Flight model modification version 1.14.5.0:

MSFS 2020 has seven AI airplanes that you can not fly. Therefore I made a flight model mod to "unlock" the asobo-aircraft-generic-turbo-singleengine. By fat chance, this airplane looks like a Pilatus PC-12. I admire the love to detail of the Asobo people. Normally you look into the cockpit of an AI airplane, not out of it. What a fine 3D model job they did for something nobody sees normally!

The cockpit has no instruments. Sorry!

Engines don't work? A little tip: Move airplane up in the air with Y. Let airplane fly for some seconds in the air. You should have thrust. Move airplane down to ground with Y. Now engine should work for take-off again.
