KSJ, the latest SimApp Pro (.67) just released by WINWINGS yesterday provides full functionality of all released WINWING Gear, FCU, EFIS and MCDU. Just like the Fenix Airbus, one only needs to use one app for full functionality across this suite. AFAIK the Fenix planes and now the ini a340 are the only aircraft to achieve this type of integration and I have multiple WINWING products for my many, many planes.
Be aware tho this is a WIP for both ini and WINWINGS. The SimApp Pro released yesterday will probably need an update/fine tuning and ini commented on their discord yesterday they still have a bit more work to do before 100% stability is achieved.
Convo starts here on Ini-general discord. Much discussion and info to be found. Blue skies and good luck,
