This driven me crazy for a while, as I was not aware of this problem. Basically both are not compatible. In the case of DC-6 using FS-FlightControl produces that gauges and engine stress info in the tablet rapidly oscilate all the time and also a flickering low oil pressure annunciator that never turns off. This is specially critical if you have enabled the realism settings in the tablet as it leads to engine failures short after takeoff, making it impossible to fly the DC-6 with realism enabled.
If you face this problem while following the right procedures for this plane then FS-FlightControl is most likely the reason.
But I have found that the problem is reproduced only during aircraft initialization and engine start. Therefore you can still use both if you follow these steps:
- Quit FS-FlightControl before launching the flight from MSFS.
- Once in the cockpit perform the engine start procedure on the DC-6 without FS-FlightControl. Engine start can be done manually or using AFE if you prefer.
- Once you have your engines running and you are ready to taxi you can manually launch FS-FlightControl again.
You need to quit FS-FlightControl before every new flight with the DC-6 and repeat the steps above.
This has worked for me so far and yesterday I could complete a 2h flight with all realism settings enabled without any issues for the first time. In my case I just used AFE for the preflight checks and did all the rest manually.
If for some reason you see rapidly oscilating gauges, oscilating engine info on the tablet or flickering low oil pressure annunciator in the cab that´s FS-FlightControl again and this will lead to an engine failure, no matter what you do, so you will need to quit it again and continue flying normally. I just had problems during engine start so I never needed to quit it again afterwards.
