    During one of my flights, I lost my altimeter and eventually my airspeed indicator. Subsequently, I am not even able to adjust the altimeter while on the ground with the engine off. I can spin the dial and the pressure moves, but the needle just sits there. Also, the airspeed indicator just sits.

    Edit: I should add that I have reinstalled the aircraft and I still can't get the instruments to work at all.

      Update . . . I went back into the simulator and did a complete overhaul on the tablet. It worked. I was able to adjust the altimeter and got airspeed and altitude working. Unfortunately, on my very next flight, the same behavior has repeated itself and the overhaul didn't work.

        That sounds like a failure may have occurred (as part of the Maintenance simulation in the PA-38 Tomahawk), and the state saving is causing it to be recalled on future flights. In MSFS 2024 specifically, there is some instability with state-saving logic in the core simulator that could be causing this, but it may also be caused by how a flight is ended in the simulator. We would always recommend exiting a flight via '[ESC] > Main Menu', rather than forcing the simulator to close with a shortcut such as '[ALT]+[F4]'.

        If the same failures continue to be present at the start of every flight after ending a flight via the above method, I would recommend deleting the WearStates.ini file from the relevant file directory below, and it'll then regenerate the next time a flight is loaded with the Tomahawk's default wear state, with no active failures:

        MSFS 2020 - MS Store:
        C:\UsersUSERNAME\AppData\Local\Packages\Microsoft.FlightSimulator_8wekyb3d8bbwe
        LocalState\packages\justflight-aircraft-pa38\work\Wear

        MSFS 2020 - Steam:
        C:\UsersUSERNAME\AppData\Roaming\Microsoft Flight Simulator\Packages\justflight-aircraft-pa38\work\Wear

        MSFS 2024 - MS Store:
        C:\Users\USERNAME\AppData\Local\Packages\Microsoft.Limitless_8wekyb3d8bbwe\LocalState\WASM\MSFS2024\justflight-aircraft-pa38\work\Wear

        MSFS 2024 - Steam:
        C:\UsersUSERNAME\AppData\Roaming\Microsoft Flight Simulator 2024\WASM\MSFS2024\justflightaircraft-pa38\work\Wear

        Hope that helps.
