If you are using the Honeycomb Bravo or Thrustmaster TCA Throttle Quadrants you may run into an issue where only 2 of the throttles are moveable in the aircraft. This is due to the Honeycomb Bravo and Thrustmaster TCA Throttle Quadrants using control assignments in slightly different ways, and therefore, the same control assignments cannot be used in the same way for both throttle quadrants. In the 146 Professional, the control assignments that are most likely to cause a conflict are the "FUEL VALVE" control assignments which move the throttles in the aircraft between the FUEL ON and FUEL OFF positions.
As a workaround for this, we have added an option in the 'JF_146.ini' file so you can configure the 146 Professional for the hardware you own. The 'JF_146.ini' file is located in one of the following file directories, depending on which version of MSFS you own:
Microsoft Store Users:
C:\Users\[username]\AppData\Local\Packages\Microsoft.FlightSimulator_8wekyb3d8bbwe\LocalState\packages\justflight-aircraft-146\work
Steam Users:
In the 'JF_146.ini' file, scroll down to find the following parameter:
THR_LATCH=0
'0' is the default value and is compatible with the Honeycomb Bravo Throttle Quadrant. Changing this value manually to '1' will provide compatibility with the Thrustmaster TCA Throttle Quadrant. A restart of the simulator will be required in order for any changes made to the file to take effect.
