CAT.OP.MPA.191Fuel/energy scheme – Fuel/energy planning and in-flight re-planning policy – helicopters
(a)As part of the fuel/energy scheme, the operator shall establish a fuel/energy planning and inflight re-planning policy to ensure that the aircraft carries a sufficient amount of usable fuel/energy to safely complete the planned flight and to allow for deviations from the planned operation.
(b)The operator shall ensure that the fuel/energy planning of flights is based upon at least the following elements:
(1)procedures contained in the operations manual as well as:
(i)current aircraft-specific data derived from a fuel/energy consumption monitoring system; or
(ii)data provided by the aircraft manufacturer; and
(2)the operating conditions under which the flight is to be conducted including:
(i)aircraft fuel/energy consumption data;
(ii)anticipated masses;
(iii)anticipated meteorological conditions;
(iv)the effects of deferred maintenance items or of configuration deviations, or both; and
(v)procedures and restrictions introduced by air navigation service providers.
(c)The operator shall ensure that the pre-flight calculation of the usable fuel/energy that is required for a flight includes:
(1)taxi fuel/energy, which shall not be less than the amount expected to be used prior to take-off;
(2)trip fuel/energy;
(4)destination alternate fuel/energy if a destination alternate aerodrome is required;
(5)final reserve fuel/energy, which shall not be less than:
(i)if flying under visual flight rules (VFR) and navigating by day with reference to visual landmarks, 20-minute fuel/energy at best-range speed; or
(ii)if flying under VFR and navigating by means other than by reference to visual landmarks or at night, 30-minute fuel/energy at best-range speed; or
(iii)if flying under instrument flight rules (IFR), 30-minute fuel/energy at holding speed at 1 500 ft (450m) above the aerodrome elevation in standard conditions, calculated according to the helicopter estimated mass on arrival at the destination alternate aerodrome or at the destination aerodrome when no destination alternate aerodrome is required;
(6)extra fuel/energy, to take into account anticipated delays or specific operational constraints; and
(7)discretionary fuel/energy, if required by the commander.
(d)The operator shall ensure that if a flight has to proceed along a route or to a destination aerodrome other than the ones originally planned, in-flight re-planning procedures for calculating the required usable fuel/energy include:
(1)trip fuel/energy for the remainder of the flight;
(2)reserve fuel/energy consisting of:
(i)contingency fuel/energy;
(ii)alternate fuel/energy if a destination alternate aerodrome is required;
(iii)final reserve fuel/energy; and
(iv)additional fuel/energy, if required by the type of operation;
(3)extra fuel/energy, to take into account anticipated delays or specific operational constraints; and
(4)discretionary fuel/energy, if required by the commander.
(e)As an alternative to points (b) to (d), for helicopters with a maximum certified take-off mass (MCTOM) of 3 175 kg or less, flying by day and over routes navigated by reference to visual landmarks, or for local helicopter operations (LHO), the fuel/energy policy shall ensure that on completion of the flight, or series of flights, the final reserve fuel/energy is sufficient for:
(1)30-minute flying time at best-range speed; or
(2)20-minute flying time at best-range speed, if operating within an area providing continuous and suitable operating sites.
