DTG Flight School is getting ready for release (towards the end of April, if the comment in this video is accurate) and we can start to expect to see more live action previews of the platform. In the video attached here, you can have a quick peek at how it will all look like. The video is about 10 min in length, but you would want to skip to around the 6:45 min mark if you only care to see DTG FS in action.
It does look like the terrain is FTX Global as reported earlier, and from what we can see in the video the sim will offer a lot of guidance on your way to learning how to fly the Pipers.
