Landing distance question
Hello folks,
i have a quick question concerning landing distance. Im actually a little bit confused.
Letīs take a runway which shows on the approach chart 2500mX60. So we want to land there and im getting a landing distance required of 2050m. Well, definition of landing distance in my opinion is: 50ft over threshold, vref, max manual braking , isa , etc (actually conditions are not important for my question) so i brief, we have a 2500m long runway we need about 2000m so we can afford a little flare right?
So the discussion was: the 2500m with no displaced threshold is the LDA, landing distance available. So we fly over the threshold at 50ft and then it starts right? My team member said that thats not correct, in fact we land at the 1000ft point so actually we lose roughly 300m at the landing. is that correct? in case of displaced threshold, well yes but without a displaced it counts right?
