The Battery (which I think was advertised as good for 45 minutes) lasted an amazing 1:40.....and then systems started rapidly dropping off line. The plane diverted to KORD and went off the side of the runway.
I'm not saying we need to know how to build the airplane, but the level of systems knowledge we now get is pathetic. It's going to bite us in the butt one day.
Well, here's a question, should you
not turn the standby power to ON?
Let's say you decide yes you will turn it on and now you're on battery, you realize you've got 45 minutes and you land 30 minutes later.
Knowing that if you turn that switch XYZ happens
is the new philosophy vs knowing that plus what the tire pressure is in the mains, how much of a certain quantity is required even though you can't measure it, knowing what temperature a valve opens when you can't read the temperature anywhere or how to draw this from memory...
I'm with you on not building the airplane. It's excessive rote learning. I think what they're pushing for now is more correlation than rote. And the people pushing this from the training house are not idiots about their aircraft and hoping to skip out on studying.
BTW, when I first heard it on the 767 that are knowledge needs to be 8 feet wide and an inch deep, I cringed. Then I looked at what they wanted you to know and realized it's more than an inch deep, but the focus is on correlating it.
Now if the checklist is a failure, that needs to be addressed. We need to know that the QRH is tested and trustworthy, because these are complicated machines and skipping a step might cause a problem with another system (something they may have figured out in the sim when they wrote it), or you might forget to go back to what you skipped, etc. It's kind of like taking something apart, putting it back together and have all of these "spare" pieces.
