Another consideration relates to LVPs ... the use of autobrake greatly simplifies the pilot's workload in maintaining centreline during either RTO or landing if the visibility dies .... in a recent contract during sim training for LVP ops, I had pilots doing raw data handflown ILS to a stop in 0/0 for stick and rudder practice ... not too much trouble with autobrake on ... but much more demanding using manual braking due to the very fine localiser tracking needed to maintain a reasonable centreline ...
