VOR LOC disconnect on B737NG
That is the second time that happen to me.
AP B, ILS on active NAV2, VOR LOC armed (not clear for APP).
Not sure that is the reason, but seem to be linked, when the Capt set ILS active on NAV1, VOR LOC disconnect.
Try to find answers to this in FCOM, FCTM, even Goggle without success.
Nobody can explain the reason (may be the ILS selection but not sure).
What are the reason(s) a VOR LOC ARMED will disconnect?
Any clue is welcome.
Thanks in advance
