VOR tracking at 767
Could anybody spread some lights for limitations of autopilot VOR tracking at B767, I've heard that it only allowed for tracking (ILS) localizer only and if you require track VOR radial you should use FMC (put NAVAID ID / required radial ) or make it manually via HDG SEL following to HSI or RMI indications, in other words there isn't capabilty to tracking VOR by autopilot using both NAV VHF receiver, does it really true??
Thanks in advance
