So flying around with the 777, and so far the things I've had trouble with are all with the MCP.

 

Aren't the buttons supposed to be on/off? I'm not at all able to disconnect things as A/P, LNAV, VNAV, HOLD

buttons etc. For instance, pressing Z to disconnect the A/P does nothing. The button is physically pressed, but nothing happens. The only way is to right click the hot spot beside the A/T button. Obviously that's not how it's supposed to be.

 

Any ideas?

You have to change modes or reset flight directors to deactivate the modes without activating another. For example: you can't just go from LNAV to nothing - it has to be either HDG/TRK SEL/HLD or LOC/APP.

And this is the way it was intended...?
