Regulation OTAR Part 125 - Complex General Aviation

at the destination alternate; and
(4) to the extent possible, helideck availability shall be guaranteed at the destination
alternate; and
(5) a landing forecast indicating the likelihood of visual meteorological conditions at the
intended offshore destination and the offshore destination alternate based upon
accredited meteorological information conforming to the standards in ICAO Annex 3,
shall be required for the decision to go beyond PNR; and
(6) an offshore destination alternate shall not be used if fog is forecast or observed within
100 km of the destination; and
(7) offshore alternates shall not be used when it is possible to carry enough fuel to have an
onshore alternate; the use of offshore alternates shall be exceptional and shall not be
used for the purposes of payload enhancement during adverse weather conditions.
OTAR.125.280 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 aircraft-specific dat 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 until landing at the destination aerodrome taking into account the operating
conditions of 125.280(b)(2); and
(3) contingency fuel, which shall be the amount of fuel sufficient to compensate for
unforeseen factors. It shall not be less than 5 % of the planned trip fuel; 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 a flight is operated without a destination alternate aerodrome in
accordance with 91.265(a)(1) or 91.265(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
(iii) when a flight is operated without a destination alternate aerodrome in
accordance with 91.265(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 a piston-engined
aeroplane to fly for 45 minutes, or a helicopter or turbine-engined aeroplane to
fly for 30 minutes, at holding speed at 1,500 ft (450 m) above aerodrome
elevation in standard conditions, calculated with the estimated mass on
arrival at the destination alternate aerodrome or the destination aerodrome,
when no destination alternate aerodrome is required; and
(ii) the operator shall determine one final reserve fuel value for each aeroplane
type and variant in their fleet rounded up to an easily recalled figure; and
