AMC1 CAT.POL.H.310(c)(2) and CAT.POL.H.325(c)(2) Take-off and Landing    

CAA ORS9 Decision No. 1

FACTORS

(a) To ensure that the necessary factors are taken into account, the operator should:

(1) use take-off and landing procedures that are appropriate to the circumstances, and that minimise the risks of collision with obstacles at the individual offshore location under the prevailing conditions; and

(2) use the aircraft flight manual (AFM) performance data or, where such data is not available, alternative data approved by the CAA, which show take-off and landing masses that take into account drop-down and take-off deck-edge miss, under varying conditions of pressure altitude, temperature, and wind.

(b) Replanning of offshore location take-off or landing masses during the flight should only be performed in accordance with procedures established in the operations manual (OM). These procedures should be simple and safe to carry out, with no significant increase in the crew workload during critical phases of the flight.
