Title: DONE - LNAV random disconnects itself
Post by Krake802 on Jul 6^th, 2021 at 11:26pm

Hello,

During cruise today, on 2 different flights I was half way through my flight with VNAV/LNAV on (As you would) and my aircraft on 2 different occasions missed a waypoint and continued to fly present heading rather than turning to the next waypoint.

Once I noticed it did this, I had to direct to the next waypoint closest to me, it never did it after.

Still shouldn't be happening...?

Hello,

I have exactly the same problem, and always have to capture the missed wayponts manually. This is very anoying!

I also have the same problem. It simply ignores the waypoints.

Hi!
Are you sure no inputs on the yoke when LNAV engaged?
One input on this cause a disconnection of LNAV mode and show a message on EADI screen.
