NigelOnDraft;
If I want to know how much runway the aircraft is actually going to take to come to a full stop from a height of 50ft, I would consult the "Actual Landing Distance without Autobrake - Config FULL" to get an idea of what a very aggressive approach/touchdown would produce - (the landing is, as you know, practically no flare and max braking to a full stop, engines in forward idle thrust the whole time). Then I would consult the "Actual Landing Distance with Autobrake - Config FULL or Config 3" to see the effects of Brakes LOW and MED and the reduced flap configuration. Neither chart takes into account or requires the use of reverse thrust.
Our charts must be different to yours
We only have "A320 Ldg Dist without Autobrake" which state "..assume max Manual Braking
and maximum reverse thrust".
We then have some "Autoland" charts and correction factors...
