I would like to suggest Hannover Airport (EDDV / HAJ) in Germany as a future airport for Airport Control 27. I think Hannover would be a particularly interesting addition because it offers several different ATC challenges within one airport: Two parallel main runways: RWY 09L/27R (3,200 m) and RWY 09R/27L (2,340 m). The two main runways form a dependent parallel runway system, creating interesting possibilities for arrival and departure sequencing. A third runway, 09C/27C, is available for VFR traffic and aircraft up to 5.7 tonnes. This would provide a different type of traffic compared with the two main runways. Complex Ground operations with multiple taxiways, aprons and aircraft stands would make pushback and taxi routing interesting. Hannover has a mix of scheduled passenger traffic, charter traffic and significant cargo operations, providing a good variety of aircraft and flight patterns. The airport operates 24/7, making nighttime cargo traffic and different traffic patterns possible. Its traffic volume is substantial enough to provide challenging ATC gameplay without being on the extreme scale of airports such as JFK. Hannover is also an interesting European location that would add Germany and Central Europe to the airport selection. I think EDDV would work especially well for Airport Control 27 because it could offer a good balance between Tower and Ground gameplay, with enough runway and taxiway complexity to create challenging situations without becoming overwhelming. I would be very happy to see Hannover Airport added to the game in the future!
