Canadian Aviation Regulations

Version of section 704.49 from 2019-06-28 to 2023-01-25:

  •  (1) Subject to subsection (3), no person shall dispatch or conduct a take-off in an aeroplane unless

    • (a) in the case of a turbo-jet-powered aeroplane, the weight of the aeroplane on landing at the destination aerodrome and at the alternate aerodrome will allow a full-stop landing within 60% of the landing distance available (LDA);

    • (b) in the case of a large aeroplane that is propeller-driven, the weight of the aeroplane on landing at the destination aerodrome and at the alternate aerodrome will allow a full-stop landing within 70% of the landing distance available (LDA); or

    • (c) in the case of a large aeroplane that is propeller-driven and equipped with reverse thrust, the weight of the aeroplane on landing at the destination aerodrome and at the alternate aerodrome will allow a full-stop landing within 80% of the landing distance available (LDA) if

      • (i) the approach speed does not exceed an indicated airspeed of 100 knots, taking into account the estimated weight of the aeroplane, the flap setting and the ambient conditions expected on arrival,

      • (ii) the reverse thrust is operative and the runway surface conditions permit the use of full-rated reverse thrust,

      • (iii) the aeroplane is operated on a paved, hard-surface runway,

      • (iv) the runway surface is forecast to be bare and dry at the estimated time of arrival,

      • (v) each flight crew member has completed specific training on short-field landing techniques on that type of aeroplane within the 12 months preceding the flight, and

      • (vi) the glide-path angle specified in the Canada Air Pilot or the Restricted Canada Air Pilot is not greater than 3 degrees and the runway threshold crossing height is not greater than 15 m (50 feet).

  • (2) In determining whether an aeroplane may be dispatched or a take-off may be conducted under subsection (1), the following shall be taken into account:

    • (a) the pressure-altitude at the destination aerodrome and at the alternate aerodrome;

    • (b) a wind component that is not more than 50% of the reported headwind or not less than 150% of the reported tailwind at the destination aerodrome and at the alternate aerodrome; and

    • (c) the suitability of the runway with respect to the wind speed and direction, the ground handling characteristics of the aeroplane, the landing aids and the terrain.

  • (3) If conditions at the destination aerodrome at the time of take-off do not permit compliance with the requirement set out in paragraph (2)(c), an aeroplane may be dispatched and a take-off may be conducted if conditions at the alternate aerodrome designated in the operational flight plan permit, at the time of take-off, compliance with the requirements set out in paragraph (1)(a) or (b) and subsection (2).
