Just to give an example all dials and switches will be activated in the same way on all 7E7s. If you flip a switch towards the front of the plane to turn X function on on an AA 757 and you flip it towards the tail to turn in on on a TWA 757 that will not be happening anymore on the 7E7s.
I'm quite sure it will. Boeing can say anything they want (though I haven't read this anywhere); they're not going to tell AA
"no" if they ask for the switches to go in the other direction to match the rest of their fleet. Here's how the conversation goes:
: "We're thinking of buying either 50 7E7's or 50 Airbus A350's. Can you make the switches go the opposite way in the cockpit for us?"
: "Ok, we'll give our money to Airbus."
Boeing: "Wait, wait! Did I say no? I meant yes!"
I'd like to read exactly what you read about this. I know Boeing has been talking about a "standardized" cockpit for a long time, but that just means it's standardized between their different models. So, for example, a pilot could be trained on a 747-400 and require minimal re-training to move over to a 7E7. Where possible, they could be type rated on several different models of Boeing aircraft, which makes it more likely that an airline will stick with Boeing throughout their fleet.
If an airline placing a big order wants knobs instead of switches, or if they want switches that go in the opposite direction, or if they want bigger fuel tanks, or if they want different engines, Boeing's going to figure out a way to give it to them. They're in business to make money, not to teach airlines a lesson about standardization.
