Regulation OTAR Part 135 - CAT - Helicopters and Small Aeroplanes

(2) procedures for EDTO are specified in the operations manual;
(3) the aeroplane is dispatched in accordance with those procedures specified in the
operations manual; and
(4) flight crew are appropriately trained.
(b) A flight shall not proceed beyond the threshold time specified in the EDTO approval unless the
identified en-route alternate aerodromes have been re-evaluated for availability and the most up-
to-date information indicates that, during the estimated time of use, conditions at those
aerodromes will be at or above the applicable aerodrome operating minima for the operation.
(c) If any conditions are identified that would preclude a safe approach and landing at that aerodrome
during the estimated time of use, an alternative course of action shall be determined.
OTAR.135.280 Fuel requirements
Notwithstanding 91.280:
(a) The operator shall establish a fuel and oil policy for the purpose of flight planning, and en-route
re-planning, to ensure that each aircraft carries sufficient fuel and oil for the planned flight,
including reserve fuel to cover deviations from the planned flight.
(b) The fuel and oil policy shall ensure that the planning requirements are based upon:
(1) current aircraft-specific data derived from a fuel consumption monitoring system, if
available; or if current aicraft-specific data is not available, data provided by the aircraft
manufacturer; and
(2) the operating conditions under which the planned flight is to be conducted, including but
not limited to:
(i) anticipated aircraft mass; and
(ii) Notices to Airmen; and
(iii) current meteorological reports or a combination of current reports and
forecasts; and
(iv) air traffic services procedures, restrictions and anticipated delays; and
(v) the effects of deferred maintenance items and/or configuration deviations.

(c) The pre-flight calculation of usable fuel required shall include:
(1) taxi fuel, which shall be the amount of fuel expected to be consumed before take-off,
taking into account local conditions at the departure aerodrome and auxilliary power
unit (APU) fuel consumption; and
(2) trip fuel, which shall be the amount of fuel required to enable the aircraft to fly from
take-off or the point of in-flight re-planning until landing at the destination aerodrome
taking into account the operating conditions of 135.280(b)(2); and
(3) contingency fuel, which shall be the amount of fuel sufficient to compensate for
unforeseen factors. It shall be 5 % of the planned trip fuel or 5 % of the fuel required
from the point of in-flight re-planning based on the consumption rate used to plan the
trip fuel but in any case not less than the amount required to fly for five minutes at
holding speed at 1,500 ft (450m) above the destination aerodrome in standard
conditions; and
Note: Unforeseen factors are those which could have an influence on the fuel
consumption to the destination aerodrome, such as deviations of an individual aircraft
from the expected fuel consumption data, deviations from forecast meteorological
conditions, extended taxi times before take-off, and deviations from planned routings
and/or cruising levels.
(4) destination alternate fuel; which shall be,
(i) if a destination alternate aerodrome is required, the amount of fuel required to
enable the aircraft to perform a missed approach at the destination
aerodrome, climb to the expected cruising altitude, fly the expected routing,
descend to the point where the expected approach is initiated, and conduct
the approach and landing at the destination alternate aerodrome; or
(ii) where two destination alternate aerodromes are required, the amount of fuel,
as calculated in 135.280(c)(4)(i), required to enable the aircraft to proceed to
the destination alternate aerodrome which requires the greater amount of
alternate fuel; or
(iii) when a flight is operated without a destination alternate aerodrome in
accordance with 135.265(a)(2), an amount of fuel sufficient to enable an
aircraft to hold for 15 minutes at 1,500 ft (450 m) above destination
aerodrome elevation in standard conditions; or
(iv) when a flight is operated without a destination alternate aerodrome in
accordance with 135.265(a)(3), an amount of fuel sufficient to enable a
turbine engined aeroplane to hold for 120 minutes; or a piston-engined
aeroplane to fly for 45 minutes plus 15 % of the flight time planned to be
spent at cruising level, including final reserve fuel, or two hours, whichever is
less; and
(5) final reserve fuel,
(i) which shall be the amount of fuel required to enable a helicopter or turbine-
engined aeroplane to fly for 30 minutes, or a piston-engined aeroplane to fly
