OK re-assigned the flap lever in FS and that now works. The only minor glitch is the AP annunciator on the PFD. Now I can switch it off with the mouse and I get the chime and the AP will go from green to white and then yellow. Although I get the AP disengage chime using the Bravo panel switch and the panel switch light will go out, the AP on the PFD remains green.
Oh and landing gear worked when I switched to another plane to test that.
All in all a great little app that gets rid of that blasted heading bug.
So thanks very much, it should be advertised on the main community thread to let more people know.
Pity I don’t have any .NET experience or I might be of some help with debugging the alpha and bravo combo.
