I'm not sure if this has already been asked, but does anyone know what the C/O button on the MCP does? I've looked in the operating manuals and I can't find anything on it.Regards,

What Google can do for you:C/O ButtonThe Change Over button is used to toggle the speed display between IAS (Indicated Airspeed) andMACH (Mach Number) readout.

It's the changeover button. Allows the pilot to manually switch between Mach and IAS modes. See FCOM V2, page 4.10.2Kevin Hall

Use it above FL260 when the VMO changes to MMO.
