Anyone know what is feeding the two NAV sources along the bottom of the MFD in the F-15E - TCN on the bottom left and NAV on the bottom right. They are moving/changing as I fly but it is not obvious what they are tracking. I am using a NAV plan generated within AFS2 and manually following the green route at the top right. Can these NAV displays be used somehow as part of the navigation until the first update comes along?
Regards.
