I don't know about the whole removing the electrical devices thing, but we can lose the FADEC system and it goes into a reversionary mode. If that mode fails, then we just land. We could likely still fly, but it's just easier to land as soon as possible.
The fuel pumps are actually in the tanks, along with the engine driven fuel pump. We can still fly below 6000 ft PA with the fuel pumps inoperative because the engine driven pumps are so efficient.
The entire aircraft is pretty complex, one of the reasons I love it so much. I like tinkering with things, so it was a perfect match for me when aircraft selection came around. To us, all other aircraft are nothing but slingloads!
I'll take a pic of us fully armed when I get out to the flight line tomorrow. Pretty impressive. Now flying while the gunners are engaging gets the adrenaline going quickly!
