## ATS airspace classes and U-space – services provided

The purpose of this Appendix is to show the services related to [U-space airspace](https://avioverse.aero/glossary/easa/u-space-airspace) provided in each specific airspace class in a concise manner. Therefore, it does not provide any specifications additional to those already expressed in this Regulation and Implementing Regulation (EU) 2021/666 amending Regulation (EU) No 923/2012. Air traffic services provided by ATS units and requirements for IFR and VFR flights remain those expressed in Regulation (EU) No 923/2012 and summarised in its Appendix 4.
