Canadian Aviation Regulations

704.47 (1) No person shall conduct a take-off in a large aeroplane if the weight of the aeroplane is greater than the weight specified in the aircraft flight manual as allowing a net take-off flight path that clears all obstacles by at least 35 feet vertically or at least 200 feet horizontally within the aerodrome boundaries, and by at least 300 feet horizontally outside those boundaries, unless

• (a) the take-off is authorized in an air operator certificate; and

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

(2) In the determination of the maximum weight, minimum distances and flight path referred to in subsection (1),

• (a) corrections shall be made for

  • (i) the runway to be used,

  • (ii) the runway slope in the direction of take-off,

  • (iii) the pressure-altitude at the aerodrome,

  • (iv) the ambient temperature, and

  • (v) the wind component at the time of take-off, where not more than 50 per cent of the reported headwind component or not less than 150 per cent of the reported tailwind component is considered; and

• (b) calculations shall be based on the pilot

  • (i) not banking the aeroplane before reaching an altitude of 50 feet,

  • (ii) subject to subsection (3), using 15 degrees or less of bank at or below 400 feet, and

  • (iii) using no more than 25 degrees of bank thereafter, aircraft speed and configuration permitting.

(3) A bank angle greater than the 15 degrees referred to in subparagraph (2)(b)(ii) may be used if it is authorized in an air operator certificate.
