In aviation, the mode control panel (MCP) is an instrument panel that controls an advanced autopilot and related systems such as an automated flight-director system (AFDS).
The MCP can be used to instruct the autopilot to hold a specific altitude, to change altitudes at a specific rate, to hold a specific heading, to turn to a new heading, to follow the directions of a flight management computer (FMC), and so on.
The MCP often interacts with both the AFDS or autopilot and the FMC(s).
MCPs are usually found in advanced aircraft intended for commercial use, especially jet airliners.
They are often mounted on the glare shield, a small panel that overhangs the main instrument panel of the aircraft and also functions as a shield against outside glare.
