What is a netted drone enclosure?
A netted drone enclosure is a fully or partially enclosed structure with netted walls and typically a netted ceiling designed to contain drones during operation. It protects people, equipment, and adjacent property and defines controlled airspace for training, research, testing, and racing.
Key design considerations
- Aircraft type (consumer quad, commercial multi-rotor, fixed-wing, hybrid)
- Weight and speed (heavier/faster aircraft need stronger netting + hardware)
- Flight profile (hovering vs. high-speed traversal; ceiling height needs)
- Use case (racing, testing, training, production)
- Indoor vs. outdoor (wind/UV/precipitation and/or fire code constraints)
Material options
HDPE (high-density polyethylene)
Best for: Indoor / light-duty applications
Lightweight, UV-resistant, does not absorb water
UV-stabilized knotted nylon
Best for: Outdoor enclosures and heavier/faster aircraft
Higher tensile strength and superior impact absorption
Kevlar (NFPA 701 options)
Best for: Flame-rated environments and specialty applications
Exceptional tensile strength; used in high-security and indoor arenas where fire code applies
Structural engineering notes
Drone enclosures follow the same structural principles as sports netting: engineered poles, tensioned cables, and supported netting fields. For taller enclosures (often 30+ feet), stamped engineering drawings are commonly required, including wind-load calculations, foundation design, and cable specifications.
Upper support cables are typically specified with at least 3,000 lb bursting strength, and netting fields should be supported approximately every 1,300 square feet to minimize sag and stress concentration.
FAA and local considerations
A fully enclosed netted structure is generally outside FAA Part 107 jurisdiction because it is not outdoor airspace. However, tall structures can still be considered aviation obstructions depending on location and height, and local zoning/building codes always apply.
- Structure height near airports or in busy corridors may trigger obstruction review
- Obstruction lighting (AWL) may be required for tall structures
- Local zoning, setback requirements, and permit processes vary by jurisdiction
FAQ
Do I need FAA approval for a netted drone enclosure?
A fully enclosed netted structure is generally exempt from FAA Part 107 jurisdiction because it is not outdoor airspace. However, tall structures near airports or in busy corridors may qualify as obstructions and require additional review and/or obstruction lighting. Always confirm with an FAA-authorized specialist and local building department.
Can a drone enclosure be built outdoors?
Yes. Outdoor systems require engineered poles, concrete foundations, UV-stabilized netting, and wind-load calculations. Permitting and obstruction lighting may apply.
What netting material is right?
HDPE can work indoors for light-duty. UV-stabilized nylon is preferred outdoors and for heavier aircraft. Kevlar is used where flame rating or high-security requirements apply.
