I’m puzzled by this photo of a 744 EADI/PND. 3rd Photo down at:
http://www.aerowinx.com/html/gallery03.html
Could somebody answer the following, as I’m not FMC experienced [yet] but would like to understand whats going on.
1.Is the white inverted triangle the actual a/c hdg?
2.Is the pink bug a selectable FMC hdg bug, and therefore the pink line from GGC the predicted track that it would fly if it followed the active route beyond GCC?
3. Am I correct in thinking that the FD is on [ie cross-hairs visible], the AP is engaged [ie CMD-green], and the FMC is active[ie LNAV+VNAV-green]?
By what means then could the trend vector be indicating such a left turn, the MAG-TRK not be consisitent with the FMC TRK, and why is the a/c not following the active route? Have I missed/not understood something[probably
]. Could this all be due to the turbulence?
