Please remember that not all airports are currently up to date to infinite flight’s standards. This is why we have the infinite flight airport editing team who are hard at work at reworking every airport. By updating the layouts including adding taxiways etc…
It takes time and they hope to have every airport done some time in the future. If you would like to see this airport done (if it is not already currently being reworked) , then you can easily become an editor yourself by visiting their thread here.
