Hello,

First of all, thanks to Markoz for this great Tutorial  :)

The reason because I read it, is that because I always load a Standard-FSX-Plan into the FMC.

BUT, before each waypoint (between ~50 to 120 nm) LNAV disenages and the plane turns uncontrolled to the right or left. In this case I have to quickly switch to "HDG SEL" to stay on course.

When the next WP was passed and I reengage LNAV all works fine til to the next WP  :-/

Any idea what is going wrong? Can it have to do with that I load the plan also as "normal" into the Sim (not only into the FMC)?

I don't care about SID or STARS, I only want to follow my own created Waypoints between 2 airports.
