What document does it justify that an operator can conduct commercial operations with balloons?

Once the declaration required in BOP.ADD.100 has been submitted, the operator is authorised to conduct commercial operations with balloons in all the States of the European Union.

The Spanish Aviation Safety Agency shall publish and keep up-to-date the list of balloon operators who conduct commercial operations and who have submitted a declaration in Spain.

In duly justified cases and at the request of the operator, a certificate attesting that a declaration for commercial operations with balloons has been submitted to the State Aviation Safety Agency may be issued.
