Regulation OTAR Part 125 - Complex General Aviation

liable to be subject to cosmic radiation in excess of 1 millisievert (mSv) in any period of
12 months;
(2) take into account the assessed exposure when organising work schedules with a view
to reducing the doses of highly exposed crew members;
(3) inform the crew members concerned of the health risks their work involves; and
(4) retain assessments of exposure to cosmic radiation for the periods specified in
91.1265.
Note: The exposure of crew in aircraft that do not generally operate above 26,000 feet is likely to
result in an annual dose less than 1 mSv in any 12 month period.

(b) The operator shall ensure that the working schedules for female crew members, once they have
notified the operator that they are pregnant, keep the equivalent dose to the foetus as low as can
reasonably be achieved and in any case ensure that the dose does not exceed 1 mSv for the
remainder of the pregnancy.
(c) The operator shall ensure that for any flight operated above 49,000 feet:
(1) procedures for operating above 49,000 feet and for the use of monitoring equipment
shall be specified in the operations manual;
(2) a descent to 49,000 feet or lower is initiated as soon as practicable if the limit values of
cosmic radiation dose rate specified in the operations manual are exceeded.
OTAR.125.325 Flight crew communication
The operator shall ensure that all flight crew members required to be on flight deck duty shall communicate
through boom or throat microphones below the transition altitude.
OTAR.125.335 Fuelling operations
(a) Notwithstanding OTAR 91.335, the operator shall ensure that an aircraft is not refuelled or
defuelled when passengers are embarking, on board or disembarking unless:
(1) the aircraft is properly attended by qualified personnel ready to initiate and direct an
evacuation by the most practical and expeditious means available; and
(2) two-way communication is maintained by use of the aeroplane inter-communication
system or other suitable means between the ground crew supervising the refuelling or
defuelling and the qualified personnel on board the aircraft.
OTAR.125.340 Fuel spillage
The operator shall have a system for dealing with fuel spillage.
OTAR.125.370 Aerial work and specialised operations
Note: When complying with 91.370(b), (c) and (d) the operator should utilise his safety management
system, and ensure that the standard operating procedures requirements in 125.170 are satisfied.
OTAR.125.415 IFR departure limitations
The operator shall ensure that:
an IFR flight does not take off when meteorological conditions are below prescribed IFR landing minima
unless meteorological reports and forecasts indicate that a successful approach and landing can be made
at the take-off alternate.
Note: Subpart SPA contains material with regard to: aerodrome considerations; training; operating
procedures; and minimum equipment, which may be used in the construction of operating procedures and
training for Low Visibility Take-off (LVTO).
OTAR.125.420 Minimum flight altitudes
The operator shall specify, in the operations manual, the method for establishing terrain clearance
altitudes.
OTAR.125.435 Instrument approach procedures
The operator shall ensure that procedures for carrying out instrument approaches are specified as
standard operating procedures and included within the operations manual.
OTAR.125.502 Performance planning – aeroplanes
The operator shall ensure that:
(a) when determining the performance of the aeroplane, account is taken of at least the following
factors:
(1) the mass of the aeroplane; and
(2) the pressure altitude and temperature; and
(3) wind - not more than 50 % of the reported head-wind component, or if operations with
a tail-wind are permitted and performance data is provided, not less than 150 % of the
reported tail-wind component;
(4) aeroplane operating techniques
(5) runway gradient;
(6) condition of runway;
(7) water surface state (where relevant).
(b) Due account is taken of aeroplane configuration, environmental conditions and the operation of
