An "MCP" or (Mode Control Panel) is a panel in boeing aircraft for autopilot navigation. I know there are controls such as heading and altitude, and as commercial aircraft simmer, it feels a bit lacking - plus the inability to control speed at the same time with the current system..
This panel would allow you to control speed, heading, altitude and vertical climb rate, all on one panel. theses modes could be toggled as well.
Example: Having the aircraft hold altitude and speed, but you can manually control the heading. Etc.
