• (a) Each holder of an air operator certificate shall ensure that the take-off weight does not exceed the maximum take-off weight specified in the aeroplane flight manual.
• (b) When calculating the maximum take-off weight to determine compliance with paragraph (a), each holder of an air operator certificate shall, assuming that the critical engine fails at VEF and using a single V1, ensure that--
  • (1) the required accelerate-stop distance does not exceed the accelerate-stop or accelerate slow distance available; and
  • (2) the take-off distance required does not exceed the take-off distance available; and
  • (3) any clearway forming part of the take-off distance available shall not exceed half the length of the take-off run available; and
  • (4) the take-off run does not exceed the take-off run available, using V1 for the rejected and continued take-off.
• (c) When calculating the maximum take-off weight in accordance with paragraph (b), each holder of an air operator certificate shall take account of--
  • (1) aerodrome elevation; and
  • (2) pressure altitude of the aerodrome when the atmospheric pressure varies by more than 1% from the International Standard Atmosphere; and
  • (3) ambient temperature at the aerodrome; and
  • (4) the type of runway surface and the runway surface condition ; and
  • (5) the runway slope in the direction of take-off; and
  • (6) not more than 50% of the reported headwind component or not less than 150% of the reported tailwind component.
