Hi A33Zab, thanks for reply - that sorts it out
I undestand that the kind of failure required to lose the CG info on the A330 is fairly remote. OTOH, on the 320, FAC1+2 Fault and Gear Down should be enough if I understand the system correctly...
What about FCPC gains variability with respect to S/F position? Why is that implemented? Is it due to additional pitch authority required co counter the pitching moments after S/F extension? (though this should be catered for by the THS if available) Or are there some other considerations?
