Bob Brown- <<When I was at British Caledonian, we rarely let an a/c leave the ramp if even one INS was u/s.
Bad Attitude policy was to let it go as they were still allowed to fly with one u/s.>>
Well BCAL weren't necessarily right were they- where are they now? I see nothing wrong with what you allege to be BA's attitude. One out of three U/S is no problem considering the Mean time between failures- losing another is extremely unlikely. When 2 are u/s, not the most sensible thing in the world despatching like that- trusting everybody to a single unit! You don't agree?
