| (1) | A single-engine aeroplane may be operated over any route or airway in IMC if a cloud base at any point along a route of flight is not lower than that which would permit descent in VMC below a minimum en-route altitude published or established by an operator for such route or airway. |
| (2) | In an event of a failure of a critical engine, a twin-engine aeroplane may be operated over any route or airway in IMC if such aeroplane— |
| (a) | is capable of maintaining a minimum en-route altitude published or established by an operator for such route or airway; or |
| (b) | is able to maintain flight to a suitable landing area and a cloud base at any point along a route of flight is not lower than that which would permit descent in VMC below a minimum en-route altitude published or established by an operator for such route or airway and flight in VMC to a suitable landing area. |
| (3) | In an event of a failure of any two engines, an aeroplane having three or more engines may be operated over any route or airway in IMC if such aeroplane is capable of maintaining a minimum en-route altitude published or established by an operator for such route or airway. |
| (4) | Notwithstanding the provisions of subregulations (1), (2) and (3), an aeroplane may be operated over any route or airway in IMC if such aeroplane is capable of landing at an intended destination or alternate aerodrome in accordance with a related landing performance criteria for such aeroplane. |
| (5) | A PIC shall comply with the relevant provisions of Document SA-CATS 93 when planning destination alternate aerodromes. |
| (6) | A CAO shall operate all flights in accordance with such route, aerodrome or other approvals and conditions pertaining to flight operations as are contained in its CAOC. |
| (7) | A CAO shall specify in its operations manual procedures used to determine minimum altitudes to be flown in order to meet obstacle clearance requirements specified in regulation 91.07.2 and, for operations in uncontrolled airspace, the means for ensuring that a navigational capability is maintained while operating on any route used therein. |
| (8) | Subject to the provisions of subregulation (9), a person may not commence a flight unless such person has ascertained, by every reasonable means available, that aerodrome ground facilities and services, including meteorological and rescue firefighting services are— |
| (a) | available as required for a safe operation of an aircraft and protection of passengers; |
| (b) | adequate for a type of operation being conducted; and |
| (c) | functioning normally for their intended purpose. |
| (9) | A CAO, who is unable to comply with the provisions of subregulation (8), shall establish procedures in its operations manual that will ensure an operation will be safely conducted, and such procedures shall, in an event that rescue firefighting services at an aerodrome that may be used are or may be below that for which an aerodrome is certified, include risk assessment as prescribed in Part 140. |
| (10) | A CAO shall report without delay to a responsible authority any observed operational inadequacy of facilities referred to in subregulation (8). |
| (11) | The information related to the level of rescue and firefighting service protection that is deemed acceptable by a CAO shall be contained in the operations manual. |

| (12) | CAO 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. |
