Regulation OTAR Part 135 - CAT - Helicopters and Small Aeroplanes

for 45 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
(6) additional fuel, which shall be a supplementary amount of fuel required if the minimum
fuel calculated in accordance with 135.280(c)(2)(3)(4) and (5) is not sufficient to:
(i) allow the aircraft to descend as necessary and proceed to an adequate
alternate aerodrome in the event of engine failure or loss of pressurization,
whichever requires the greater amount of fuel based on the assumption that
such a failure occurs at the most critical point along the route; and
(aa) hold for 15 minutes at 1,500 ft (450m) above aerodrome elevation
in standard conditions; and
(bb) make an approach and landing; and
(ii) allow an aeroplane engaged in extended diversion time operations (EDTO) to
comply with the EDTO critical fuel scenario as established by the Governor;
(iii) meet additional requirements not covered above; and
(7) discretionary fuel, which shall be an amount of fuel to be carried at the discretion of the
pilot-in-command.
(d) .
(1) Variations to the pre-flight calculation of taxi fuel, trip fuel, contingency fuel, destination
alternate fuel and additional fuel specified in (c) shall be subject to the approval of the
Governor, on the basis of a risk assessment provided by the operator.
(2) The risk assessment shall demonstrate how an equivalent level of safety will be
maintained.
(3) The risk assessment shall include:
(i) flight fuel calculations; and
(ii) capabilities of the operator to include a data-driven method that includes a
fuel consumption monitoring programme and/or the advanced use of
alternate aerodromes; and
(iii) specific mitigation measures.
(e) A flight shall not be commenced nor continued beyond the point of in-flight re-planning unless the
usable fuel on board meets the applicable requirements in 135.280(c) or (d).
(f) 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.

Note: Guidance on flight planning including the circumstances that may require re-analysis,
adjustment and/or re-planning of the planned operation before take-off or en-route, is contained in
the Flight Planning and fuel Management Manaual (Doc 9976)
OTAR.135.285 Checklists
(a) The operator shall ensure that flight crews are provided with checklists of normal, abnormal and
emergency aircraft procedures.
(b) The checklists provided to flight crews shall be designed in accordance with human factors
principles and shall contain sufficient information to enable flight crews to comply with the
operating procedures in the operations manual, the aircraft flight manual or such other
documents as may be associated with the certificate of airworthiness.
(c) The operator shall ensure that flight crew operating procedures incorporate the use of checklists
for all phases of aircraft operations and in emergency.
(d) The operator shall ensure that checklists are used by flight crews prior to, during and after all
phases of aircraft operation.
OTAR.135.290 In-flight simulation of emergency situations
The operator shall ensure that on a flight when passengers are being carried, no emergency or abnormal
situations are simulated
OTAR.135.305 In-flight fuel management
(a) The operator shall establish a procedure to ensure that in-flight fuel checks and fuel
management are carried out.
(b) The pilot in command shall ensure that fuel checks are carried out at regular intervals to confirm
that the amount of usable fuel remaining in flight is not less than the fuel required to proceed to
an aerodrome/landing site where a safe landing can be made, with the planned final reserve fuel
remaining.
Note 1: The protection of final reserve fuel is intended to ensure a safe landing at any aerodrome
when unforeseen occurrences may not permit safe completion of an operation as originally
planned. Guidance on flight planning including the circumstances that may require re-analysis,
adjustment and/or re-planning of the planned operation before take-off or en-route, is contained in
the Flight Planning and Fuel Management Manual (Doc 9976)
(c) The pilot-in-command shall request delay information from ATC when unanticipated
