Drones weighing more than 5 kg: everything you need to know about Classes 1a and 1b

In Belgium, drones weighing more than 5 kg fall under the strictest categories: Classes 1a and 1b. These drones are typically used for professional applications such as industrial inspections, film productions, agriculture, emergency response, or large-scale aerial surveys. They offer a great deal of power and advanced features, but they also entail greater responsibility and legal obligations.

Legislation in a Nutshell

Under Belgian drone regulations, drones are classified based on their weight:

  • < 1 kg – Leisure use (recreational)

  • 1–5 kg – Class 2 (semi-professional)

  • > 5 kg – Classes 1a and 1b (professional)

Class 1 drones weigh between 5 kg and 150 kg. Because of their size and power, they are subject to the strictest regulations. Pilots must hold specific licenses, complete training, and comply with additional safety requirements.

Overview of Drone Legislation

Classes 1a and 1b: for professional use

This category is intended exclusively for professional pilots and organizations. Some typical applications include:

  • Professional-Quality Film and Video Productions

  • Inspections of Infrastructure and Industrial Facilities

  • Precision Agriculture and Geospatial Surveys

  • Emergency and Rescue Operations

  • Transportation of equipment or specialized sensors

Because of their weight and capabilities, these drones can carry heavier payloads, fly for longer periods, and complete more complex missions than lighter models.

Additional Requirements and Responsibilities

Using drones in Class 1 requires more than just a permit. You must take the following into account:

  • Pilot Training and Certification

  • Airspace Clearance and Flight Plans

  • Insurance and Liability Coverage

  • Strict safety protocols for staff and the surrounding area

In addition, it is mandatory to register the drone and document all operations.

Conclusion

Drones weighing more than 5 kg are powerful tools for professional applications, but they also come with strict legal requirements. They are not intended for recreational use, but rather for companies and organizations that use drones in their day-to-day operations. With the proper permits, preparation, and knowledge, they are indispensable in countless industries.
