As far as I know, once the 747 classics retired, all BA fleets flew the standard BA approach, and I'm fairly certain the the chief pilot 747 Classic at the time regretted not having forced the issue when the NO incident occurred.
Not quite true. The 747 Classic introduced the monitored approach several years before the classic retired. They also changed things and made the non-handling pilot select reverse thrust. All fleets did not fly the standard BA approach as Concorde never adopted the monitored approach.
As for the NO incident, so many factors involved in that, but for autolands as the Captain took over at 1000 feet radio post monitored approach or maintained control at 1000 foot radio pre monitored approach I do not see much difference as the Captain would have been the handling pilot below 1000 feet radio with either method.
