These statements are false and/or incorrect. They're not mostly incorrect......they're not incorrect when only used by Lufthansa staff, they're incorrect period! Albert and Salton gambled with their choice of words and got called on it, nothing more or less. I'd say their communication skills probably improved today. EDIT: I'm quite sure you're not ignorant Andrey, quite the opposite actually and I'm sure you have quite a bit of helpful knowledge given your experience. I tend to be a "stickler" for communication and choosing one word over another or not saying exactly what you mean can cause confusion. Let's look at the entire quote: Please be sure carefully that all mentioned in your picture switches are correct. It's a "Boeing Policy" - switch positioned DOWN - is ON, UP - OFF. But how your switches positioned is wrong. It was revealed that: When Lufthansa planned to buy a large amount of 737´s in the 80s, they asked Boeing to reverse the switch direction. I think it was due to a perceived "human factor" preference of moving switches "intuitively". I you want something, you "pull" it towards yourself. Hence the on position = aft. In other words, he was entirely correct: the Lufthansa preference is wrong for Boeing policy, and was something requested by Lufthansa. Furthermore: Interesting fact - when other airlines train in our simulators in Frankfurt, the simulator technicians actually switch out the overhead panel for the Boeing version. And, finally: Right, we offcourse had this discussion in the team already.We came to the conclusion that after everything Jan and LH are doing for this project it was an easy choice. So, the Lufthansa was is wrong with respect to normal Boeing SOE. Morten and friends know this, and their choice was conscious. I have no idea what you're going on about. Furthermore, this is a stupid thing to argue about, and I'm finished.
