| (1) | Aeroplane dispatched over any route or airway in IMC shall be capable of— |
| (a) | in the case of a twin engine aeroplane in the event of the failure of the critical engine, maintaining the minimum en route altitude published or established by the operator for such route or airway; |
| (b) | in the case of an aeroplane having three or more engines in the event of the failure of any two engines, maintaining the minimum en route altitude published or established by the operator for such route or airway; and |
| (c) | in addition to subparagraphs (a) and (b) and for flight in VMC, the aeroplane shall be capable of landing at the intended destination or alternate aerodrome in accordance with the provisions of regulations 121.08.8, 121.08.9 and 121.08.10. |
| (2) | The operator shall specify in its operations manual the procedures used to determine the minimum altitudes to be flown in order to meet the obstacle clearance requirements specified in regulation 121.07.27 and, for operations in uncontrolled airspace, the means for ensuring a navigational capability is maintained while operating on any route used therein. |
| (3) | The operator of an aeroplane shall select at least one destination alternate aerodrome for each IFR flight unless— |
| (a) | two separate runways, arranged such that the closure of one cannot affect the operations of the other and each with an operational straight-in instrument approach procedure, are available and usable by the flight crew at the destination aerodrome; and |
| (b) | the duration of the flight from the departure aerodrome, or from the point of in-flight replanning, to the destination aerodrome is such that, taking into account all operational information relevant to the flight, for a period of at least one hour before and one hour after the estimated time of arrival, a reasonable certainty exists that the approach and landing may be made under VMC; or |
| (c) | the destination aerodrome is isolated and no suitable alternate aerodrome is available, in which case the provisions of regulation 91.07. 7(6)(b) shall apply. |
| (4) | The operator of an aeroplane shall select at least two destination alternate aerodromes for IFR flights when the appropriate weather reports or forecasts for the destination aerodrome, or any combination thereof, indicate that during a period commencing one hour before and ending one hour after the estimated time of arrival, the weather conditions will be below the applicable planning minima or no weather information is available at the destination aerodrome. |
| (5) | An air service operator shall not permit, nor may a PIC operate, a flight that is to be conducted in accordance with IFR, for which one or more destination alternate aerodromes are required, to be commenced unless the aerodrome meteorological forecast indicates that conditions for a period of at least one hour before until one hour after the estimated time of arrival at the destination alternate aerodrome(s) will meet or exceed those specified in Document SA-CATS 121. |
| (6) | The operator shall operate all flights in accordance with such route, aerodrome or other approvals and conditions pertaining to flight operations as are contained in the AOC. |
| (7) | The operator shall ensure that— |
| (a) | the equipment of the aeroplane intended to be used, complies with the minimum requirements for the planned operation; and |
| (b) | except as approved by the Director in accordance with Document SA-CATS 121, no twin-engine aeroplane is operated under this Part over a route which contains a point further from an adequate and suitable aerodrome than the distance that can be flown, under standard conditions in still air, in 60 minutes at the one-engine inoperative cruise speed. |
| (8) | An operator of an aeroplane shall not commence a flight unless it has been ascertained by every reasonable means available that the ground facilities and services, including meteorological services and rescue firefighting services are— |
| (a) | available as required for the safe operation of an aeroplane and the protection of the passengers. |
| (b) | adequate for the type of operation being conducted; and |
| (c) | functioning normally for their intended purpose. |

| (9) | The operator shall report without delay to the responsible authority any observed operational inadequacy of facilities referred to in subregulation (8). |
| (10) | Information related to the level of rescue and firefighting service protection that is deemed acceptable by an operator of an aeroplane shall be contained in the operations manual. |

| (11) | An operator of an aeroplane shall, as part of its SMS, assess the level of rescue and firefighting service protection available at an aerodrome intended to be specified in the operational flight plan to ensure that an acceptable level of protection is available for an aeroplane intended to be used. |
