I downloaded the Trainer for the Garmin GNS 620 here.
I installed and now have a few programs. I can open the GNS 620, the touchscreen GPS and boot it up, plan a route and so on.
There's also a program to open the G600, the PFD and MFD. However, when I open this program, it just says it can't connect to a simulator and exits.
My questions is: How can I use those trainers properly? How can I simulate the flight? How do I control the virtual plane? Do I need a simulator for this?
I would really appreciate answers, as I have no idea what to do.
