any necessary maintenance has been performed in accordance with Regulations 39, 40, and 41;(d)the mass of the aeroplane and centre of gravity location are such that the flight can be conducted safely, taking into account the flight conditions expected;(e)any load carried is properly distributed and safely secured; and(f)the aeroplane operating limitations, contained in the flight manual, or its equivalent, will not be exceeded.(2)The pilot-in-command should have sufficient information on climb performance with all engines operating to enable determination of the climb gradient that can be achieved during the departure phase for the existing take-off conditions and intended take-off technique.(3)Before commencing a flight the pilot-in -command shall be familiar with all available meteorological information appropriate to the intended flight. Preparation for a flight away from the vicinity of the place of departure, and for every flight under the instrument flight rules, shall include—(a)a study of available current weather reports and forecasts; and(b)the planning of an alternative course of action to provide for the eventuality that the flight cannot be completed as planned, because of weather conditions.(4)VFR flights shall not be commenced unless current meteorological reports or a combination of current reports and forecasts indicate that the meteorological conditions along the route or that part of the route to be flown under VFR will, at the appropriate time, be such as to enable compliance with these rules.(5)A flight to be conducted in accordance with the instrument flight rules shall not—(a)take off from the departure aerodrome unless the meteorological conditions, at the time of use, are at or above the aerodrome operating minima for that operation; and(b)take off or continue beyond the point of in-flight re-planning unless at the aerodrome of intended landing or at each alternate aerodrome to be selected in compliance with subregulation (6), current meteorological reports or a combination of current reports and forecasts indicate that the meteorological conditions will be, at the estimated time of use, at or above the aerodrome operating minima for that operation.(6)The Authority shall establish criteria to be used for the estimated time of use of an aerodrome including a margin of time.(7)A flight to be operated in known or expected icing conditions shall not be commenced unless the aeroplane is certificated and equipped to cope with such conditions.(8)A flight to be planned or expected to operate in suspected or known ground icing conditions shall not take off unless the aeroplane has been inspected for icing and, if necessary, has been given appropriate de-icing or anti-icing treatment. Accumulation of ice or other naturally occurring contaminants shall be removed so that the aeroplane is kept in an airworthy condition prior to take-off.(9)A flight shall not be commenced unless, taking into account both the meteorological conditions and any delays that are expected in flight, the aeroplane carries sufficient fuel and oil to ensure that it can safely complete the flight. The amount of fuel to be carried must permit-(a)when the flight is conducted in accordance with the instrument flight rules and a destination alternate aerodrome is not required in accordance with subregulation (5) or when the flight is to an isolated aerodrome, flight to the aerodrome of intended landing, and after that, have a final reserve fuel for at least 45 minutes at normal cruising altitude; or(b)when the flight is conducted in accordance with the instrument flight rules and a destination alternate aerodrome is required, flight to the aerodrome of intended landing, then to an alternate aerodrome, and after that, have a final reserve fuel for at least 45 minutes at normal cruising altitude; or(c)when the flight is conducted in accordance with day VFR, flight to the aerodrome of intended landing, and after that, have a final reserve fuel for at least 30 minutes at normal cruising altitude; or(d)when the flight is conducted in accordance with night VFR, flight to the aerodrome of intended landing and thereafter have a final reserve fuel for at least 45 minutes at normal cruising altitude.(10)The use of fuel after flight commencement for purposes other than originally intended during pre-flight planning shall require a re-analysis and, if applicable, adjustment of the planned operation.(11)An aeroplane shall not be re-fuelled when passengers are embarking, on board or disembarking unless it is attended by the pilotin-command or other qualified personnel ready to initiate and direct an evacuation of the aeroplane by the most practical and expeditious means available.(12)When re-fuelling with passengers embarking, on board or disembarking, two-way communications should be maintained by the aeroplane’s intercommunication system or other suitable means between the ground crew supervising the re-fuelling and the pilot-in-command or other qualified personnel required by subregulation (9).(13)The pilot-in-command shall ensure that breathing oxygen is available to crew members and passengers in sufficient quantities for all flights at such altitudes where a lack of oxygen might result in impairment of the faculties of crew members or harmfully affect passengers.| Absolute pressure | Metres | Feet |
