Can't Engage VNAV

Recommended Posts

I just started flying the PMDG 737 a few days ago and for some reason, I am not able to engage the VNAV, however, I am able to engage the LNAV. I have tried reading other topics but I couldn't get a clear answer. I don't know if I'm doing something wrong. I set my flight plan in the FMC and I have set the trim as close to the setting as the FMC recommended. Any help is appreciated. 

 

(Side question, when I use the base PMDG 737, it give me a newer looking cockpit, but when I use it with different liveries, it uses a different cockpit. Could there be any reason for that?)

 

I hope I did my signature correctly, because I have read that you have to put your first and last name.

Yes. This is explained in the Intro Manual. Please take a moment to read it.

ok. I read it. So you have to exit out of FSX, go back in, and then choose the livery or do you exit out, go to the PMDG operations center, change the livery, and go into FSX? I'm a bit confused.

No. There's an entire section on livery options. Basically, since the real aircraft have hundreds of options: MCP type, derates allowed or not, carbon brakes vs steel, and so on, we've allowed people to select a number of them. Most liveries comes with those options set to how they would be in the real aircraft.

 

For what it's worth, the Intro Manual (along with the first tutorial, I believe) explain your VNAV issue.

In addition to reading the Introduction Manual, you should fly Tutorial 1 if you haven't done so.

Make sure your PERF INI page is complete and your A/T is on. However do fly the tutorials as advised.

Not able to engage VNAV usually means your weights and fuel load are not set correctly. As Alberto mentioned, the PERF INI page. As others have mentioned, run though the tutorial flights, they teach you a lot about setting the aircraft up and flying point A to point B.

I don't think A/T is required for VNAV. It certainly makes it easier, though!
