S!
Thank you for the answer, that covered it all. I agree on the checklist etc. IT is a lot of work to implement correctly as you would have to know the procedures Luftwaffe, RAF and others used for their checks. And investing time for research it, code and implement = not worth it in terms of returns it gives. And most users would not use the feature after a few times anyway. So best is to just implement those that are used, not too hard to implement and give immersion to the sim.
Museums..you should visit some plane museums in Finland too, some nice planes to see. I have great interest in the VL Pyörremyrsky (Typhoon) and if it could be done for IL-2, we took pics and such at museum last time visited. 1 was made and it flew 27h and 31 flights. Performance surpassed Bf109G in climb and turn easily, speed was somewhat the same.
I am sure Ville and Raimo did speak about them when meeting you. Boy was I green in face when they showed the pics and told how it was

Maybe some day could haul my son and myself to Moscow, Monino would be great to see and MAKS
