s&t,
Before you bring brake cooling into the equation - I assume that you know the difference between "2 engine reverse" & "no reverse" brake cooling schedules?
63 T, 20 deg. C, 140 kt brake-on-speed, A/B 3 and 2 engine reverse gives me 20 min. brake cooling turn-around time, but hey, what do I know? I'm just an overpaid busdriver!
Before people launch into more uninformed speculation - could we please leave it to the 73-drivers to comment on specific operational procedures and problems and leave the general comments to everyone else?
