QOTS II Autopilot Malfunction

Featured Replies

During my last two flights flying the QOTS II B747-400 the LNAV or Heading Mode Annunciator on the PFD, depending on which was selected, has come up with a horizontal yellow line through (indicating a malfunction), the shortly after this the autopilot has disconnected. The first time this happened was after about three hours into the flight. Yesterday it occurred after about 10 minutes into flight.

I am thinking of deleting the aircraft .cfg file - would this be a reasonable attempt to cure the problem?

Hi,

 

I dont think so. Deleting that aircraft.cfg will likely screw things up because that file wont re-generate automatically since thats a config file for the PMDG aircraft itself. If you were to delete it I think you are looking at re-installing the PMDG aircraft completely.

Did you take a look here? This is similar to the problem you described. Its certainly odd that this would occur mid flight. Have you plugged in any new hardware into the sim recently?

 

Regards
