I apologize if this has previously been visited, but what causes the FMC Course Error message during the approach?I don't get it during every approach and it's not a big deal. Just wondered if anyone else has experienced this andwhat can be done to prevent it.Thank you,Ken Boardman

Hello Ken,To put it briefly, you have to dial the runway course that appears on the APPROACH page for the given runway in your MCP. They may be a degree or two different from real life charts (if you are setting those ones) depending on your Airac cycle.

Thank you for the tip Onur. I'm eager to try this a few times and see what happens.Best regards,Ken Boardman
