Visitng other airports on your flight gives you the opportunity to practice touch and go's. Sometimes I'll land at one of these airports to soak up the local colour and have a cuppa. Also, if the weather closes in or you have an in-flight emergency it's good to have alternate landings available.
Comparing the standard MSFS 2020 scenery with the enhanced scenery offered in this package. You can see the startling transformation. The airport is very frame-rate friendly, I noticed no discernable difference.
With most of the world's 42,000 airports being modelled in Microsoft Flight Simulator you can see the potential. But where to start? To help you out I have created flights out of and around many of the International Airports and also a good number of flights which either take off from or fly over Bush Strips.
