Follow-up post on previous topic (16384!=16383)
Long live ‘FSInterrogate‘ (a tool that can read FSUIPC offsets): when launching P3D in virgin modus (i.e. just start a new flight without sending any further commands), FSUIPC always returns ‘16383’ when the wheels are down.
Probably FSUIPC is indeed not so strict for what concerns the values being sent.
Conclusion: the example code delivered with the SDK works, but is not 100% correct. That makes it a bit harder to understand how everything works, but… without the code it would have been even harder 🙂 .
