Hi @SugarDog43,
Well thats a lot of experience there! I hope you will enjoy the sim as much as your flying back in the days.
There are a lot of tutorials on youtube that will bring you a massive amount of info about the G1000.
If you have any specific questions, feel free to check the forum or make a topic yourself.
Have fun building your cockpit and if you like you can post the final result in - Post Your Cockpit Pictures Here - - Self-Service / Home Cockpit Builders - Microsoft Flight Simulator Forums
Take care andmaybe we will see eachother soon in MSFS
