We’re doing a couple of touch-and-go’s along the route, ACARS is probably not going to work for this flight.

In the download there are 2 addon airports, copy them to your community folder.
Even a Cessna 208b is likely too large for these small airstrips.
You’ll need something smaller, like the CubCrafters NXCub.
Preferably get the advanced version (freeware, get the Beta, a really excellent plane!):
