alf - "Checking landing distance for every approach" - a bit of over-kill there? I suspect Skyjob was looking at the "99%" routine landings which are conducted on familiar runways which are more than adequate (in good conditions) and where an 'early exit' is desired by ATC or taxi-routes? In these cases it is rarely necessary to spend too much time looking at 'runway conditions'/LDA since there is a more than adequate margin.
Obviously when things start to get 'tight' or 'dodgy' we need to take far more care (dare I mention 'airmanship'?) but as I say, 99% of the time, autobrake is an excellent tool for 'vacate at the second rapid exit' eg a 737 at LGW/LHR/CDG etc etc.
