From Jeppesen introduction:
LANDING DISTANCE AVAILABLE (LDA) (ICAO)
The lenght of runway which is declared available and suitable for the ground run of an airplane landing.
lets have a look at Amsterdam (Schiphol)
RWY LDA RWY
01L 9350 10827
19R ------ 10827
01R 9268 11155
19L 9268 11155
06 10663 11483
24 -------- 11483
The landing distance is from the threshold or displaced threshold to runway end.
Amsterdam has displaced the threshold of rwy 01L, 06 and 19L.
Note that LDA of rwy 01R is not the same as the rwy length and it does not have a displaced threshold. This is due to (as the note says) "For normal operations LDA 9268 ft. In exceptional cases the additional pavement of sufficient strength of 1887 ft beyond the red rwy lights is availble on request"
so LDA is from (displaced) threshold GREEN CROSS LIGHTS to the runway end RED CROSS LIGHTS.
Hope this helps.
