Lu:
I don't know. wub could be right(Marconi/BAE).
Ignition Override:
My airline could just survive even taking into account limited knowledges and restricted capabilities of their Ckeck-and Training Captains. And yes, we heard about FMC and FCC once.
BTW: In this case Airbus calls the black box mentioned above FCC1 and FCC2. Look up AOM A306/A310 Chapter 3 "Automatic Flight." For you it might be confusing, but surprise surprise:
We also have a Flight Management System (FMS) to provide automation of flight management tasks on ground and inflight.
The FMS consists of two Flight Management Computers(FMC) and two Control Display Units(CDU). Airbus and Boing use nearly the same idioms and I had the pleasure to fly some of their very fine aircraft without getting confused.
Perrin:
Yes, slats and flaps are electrically signalled by two identical SFCC's(Slats Flaps Control Computers) The power unit motors for flaps are supplied by yellow and green hydraulic systems.
If you call that FBW, feel free. For me an aircraft is FBW type, if the primary flight controls in roll, pitch and yaw (ailrons, elevators, rudders) are controlled by computers and signalled electrically only.
UNCTUOUS:
It is a bit complicated. A Donald Duck explanation: it has to do with the PF who is pushing the yoke down while AP is trimming up more in AF mode(go around initiated by pulling TOGA levers), ending up in a high nose up condition and low airspeed. AP disengagement in due time would have prevented this. It happened to Interflug, Tarom and others who never reported after a lucky recovery. In some cases fatal. Try to find a link for you with a thorough finding. Sorry for Donald Duck.
Have a nice day
