Enroute Limitations with One Engine Inoperative
704.48 No person shall operate a multi-engined aircraft with passengers on board if the weight of the aircraft is greater than the weight that will allow the aircraft to maintain, with any engine inoperative, the following altitudes:
(a) when operating in IMC or in IFR flight on airways or air routes, the MOCA of the route to be flown;
(b) when operating in IMC or in night VFR flight on routes established by an air operator, the MOCA of the route to be flown; and
(c) when operating in VFR flight, at least 500 feet above the surface.
Dispatch Limitations: Landing at Destination and Alternate Aerodromes
704.49 (1) Subject to subsection (3), no person shall dispatch or conduct a take-off in a turbo-jet-powered aeroplane or in a large aeroplane unless
(a) the weight of the aeroplane on landing at the destination aerodrome will allow a full-stop landing
(i) in the case of a turbo-jet-powered aeroplane, within 60 per cent of the landing distance available (LDA), or
(ii) in the case of a propeller-driven aeroplane, within 70 per cent of the landing distance available (LDA); and
(b) the weight of the aeroplane on landing at the alternate aerodrome will allow a full-stop landing
(ii) in the case of a propeller-driven aeroplane, within 70 per cent of the landing distance available (LDA).
(2) In determining whether an aeroplane can be dispatched or a take-off can be conducted in accordance with subsection (1), the following shall be taken into account:
(a) the pressure-altitude at the destination aerodrome and at the alternate aerodrome;
(b) not more than 50 per cent of the reported headwind component or not less than 150 per cent of the reported tailwind component; and
(c) that the aeroplane must be landed on a suitable runway, considering the wind speed and direction, the ground handling characteristics of the aeroplane, and other conditions such as landing aids and terrain.
(3) Where conditions at the destination aerodrome at the time of take-off do not permit compliance with paragraph (2)(c), an aeroplane may be dispatched and a take-off conducted if the alternate aerodrome designated in the operational flight plan permits, at the time of take-off, compliance with paragraph (1)(b) and subsection (2).
Dispatch Limitations: Wet Runway — Turbo-jet-powered Aeroplanes
704.50 (1) Subject to subsection (2), when weather reports or forecasts indicate that the runway may be wet at the estimated time of arrival, no person shall dispatch or conduct a take-off in a turbo-jet-powered aeroplane unless the landing distance available (LDA) at the destination airport is at least 115 per cent of the landing distance required pursuant to paragraph 704.49(1)(a).
(2) The landing distance available on a wet runway may be shorter than that required by subsection (1), but not shorter than that required by section 704.49, if the aircraft flight manual includes specific information about landing distances on wet runways.
