Hey guys!Hope all is well.Yesterday I was flying a leg from VIDP to LLBG on board the 737-700 when I ran across a problem while in cruise flight.The aircraft flew over a waypoint on the route and started banking a 360 degree turn and didn't stop turning.I tried to manually go into the FMS and double clicking the next waypoint so the aircraft could fly direct the next waypoint and it didn't help. The aircraft kept turning to the right. Fuel an everything was perfect and no other issues were detected.LNAV was enabled.This happened about 4 hours into the flight.The waypoint was OK and there was no weird route on the FMS.What could it be?Thanks much in advance.Teo

Were all the discontinuties fixed from the legs page?- John

Everything was ok, actually it was inside the route itself and there were no discontinuities.Very strange behavior...Teo

A Disco wouldn't cause the 360, I don't think. It would just drop out of LNAV.
