FMC and Autopilot in 767 PIC

Featured Replies

I am new to 767 PIC and couldn't get it to work with FS2002 for quite a while. I did a reinstall of both and now it is working fine. I do have a question about the relationship between the FMC and the autopilot. I know this is probably an obvious question, but I can't seem to find an answer in the FMC Manual (which I printed out). It only makes sense to me that the FMC and the autopilot are linked in some way. If I program the FMC for a trip and activate it, how can I link this trip to my autopilot so that that the airplane will automatically fly the coordinates punched into the FMC? Is this automatic when I program the FMC and then hit autopilot? I tried this but it did not seem to work. I am sure there is probably another switch or two that have to be thrown for the link to happen. Or is programming and activating the FMC enough to fly the plane based on the flightplan put into the FMC. Thanks for any help. Sorry if this seems like a simple question, but the 767 PIC and FMC manual are a bit overwhelming at the beginning.

Hi "Nyrxman"There are in fact two switches on the MCP (autopilot panel) that links the autopilot with the FMC. They are called LNAV and VNAV.LNAV provides lateral guidance (roll) while VNAV provides vertical guidance (pitch). For further explanations of these two modes I suggest you read the manual, as is far too complex to explain in one post.Good luck,RegardsMark

Also to add to what Mark has said, what altitude you have set on the MCP panel works with the FMC. If you are climbing with VNAV to your cruise altitude you will want to set the MCP to that altitude and the same when descending. It takes a bit to learn how it ties in together but is really rewarding when you get to that point. Best Wishes, Randy J.

sugegst u use FLCH, i find it to more efficientcheers

If, in the real world FL CH was more efficient than VNAV, then why do airlines use VNAV over FL CH? Many pilots here have stated that they do use FL CH at or below 10000' and for small altitude changes they will either use VS or FL CH but for climbing VNAV is the most efficient means.
