I have been working on this non-stop for the past 18 days xml coding with a lot of help. The preflight popup is complete as is the P2 Audio Alert System programmed in xml by the dedicated work of EduHir from Austria at FSDevelopers. I want to give him a BIG Attaboy! here, those military know what that is, because with an 8 hour time difference between Austria and the U.S. East Coast he burned a lot of midnight oil with me testing, retesting, recoding etc. It operates exactly like the original because there were no limitations in the SDK. I have been programming this in Prepar3D V4.5 but will move everything into FSX with those models as well. There is NOW an almost vc because Milton Shupe's model will not allow me to remove the small portion of the panel in the interior model without losing ALL of it so it is what it is. I even was able to export an obj for GMax and work on it there but I don't know enough to export it properly so I just left it. I will be adding it to the Resources in both FSX and P3Dv4 after I complete the almost done 40 page illustrated manual which includes the real checklist which Mr Jim Savage furnished to me. I can see the "light at the end of the tunnel".
