I am struggling to calibrate my throttles?

[iniBuilds]

Firstly you must establish if you use reverse thrust on an axis or not.

If no, ensure this is set to NO on the EFB and calibrate as per the instructions on the calibration menu. Reload the plane to ensure this change is made properly, and you will be able to bind reverse thrust to a button / input on your hardware.

If yes, and you do intend on using reverse thrust on an axis, ensure you set this to YES, and calibrate as per the instructions on the calibration menu.

Reload the plane to ensure this change is made properly, and you will be able to use your reverse on an axis with your hardware.

So to all having throttle calibration issues / if you know others who have it please let them know. We have made a fix code side but as a temporary workaround on TCA units:

Paths:
MS Store version: C:\Users\yournamehere\AppData\Local\Packages\Microsoft.FlightSimulator_8wekyb3d8bbwe\LocalState\packages\microsoft-aircraft-a310-300\work

Steam: C:\Users\yournamehere\AppData\Roaming\Microsoft Flight Simulator\Packages\microsoft-aircraft-a310-300\work

Steps
Locate your ThrottleConfiguration.ini file, open it and set both reverse_idle entries to a value that is 0.05 less than your idle value. 
Example: 
[throttle_common]
reverse_on_axis = true

[throttle_axis_1]
reverse_full = -1.000000
reverse_idle = -0.200000 -> Change to -0.45 because (idle is -0.39 - 0.05 = -0.45)
idle = -0.396667
toga = 1.000000

[throttle_axis_2]
reverse_full = -1.000000
reverse_idle = -0.200000 -> Change to -0.45 because (idle is -0.39 - 0.05 = -0.45)
idle = -0.395569
toga = 1.000000

[throttle_axis_1]
reverse_full = -1.000000
idle = -1.000000
toga = 1.000000

[throttle_axis_2]
reverse_full = -1.000000
idle = -1.000000
toga = 1.000000
