It's not Europe I know, but this link will send you to the PDF file for the Transport Canada AIM. Look in the RAC (Rules of the Air) section. The specific sections you will want to review are RAC 7.9, 8.9, 9.4, 9.12, and 9.13.
Operation into and out of uncontrolled airports is a regular occurence for commercial operators here in Canada, specifically in the northern regions. It is just as safe as operating into controlled airports when everyone follows the rules and procedures outlined in the AIM.
Hope this helps!
