Within 60% of landing distance
Firstly I have searched extensively through old posts and have failed to find the answer. Some post came close to the answer I am looking for but for some reason I’m still not quiet getting it.
My question:
According to CAT.POL.A.230 Landing-dry runways it states:
(a) The landing mass of the aeroplane determined in accordance with point 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 turbojet-powered aeroplanes, within 60 % of the landing distance available (LDA);
So for example:
LDR= 1200m
1200 x 1.67 = 2004m
Runway= 3000m so no problem I can land.
Now if I read the above statement word for word. ‘Within 60% of the landing distance available (LDA)’
60% of my 3000m runway = 1800m.
Can someone explain what I’m missing here?
