AMC2 CAT.POL.A.400 Take-off
CAA ORS9 Decision No. 1
RUNWAY SLOPE
Unless otherwise specified in the AFM, or other performance or operating manuals from the manufacturers, the take-off distance should be increased by 5 % for each 1 % of upslope. However, correction factors for runways with slopes in excess of 2 % should only be applied when:
(a) the operator has demonstrated to the CAA that the necessary data in the AFM or the operations manual contain the appropriated procedures; and
(b) the crew is trained to take-off on runways with slopes in excess of 2 %.
