LNAV HDG not following flight plan
After I engage the FMS which indeed is working because I see the VORs, NDBs, etc displayed in the PFD and MFD descending distance as I fly. I engage the NAV button. So I have NAV, HDG, ALT, BNK, YD and FD1 lit on my autopilot section. It shows LNAV HDG <--- ALT or TO. It is definitely TO when I engage the TOGA on the throttle prior to departure. <I HOPE IM EXPLAINING THIS CORRECTLY> When I engage NAV the LINE showing between the waypoints on the MFD is still magenta. Same color when I engage FMS. According to the manual the line should be white. Is this why the autopilot is not following the flightplan flightpath. The reason I am asking is because sometimes when my plane appears to be within the flightpath, RADAR CONTACT says I am deviating my flightplan or flightpath. I want to make sure I am following protocol in use of the autopilot before I start bellyaching at the RADAR CONTACT forum.
Thanks in advance!
