Techman,
Three cheers!
What is even worse, is there does not seem to be a place to go look it up either! While the aircraft systems of today can be so interconnected, it would be impossable to keep them all straight during an oral or PC, it would be great to have a "reference" manual that tells the real story.
It seems the older aircraft were built on the thought that the crew would be smarter than the aircraft, and today's aircraft are built on the, oh never mind.
By the scope of this thread, I assume that the cause of the triple failure is running all three systems dry. I'll see if I get some time in the simulator next week and see what ours does. I agree it might not be completely correct, but since the simulator models what happens with each system dry, it should be able to do it with all three empty. Also, some simulators have the real computers, they are just feed inputs.
