I recently purchased the PMDG 747-400. I also have the PMDG 737 which I've had now for several Months. I had no problems with the FMC on the 737, but with the 747 I cannot fly a flight plan at all. Every time I click on the LNAV button to fly the programmed track I get an indication that their is a message for me on the FMC. I cannot view this message. The LNAV button never gets engaged to fly the programmed route. So far the PMDG 747-400 has been a big disappointment for me. Can someone please help me?

1. As per PMDG forum policy, please sign your name to a post2. LNAV will only engage if, from memory, you are on a heading of within 70 degrees of track. Read the manual to find the exact specifications3. The EICAS indication "FMC MESSAGE" means there is a message on the scratchpad of the CDU. The message you would recieve is "NOT ON INTERCEPT HEADING"Hope this helps

As far as the intercept goes I have intercepted the track several times by the use of the map, and it still will not intercept the track.Dan Owsley Jr.
