yes. But the autopilot should not be unable to fly it as well.
As soon as I turn the FGMC, my computer is unable to keep running FG.
The FGMC helps pilots to fly a plane. It DOES NOT take control over the plane, as it does with this model
(with this I am saying, the plane should be flyable, with FGMC OFF as well. Not fully FGMC dependent. Notice I am not referring to Route Manager)
Also, I use to have several hours on this plane. It used to work. With FGMC and Without FGMC, via the cockpit AP.
Finally; NAV1 was not switching to someting programmed in the FGMC. It was switching to a random VOR in the vicinity of the aircraft position. And completely disregarding the frequencies indicated by the pilot. NAV2 was ok; preserving the set frequency.
