(1) On a flight, conducted in accordance with VFR, the pilot shall not commence take-off unless current meteorological reports, or a combination of current reports and forecasts, indicate that the meteorological conditions along the route, or that part of the route to be flown under VFR, shall, at the appropriate time, be such as to enable compliance with the provisions prescribed in this Part.
(2) A flight, to be conducted in accordance with IFR—
(a) shall not take-off from the departure aerodrome unless meteorological conditions, at the time of use, are at or above the operator’s established aerodrome operating minima for that operator; and
(b) shall not take off or continue beyond the point of in-flight pointer-planning, unless at the aerodrome of intended landing or at each alternate aerodrome to be selected in accordance with regulation 91.07.7, current meteorological reports, or a combination of current reports and forecasters indicate that the meteorological conditions will be, at the estimated time of use, at or above the operator’s established aerodrome operating minima for that operation.
(3) In the case of commercial air transport operations, to ensure that an adequate margin of safety is observed in determining whether or not an approach and landing can be safely carried out at each alternate aerodrome, the operator shall specify appropriate incremental values, acceptable to the Director, for height of cloud base and visibility, to be added to the operator’s established aerodrome operating minima for the estimated time of use of an aerodrome.
