Hi Byork, I have checked the FS2 crew manual but I do not see anytrhing relating to the key commands. I have had contact from Bryan and he told me that they have to be the same. I have sorted out the best way to install the MCP and FS2 Crew so that they gel as best I can but there is this problem with LNav,Lchange and taxi/landing light switches. I can carry out the commands verbaly but the FO does not turn them on or off he just tells me he has done it verbaly. I can not find a file relating to FS2 crew that I am able to check against the key commands of the MCP panel and change so that they are the same. I do hope I am making sense. Thanks a mill' for trying to help me.stupid me, just worked out your name. Thanks Bryan.
