sevenstrokeroll;
and where inop anti skid REALLY GETS YOU, is if you reject/abort a takeoff with anti skid inop.
Echoing IGh...yes indeed, given that antiskid brakes are the only basis for the certification of performance during a rejected takeoff. While the MEL may provide numbers for longer distances, this would place most crews who actually had to reject without antiskid, in test-pilot territory.
Dispatching with anti-skid u/s is a serious matter which requires much thought before accepting the airplane and thorough briefings. Can't recall for the B727/B767 regarding brake pressure information but the Airbus series provides pressure indications which must be kept below 1000psi when the antiskid is u/s, which the PM monitored and called out if the pressure was getting close to the limit. Works well on the A330...
