Flight Test Operations Under Part 108

---

Flight test operations (manufacturer testing, research and development, and experimental flights) receive specific recognition under Part 108. These operations are generally authorized through operating permits with flexibility for larger and heavier aircraft in controlled, low-risk environments.

• Authorization Pathway: Operating Permit (flight test category)
• Maximum Takeoff Weight: Up to 1,320 pounds (including attached items)
• Population Density Categories: Primarily Category 1 (lowest density); very limited in higher categories
• Fleet / Scale Limits: More flexible for manufacturers conducting multiple test programs (exceptions to standard one-permit limits)
• Additional Requirements: Test plans, safety management practices, coordination with FAA as needed, and appropriate risk mitigations for experimental aircraft

Manufacturers, researchers, and developers gain a dedicated pathway for BVLOS flight testing without needing individual exemptions for each test campaign. Operators with disciplined test programs and strong documentation practices will benefit most from this structure.
