My second edition of the Orbx freeware and payware virtual airports, dated May 19 2019 is in the downloadable file below (the link in green). The list is not completed yet.
The information in the PDF file is in colour. The airport in black is part of the global pack freeware. The airport in green is a freeware that is not part of the global pack. The airport in blue is a payware airport.
When a runway is in orange, it means that the length of the runway is 2000 ft or below, and/or the width is 60 ft or below. The water aerodrome are defined by the word “water” in blue. Finally, the elevation of the airport is in red at the end of the runway details.
