# Overview Köln/Bonn is a complex airport with crossing runways and very little space on the ground and in the TMA. On VATSIM, it usually has a medium amount of traffic but will regularly operate at or even above capacity during events. **Köln/Bonn is an unrestricted airport.** DEL and GND are unrestricted and can be staffed by all controllers with an S1 rating or higher who have passed the **required moodle courses**. TWR position requires the EDDK\_TWR Tier 1 endorsement which can be acquired by all controllers with an **S2** rating or higher. All radar positions require the EDDK\_APP Tier 1 endorsement which can be acquired by all controllers with an **S3** rating or higher.
Due to the high amount of complexity of the airport, it is highly recommended that **S1-rated controllers** have gained a great deal of experience at other unrestricted airports before staffing positions at Köln/Bonn.
**Training:** Controllers with the S1 rating can staff TWR during their training (active EDDK\_TWR solo endorsement required). Controllers with the S2 rating can staff APP positions during their training (active EDDK\_APP solo endorsement required - sector NOR not included). ### Köln/Bonn ATC Stations**Station** | **Station ID** | **Login** | **Frequency** | **Remarks** | **Endorsement** |
