EASA

The European Union Aviation Safety Agency (EASA) is the central EU authority responsible for civil aviation safety, including drone regulations across EU member states. EASA established harmonized drone regulations for all EU countries through EU Regulation 2019/947 and 2019/945, implementing a risk-based approach with three operation categories: Open, Specific, and Certified. The framework focuses on drone weight, specifications, and intended operations rather than distinguishing between recreational and commercial use.

Notable Facts

Important information about drone regulations

EASA drone regulations apply uniformly across all EU member states, creating a harmonized regulatory environment.
The 'Open' category is for low-risk operations requiring no prior authorization, divided into A1, A2, and A3 subcategories based on operational conditions.
Drone operators must register in their country of residence or principal place of business, with registration recognized throughout the EU.
Different training requirements apply based on operation category, from online training and testing for A1/A3 operations to a theoretical exam and practical self-training for A2 operations.
U-space services will be implemented across the EU to enable complex drone operations, including beyond visual line of sight flights in controlled airspace.
