Before FMS was first introduced into TriStar operations - we were very happy with Radio Nav (VOR etc) around Europe, INS display for Long Haul Ops, (Cross Track Error & Desired Track) & Manual Thrust in the cruise everywhere. After the intoduction of FMS, some wondered how we had coped before hand.
Only Airbus could design an aircraft which fails the autopilots when the FMGCs fail though.
