787 LNAV and VNAV toggle not working

Featured Replies

I am trying to fly the 787, but when I click the LNAV or VNAV buttons on the autopilot panel, they never activate. Other buttons like FLCHG do work. any thoughts? thanks. 

Are you by chance using the Heavy Division mod for the 787?  If not, it's a good thing and you can find it here:

Are you setting up the flight with a complete flight plan presumably?  If you've done that they should still activate, at least they did for me when I was using the default 787.  It's possible you are having an issue with misaligned clickspots, which is resolved by setting Lens Correction to OFF under General Options  > Graphics.

Do you have an active route and perf data entered in the FMC ?

Basic question I know but that would be most likely the real world culprit , though the 787 isn’t anything like the real world aircraft it must be said.
