To add something else, it says in my preamble for dispatch..
4.2.2 USE OF QRH DISPATCH LANDING PERFORMANCE DATA
To satisfy the Air OPS, prior to dispatch (planning stage) or in the event of in-flight replanning, determine the Max weight at which the airplane can land at destination or alternate airport within available landing distance in expected conditions. LDR must be equal or less than LDA.
MAX weight? I thought requirement is you use estimated landing weight to determine 60% of LDA?
Also it says LDR must be equal or less than LDA. Surely if during dispatch LDR equals LDA you'll be above 60% of LDA?
CAT.POL.A.230 Landing—dryrunways
(a) The landing mass of the aeroplane determined in accordance with CAT.POL.A.105(a) for the estimated time of landing at the destination aerodrome and at any alternate aerodrome shall allow a full stop landing from 50 ft above the threshold:
(1) for turbo-jet powered aeroplanes, within 60 % of the landing distance available (LDA); and
