FAA Part 107 Remote Pilot (UAG)Airspace and Operating RequirementsMedium
A remote pilot uses LAANC and finds that the UAS Facility Map grid value at the planned takeoff point in Class D airspace is 100 feet. What does this value represent?
- AThe floor of the overlying Class A airspace
- BThe maximum altitude the FAA will automatically authorize via LAANC at that location
- CThe minimum altitude required to remain clear of clouds
- DThe mandatory cruising altitude for all sUAS in that grid square
Show answer & explanationAnswer & explanation
Correct answer: B. The maximum altitude the FAA will automatically authorize via LAANC at that location
UAS Facility Maps display grid values that represent the maximum altitude the FAA has pre-approved for automatic LAANC authorization at that specific location; a 100-foot grid value means LAANC can instantly approve operations up to 100 feet AGL there.
Why the other options are wrong
- A. Class A begins at 18,000 feet MSL and is unrelated to facility map grids.
- C. Cloud clearance is governed by 107.51, not facility map values.
- D. The grid value is a ceiling, not a required cruising altitude.
UAS Facility Maps
Charts showing the maximum altitude the FAA will automatically authorize sUAS operations via LAANC in specific grid areas of controlled airspace.
- Grid values are ceilings, not floors
- Requests above the grid value require manual FAA review
- Values vary by location based on manned aircraft traffic patterns
Memory trick: Grid number = the ceiling LAANC lets you fly under instantly.
