I've been meaning to ask this for a while--on the below 777 cockpit photo, the LCD display screan frames appear to have a hinge of some sort, but only at the bottom. The fact that this "hinge" doesn't have a corresponding one on the top leads me to believe that it's not a hinge. So what is it?

If you look closer, the bar on the bottom is raised, as it's seperate from the whole frame.

Unscrew the screw/knob on the right of the hinge and you can flip it open to get access.

Remember, taking off is optional, landing is mandatory.

Our B777 have cathode ray tubes., not LCDs. But the whole unit comes out. All 6 screens are the same so can be interchanged if one fails, to comply with the MEL. They slot into a frame with fitted connectors.

Feel free to correct me but... aren't all 777 flight decks equipped with Honeywell LCD screens ? I think it was even a Boeing argument in the 777 design phase, that LCDs are lighter than CRTs, due to the fact that the first generates less heat than the second, meaning that it needs a lighter cooling system.

Best regards, GearDownPlease

Yes you are right. I stand corrected. I had to look in the AMM to check. The reason is when I interchange them they are so big and heavy I assumed they are CRTs. They are 8.75in deep 8x8 in screens and weigh 18lbs.

Can the Screen in off position give a sign if a display unit is a CRT or LCD.Any way of telling.
