CAT.POL.A.400 Take-off Regulation (EU) No 965/2012 (a) The take-off mass shall not exceed the maximum take-off mass specified in the AFM for the pressure altitude and the ambient temperature at the aerodrome of departure. (b) For aeroplanes that have take-off field length data contained in their AFM that do not include engine failure accountability, the distance from the start of the take-off roll required by the aeroplane to reach a height of 50 ft above the surface with all engines operating within the maximum take-off power conditions specified, when multiplied by a factor of either: (1) 1,33 for aeroplanes having two engines; (2) 1,25 for aeroplanes having three engines; or (3) 1,18 for aeroplanes having four engines, shall not exceed the take-off run available (TORA) at the aerodrome at which the take-off is to be made. (c) For aeroplanes that have take-off field length data contained in their AFM which accounts for engine failure, the following requirements shall be met in accordance with the specifications in the AFM: (1) the accelerate-stop distance shall not exceed the ASDA; (2) the take-off distance shall not exceed the take-off distance available (TODA), with a clearway distance not exceeding half of the TORA; (3) the take-off run shall not exceed the TORA; (4) a single value of V1 for the rejected and continued take-off shall be used; and (5) on a wet or contaminated runway the take-off mass shall not exceed that permitted for a take-off on a dry runway under the same conditions. (d) The following shall be taken into account: (1) the pressure altitude at the aerodrome; (2) the ambient temperature at the aerodrome; (3) the runway surface condition and the type of runway surface; (4) the runway slope in the direction of take-off; (5) not more that 50 % of the reported headwind component or not less than 150 % of the reported tailwind component; and (6) the loss, if any, of runway length due to alignment of the aeroplane prior to take-off.
