Regulation OTAR Part 135 - CAT - Helicopters and Small Aeroplanes

(b) where necessary, has been given appropriate de/anti-icing treatment; and
(c) details of any de/anti-icing treatment recorded in the aircraft technical log.

OTAR.135.215 Operating in icing conditions - flight procedures
The operator shall establish procedures for flight in expected or actual icing conditions if the aircraft is
certificated and equipped to cope with such conditions.
OTAR.135.225 Use of aerodromes/operating sites
The operator shall:
(a) only authorise use of aerodromes that are adequate for the type(s) of aeroplane and operation(s)
concerned;
(b) as part of his safety management system, assess the level of rescue and fire fighting service
(RFFS) protection available at any aerodrome intended to be specified in the operational flight
plan in order to ensure that an acceptable level of protection is available for the aeroplane to be
used;
(c) ensure that any aerodrome or landing site to be used in its operations is described in Part C of
the operations manual;
(d) ensure that information related to the level of RFFS protection that is deemed acceptable by the
operator shall be contained in the operations manual;
Note 1: ICAO Annex 6 Part I Attachment K contains guidance on assessing an acceptable level
of RFFS protection at aerodromes.
Note 2: It is not intended that this guidance limit or regulate the operation of an aerodrome. The
assessment performed by the operator does not in any way affect the RFFS requirements of
ICAO Annex 14, Volume I, for aerodromes;
(e) for a helicopter flying at night, ensure that adequate lighting is in operation at any operating site
where it is intended to take off or land.
OTAR.135.240 Aerodrome operating minima – determination
(a) The operator shall establish aerodrome operating minima for each aerodrome to be used in
operations in accordance with:
(1) SubPart B, Operational Procedures, to Annex IV, Part CAT (and associated
AMCs/GMs) of European Commission Regulation (EU) 800/2013 'Air Operations'.
(b) For each alternate aerodrome, the operator shall specify appropriate incremental values for
height of cloud base and visibility to be added to the applicable aerodrome operating minima, in
order to ensure that an adequate margin of safety is observed in determining whether or not an
approach and landing can be safely carried out.
(c) The method of determining aerodrome operating minima shall be approved by the Governor and
included in the operations manual.
Note: Guidance on the selection of the incremental values in (b) is contained in the Flight
Planning and Fuel Management Manual (ICAO Doc 9976).
OTAR.135.245 Noise abatement procedures
(a) The operator’s noise abatement procedures for departure and arrival/approach for each
aeroplane type, shall be designed to be simple and safe to operate with no significant increase in
crew workload during critical phases of flight.
(b) The pilot-in-command shall follow noise abatement procedures unless these would have a
detrimental effect on aircraft safety.
OTAR.135.255 Take-off alternate
(a) The operator shall ensure that a take-off alternate aerodrome is selected and specified in the
operational flight plan if either: the meteorological conditions at the aerodrome of departure are at
or below the applicable aerodrome operating minima for landing; or, it would not be possible to
return to the aerodrome of departure for other reasons.
(b) The take-off alternate aerodrome shall be located within the following flight time from the
aerodrome of departure:
(1) for an aeroplane with two engines, one hour of flight time at a one-engine-inoperative
cruising speed determined from the aircraft operating manual, calculated in ISA and
still-air conditions using the actual take-off mass;
(2) for an aeroplane with three or more engines, two hours of flight time at an all-engine
operating cruising speed, determined from the aircraft operating manual, calculated in
ISA and still-air conditions using the actual take-off mass;
(3) for aeroplanes engaged in extended diversion time operations (EDTO) where an
alternate aerodrome meeting the distance criteria of (b)(1) or (b)(2) is not available, the
first available alternate aerodrome located within the distance of the operator’s
approved maximum diversion time considering the actual take-off mass.
OTAR.135.260 En-route alternate
En-route alternate aerodromes, required for extended diversion time operations by aeroplanes with two
turbine engines, shall be selected and specified in both the operational and ATS flight plans.
