These rules divide the airspace into several classes, each one is defined in terms of the traffic volume allowed to fly in it, depending on the flight rules, aircraft equipage, pilot qualifications and the services rendered (for instance full air navigation services or just flight information to the pilot). The airspace classes cover the airspace from ground level. The Regulation includes a main body and an Annex named ‘’Rules of the Air’’ followed by five Appendices.

The Easy Access Rules for SERA, for easier understanding, are shown in a consolidated, easy-to-read format which includes advanced navigation features through links and bookmarks. Moreover, the different elements of the document have colours assigned as well as different fonts. The document will be regularly updated to include further changes.

It is important to mention that this is a relevant step reached in the development and deployment of the common airspace for manned and unmanned aircrafts. However, there is a lot of work to do in the following years to ensure safe operations and to create an appropriate social awareness.
