If you're having unexpected issues with the A340-600, such as being stuck on the loading screen, deleting the compiled WASM modules may resolve this issue. This will force the simulator to recompile the WASM upon next loading the aircraft.
Deleting the compiled WASM and aircraft settings can be done by deleting all files within the aircraft WASM folder. The WASM folder will typically contain the following files, always starting with "m" aside from the work folder, but exact file names may differ from PC to PC.
The location of this folder will depend on your simulator and installation method and can be found below. Upon the next loading of the aircraft within simulator, these files will be recompiled, so you should expect a longer initial loading time of up to 15 minutes, depending on your PC specifications.
