GM1 CAT.POL.A.330 Landing — dry runways

CAA ORS9 Decision No. 15

LANDING MASS

CAT.POL.A.330 establishes two considerations in determining the maximum permissible landing mass at the destination and alternate aerodromes.

(a)    Firstly, the aeroplane mass will be such that on arrival the aeroplane can be landed within 70% or 80%, as applicable, of the LDA on the most favourable (normally the longest) runway in still air. Regardless of the wind conditions, the maximum landing mass for an aerodrome/aeroplane configuration at a particular aerodrome cannot be exceeded.

(b)    Secondly, consideration should be given to anticipated conditions and circumstances. The expected wind, or ATC and noise abatement procedures, may indicate the use of a different runway. These factors may result in a lower landing mass than that permitted under (a), in which case dispatch should be based on this lesser mass.

(c)    The expected wind referred to in (b) is the wind expected to exist at the time of arrival.
