You can do training on Level D simulator just get NOC from DGCA.
As far as I know Pan Am Miami doesnt have G1000 cockpit sim
where as Flight Safety Wichita has one and is very professional regarding the training. I heard there is an academy in Australia
which provides training on real aircraft but neither I am sure whether
they do training on G1000 nor I have the name of academy with me right now but will try to inquire about it.
