Canadian Aviation Regulations

704.46 (1) No person shall conduct a take-off in an aircraft if the weight of the aircraft

• (a) exceeds the maximum take-off weight specified in the aircraft flight manual for the pressure-altitude and the ambient temperature at the aerodrome where the take-off is to be made; or

• (b) after allowing for planned fuel consumption during the flight to the destination aerodrome or alternate aerodrome, exceeds the landing weight specified in the aircraft flight manual for the pressure-altitude and the ambient temperature at the destination aerodrome or alternate aerodrome.

(2) In the determination of the maximum take-off weight referred to in subsection (1) for a small aeroplane,

• (a) subject to subsection (5), the required accelerate-stop distance shall not exceed the accelerate-stop distance available (ASDA); and

• (b) the all-engines-operating take-off distance shall not exceed the take-off distance available (TODA).

(3) Subject to subsection (5), in the determination of the maximum take-off weight referred to in subsection (1) for a large aeroplane,

• (a) the required accelerate-stop distance shall not exceed the accelerate-stop distance available (ASDA);

• (b) the required take-off run shall not exceed the take-off run available (TORA); and

• (c) the required take-off distance shall not exceed the take-off distance available (TODA).

(4) For the purposes of subsections (2) and (3), the following factors shall be taken into account:

• (a) the pressure-altitude at the aerodrome;

• (b) the ambient temperature;

• (c) the runway slope in the direction of take-off; and

• (d) not more than 50 per cent of the reported headwind component or not less than 150 per cent of the reported tailwind component.

(5) A person may conduct a take-off without meeting the requirements of paragraph (2)(a) or subsection (3) if the person

• (a) is authorized to do so in an air operator certificate; and

• (b) complies with the Commercial Air Service Standards.
