Autobrakes alone.... "The IRUs aren't mentioned in the A/B switch (1~MAX) arming logic on the 747-400."-- Look again.
oops... missed that one. Maybe I was looking at RTO. I'll amend my message if it's not too late.
I think we need someone with some free sim time to chime in here. i.e. prior to arming autobrakes, put the IRU's to ATT.... look for antiskid messages, then ARM the A/B's.
