According to EASA:
"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)"
This would imply that this planning requirement is only present for destination and any alternates. But the departure airport is neither. So to put it short any take-off alternate will comply but not the departure airport if we return immediately (as its not a destination or alternate). Right?
