Aerosoft announced development of Cologne (Köln/Bonn) Airport back in October 2017. Since then, we have been teased with numerous previews and information regarding the product. Whilst there is a lot of anticipation for the airport, Jo Erlend recently previewed some new screenshots of the airport in the sim.
Whilst still work in progress, Jo did confirm that helipads will be included. Furthermore, although an X-Plane port isn’t currently being worked on, Jo plans to bring one to that Laminar Research sim in the future.
You can find the preview thread on the Aerosoft forums.
