I have been complaining with missing the C172 (G1000) with my
2024 Premium Deluxe purchase.
Turns out that I had it all along.
Check your airplane if certain models are missing.

“In 2024, it seems you have to first pick the plane model (e.g. Cessna 172) and then use Configure to change to a different model of that aircraft. Under 172, I have Cargo, G1000 Aerial Advertising, G1000, Amphibious, Cargo, Skis, Aerial Advertising, G1000 Amphibious, Basic, G1000 Tow, G1000 Skis, Skydiving, and G1000 Skydiving all available to pick.”
