PMDG 737 Engaging N1 on VNAV Approach (SAN RNV27)

Featured Replies

My PMDG randomly decided to engage N1 in the middle of my RNP approach, Help?

Sorry, what do you mean by engaging N1?

N1 as in applying max amount of available thrust related to what you set in the N1 Limit page on the FMC before takeoff.

I see. Sounds like the issue is that the autothrottle is providing max thrust. Is it a temporary thing (meaning it lowers the thrust back down) or does it apply max thrust and maintains it?

It holds the power and completely deviates from the speed bug, also over speeds.

Sounds like it somehow commenced a go around? Maybe a keybinding issue here?

Got it. I recommend watching 737NG Drivers VNAV/LNAV tutorial. He explaines how to work the MCP during the approach to keep the AP from capturing the altitude when reaching minimums. Sounds like thats whats happening to you.
