The owner or operator of an aircraft shall select destination or alternate aerodromes in accordance with regulation 91.07.5 when planning a flight. |
| (2) |
The owner or operator shall select a departure, destination or alternate aerodrome only when the serviceability status of the aerodrome permits safe operation of the type of aircraft concerned. |
| (3) |
A take-off alternate aerodrome shall be selected and specified in the operational and ATS flight plan, as regulated in by-Regulation 91.03.4 if the meteorological conditions at the aerodrome of departure are at or below the applicable aerodrome operating minima or it would not be possible to return to the aerodrome of departure for other reasons. |
[Regulation 91.07.7(3) substituted by regulation 13(a) of Notice No. R. 535, GG 36712, dated 30 July 2013 (Fourth Amendment to the Civil Aviation Regulations, 2013)]

| (a) |
twenty (20) minutes flying time from the departure aerodrome in the case of single-engine aeroplanes; |
| (b) |
for aeroplanes with two engines, one hour of flight time at a one-engine inoperative cruising speed, determined form the aircraft flight manual referred to in regulation 91.03.2, calculated in International Standard Atmosphere (ISA) and still-air conditions using the actual take-off mass; or |
| (c) |
for aeroplanes with three or more engines, two hours of flight time at an allengine cruising speed, determined from the aircraft flight manual, calculated in ISA and still-air conditions using the actual take-off mass; |
| (d) |

En-route alternate aerodromes, required by subregulation 91.07.7(4) for extended diversion time operations by aeroplanes with two turbine engines, shall be selected and specified in the air traffic services (ATS) flight plan. |
Provided that if the aircraft flight manual referred to in regulation 91.03.2 does not contain a one-engine inoperative cruising speed as referred to in subregulations (b) and (c), the speed to be used for calculation shall be the speed which is achieved with the remaining engine or engines set at maximum continuous power.
[Regulation 91.07.7(3) substituted by regulation 13(a) of Notice No. R. 535, GG 36712, dated 30 July 2013 (Fourth Amendment to the Civil Aviation Regulations, 2013)]
| (5) |
The owner or operator of a helicopter shall select at least one destination alternate aerodrome for each IFR flight, unless the meteorological conditions prevailing are such that, for the period from one hour before until one hour after the expected time of arrival at the destination aerodrome, the approach from the minimum sector safe altitude and landing can be made in VMC. |
| (6) |
For a flight to be conducted in accordance with instrument flight rules, the owner or operator of an aeroplane shall select at least one destination alternate aerodrome which shall be specified in the ATS flight plan, unless— |
| (a) |
the duration of the flight from the departure aerodrome, or from the point of in-flight re-planning to the destination aerodrome is such that, taking into account all meteorological conditions and operational information relevant to the flight, at the estimated time of use, a reasonable certainty exists that: |
| (i) |
the approach and landing may be made under visual meteorological conditions; and |
| (ii) |
separate runways are usable at the estimated time of use of the destination aerodrome with at least one runway having an operational instrument approach procedure. |
| (b) |
the aerodrome is isolated. Operations into isolated aerodromes do not require the selection of a destination alternate aerodrome(s) and shall be planned in accordance with subregulation 91.07.12(3)(d) and |
| (i) |
for each flight into an isolated aerodrome a point of no return shall be determined; and |
| (ii) |
a flight to be conducted to an isolated aerodrome shall not be continued past the point of no return unless a current assessment of meteorological conditions, traffic and other operational conditions indicate that a safe landing can be made at the estimated time of use. |
Note. - Separate runways are two or more runways at the same aerodrome configured such that if one runway is closed, operations to the other runway(s) can be conducted.
[Regulation 91.07.7(6) substituted by regulation 13(b) of Notice No. R. 535, GG 36712, dated 30 July 2013 (Fourth Amendment to the Civil Aviation Regulations, 2013)]
| (7) |
Except as provided in subregulations (10) and (13), when planning a flight, the owner or operator shall only select an aerodrome as a destination or alternate aerodrome if the appropriate weather reports or forecasts, or a combination thereof, are at or above the applicable planning minima for a period of one hour before to one hour after the estimated time of arrival of the aircraft at the aerodrome. |
| (8) |
The owner or operator of a helicopter shall select at least one destination alternate aerodrome for each IFR flight unless— |
| (a) |
available current meteorological information indicates that the following meteorological conditions will exist from two hours before to two hours after the estimated time of arrival, or from the actual time of departure to two hours after the estimated time of arrival, whichever is the shorter period— |
| (i) |
a cloud base of at least 400ft above the minimum associated with the instrument approach procedure; and |
| (ii) |
visibility of at least 1.5 km more than the minimum associated with the procedure, or |
| (b) |
the heliport of intended landing is isolated and no suitable alternate is available and— |
| (i) |
an instrument approach procedure is prescribed for the isolated heliport of intended landing; and |
| (ii) |
a point of no return (PNR) is determined in case of an offshore destination. |
| (9) |
Suitable offshore alternates for helicopters may be specified subject to the following— |
| (a) |
the offshore alternates shall be used only after passing a PNR. Prior to a PNR, onshore alternates shall be used; |
| (b) |
mechanical reliability of critical control systems and critical components shall be considered and taken into account when determining the suitability of the alternate; |
| (c) |
one-engine inoperative performance capability shall be attainable prior to arrival at the alternate; |
| (d) |
to the extent possible, deck availability shall be guaranteed; and |
| (e) |

| (b) |
Meteorological information is not available. |

Notwithstanding the provision in subregulations 91.07.7(3), 91.07.7(6), and 91.07.7(8), the Director may, based on the results of a specific safety risk assessment conducted by the owner or operator which demonstrate how an equivalent level of safety will be maintained approve operational variations to alternate aerodrome selection criteria. The specific safety risk assessment shall include at least the: |
| (a) |
Capabilities of the pilot-in-command or operator; |
| (b) |
