Gidday guys after much trial an error an also scrolling these forums for hours i cannot seem to find a solution to my problems..I cannot get the L NAV to track my flight plan..After reading these forums an finding out how to load my route properly into the FMC i thought i was set to go..I take off track runway heading than i hit L-NAV an V-NAV the V-NAV is doing its job but the L-NAV fly's the runway heading.. Ive tried manually setting the heading to my 1st point in the flight plan an still get no joy everytime i hit the L-NAV switch she wants to go back in circles an track the runway heading..My flight plan goes:YSSY 34R than my SID normallyEntra 2DIR -ENTRADIR - WMDDIR - BANDADIR - CGSTAR CG.8 RW 01Any advice would be greatley appreciated..Julian..

Do you not Arm LNAV & VNAV before departure. If you do that then the aircraft will follow the route.
