@cptdrinian thanks for pointing this out. we are using point coordinates from the airport centres to calculate distance. I’ll review this number tomorrow, and I’ll have an update asap.
The aim of the points system is to try and correlate the points with value as closely as possible. We still have some work to do, but we’ll correct things quickly when we get it wrong.
Thanks again for the question, and interest in the 4dsky project. 🫡
