1.1 This specification applies to unmanned aircraft (UA) with a maximum dimension (for example, wingspan, disc diameter) ≤25 ft, operating at airspeeds below 100 kts, and of any configuration or category. It is meant to be applied in a “lower risk” (low- and medium-risk airspace as described by Joint Authorities for Rulemaking on Unmanned Systems (JARUS)) airspace environment with assumed infrequent encounters with manned aircraft; this is typically in classes G and E airspace (below about 1200 ft above ground level (AGL)), Class B, C, D (below about 400 to 500 ft AGL), below obstacle clearance surface (FAA Order 8260.3, as amended), or within low altitude authorization and notification capability (LAANC) designated areas below the altitude specified in the facility map.
