Shouldn't this be in "Tech Log" ?
Anyway, don't have a manual to hand either, but my recollection was that max manual braking was shorter than autobrake in MAX, as MAX was still a deceleration rate, rather than truly maximum braking.
However, I always believed that RTO was the equivalent of maximum manual braking, have I been believing the wrong thing for 22years ? Duh ! or has it been wrongly described in manuals at some stage in the past.?
