We ask all pilots to also read the [General section](https://knowledgebase.vatsim-germany.org/books/airports-langen-fir-edgg/page/general-KrV "Pilotbriefing EDDK - General") with **information relevant to all pilots**.
Köln/Bonn’s airspace and general traffic levels make the airport **friendly, but occasionally challenging to VFR traffic** in the real world. As this is similar on VATSIM, controllers will usually be able to accommodate VFR requests. However, the limited amount of space and complex runway system at Köln/Bonn can result in situations where some VFR requests might be denied during periods of high traffic.Additionally, you should be prepared for the controller to **instruct you to leave the control zone** if the traffic load rises or you fail to comply with instructions promptly and accurately.
