Controlled airspace is a location-and-altitude question
Part 107 requires prior FAA authorization for operations in Class B, C, D, and Class E airspace designated for an airport. Class G is uncontrolled, but it is not hazard-free: traffic patterns, helicopters, agricultural aircraft, emergency aircraft, and local procedures still matter.

| Chart marking | Meaning | Part 107 implication |
|---|---|---|
| Solid blue | Class B | Authorization required |
| Solid magenta | Class C | Authorization required |
| Dashed blue | Class D surface area | Authorization required |
| Dashed magenta | Class E surface area | Authorization required |
| Faded magenta | Class E generally begins at 700 ft AGL | Check planned altitude and local depiction |
| Faded blue | Class E generally begins at 1,200 ft AGL | Check planned altitude and local depiction |
Facility Maps are not permission
A UAS Facility Map grid value is a planning ceiling used in streamlined review. A “100” grid means 100 feet, not an automatic right to fly there. The pilot still needs LAANC or another FAA authorization and must comply with its terms.
Special-use and temporary airspace
- Prohibited areas: operations are prohibited except as provided by the controlling agency.
- Restricted areas: unusual hazards may exist; check active times and controlling agency.
- MOAs: high-speed military activity may occur; status and risk matter even when transit is not automatically prohibited.
- TFRs: time-sensitive restrictions for security, hazards, VIP movement, events, or disaster response.
- NOTAMs: current changes such as closures, hazards, and special activity.
