I am implementing a system soon to MD-88, MD-90, and A320Family. (possibly more)
This system allows many advances.
The new Aircraft Config dialog allows:
Changing Livery
Loading fuel/payload (not implemented yet)
Loading Panel States (cold and dark, ready for taxi, etc...) (in progress)
Aircraft Help and Training (not implemented yet)
Ground Services (will be in main dialog soon)
Changing aircraft settings (retrofit, INS vs FMS (when available), autobreak available, etc)
Loading aircraft settings from livery (so livery makers can put the options the real plane has, and when that livery is selected, those options become active
And more.
Panel states will only work on planes that I develop solo, as I build the systems to work with panel states. (MD-88/90 A320Family)
The basic dialog is here. However, more buttons and options will be added not long from now.
All 4 Panel states are working!
I am planning to make Ground Services, and possibly Select livery available in this box, without another click to pop them up.
I also have made a BRAND NEW engine system for YaSim. The plane can more or less be manually started somewhat realistically. (still alot of work to do, but whats there, does work correctly, and realistically.)
Will be pushed in less than 2 hours from this post.
Regads,
Josh
