1) your instructor is talking crap.
2)if you lose an engine ,both fds are working.
3)if you lose one gen,the autopilot can still be engaged on the failed side until you select the apu gen on,it will disconnect and you can then reconnect it...messy though.
4)if an fcc fail,its fd will fail.
5)if fcc A fails,you can not engage A/P A ,if FCC B fails,A/P cant be engaged.
