Mr Dowson,
I am having a strange issue on MSFS, or maybe on FSUIPC these days . I have FBW A320, LSH Maddog MD82, PMDG's B737 and JustFlight's BAE 146.
I have an application which extracts data from FSUIPC via FSUIPCclient.dll. The problem is, these aircraft suppress each other's LVARs. For example, when I start with FBW A320, everything works fine, then I change the aircraft and select another one, say it is MD82, the application can not find MD 82's parkbrake LVAR, seatbelt LVAR etc.
You disable other aircraft by using MSFS Addon Linker (another application), start the MSFS, start MD82, this time everything works fine.
You enable FBW A320, start MSFS with FBW, this time FBW's parking brake LVAR can not be found. MD82 works fine.
When an aircraft works fine, the others don't. If you disable all others and enable only the one you will fly, it's ok. What might be the problem sir?
