Hi guys, I was flying from Zurich to Orly airport in a pmdg 777. I entered the waypoints in the MCDU, where the first waypoint from Zurich was VERBIT via VERBIT2N through the APP/DEPT page. The FMC shows the flight path, through the pink line which links the way points. However, once I activate the LNav button after takeoff, the airplane starts turning in circles but not following the flight path. Any ideas? Another question I have is regarding the LOC function. I was flying On an airbus x extended and was on the approach to Orly airport. However, I was taught to activate the LOC button to capture the glide slope. However, the plane starts turning and deviate from the flight path upon activation. Any ideas? Thanks guys! Anyway, do the pmdg 777 have the inflight announcement function like the airbus x extended?
