What is Uncontrolled airspace (Class G)?
Uncontrolled airspace is airspace where ATC doesn't provide separation services — Class G in the FAA classification. Drone flight in Class G doesn't require LAANC, only standard operating rules.
Class G is the only uncontrolled airspace class. It's the layer below the lowest controlled-airspace floor — typically up to 700 ft AGL where Class E begins above, or up to 1,200 ft AGL in remote areas.
Drone flight in Class G doesn't require LAANC. All other rules still apply: 400 ft AGL limit, VLOS, daylight, registration, Remote ID, TFR avoidance, operating limits.
Much of rural America is Class G to at least 700 ft AGL. Once outside the 30-mile mode-C ring of major airports and away from federal airways, Class G is usually the floor airspace.
What this means for pilots
Class G is the most permissive airspace for drones. Verify you're actually in Class G before flying without LAANC — non-towered airports with instrument approaches create Class E surface areas that look like Class G on casual inspection but legally aren't.
FAQ
Can I fly anywhere in Class G?
Subject to all other rules — 400 ft AGL, VLOS, TFR avoidance — yes.
How do I know if my location is Class G?
Sectional chart or airspace tool. Lack of any controlled-airspace marking means Class G.
Is Class G the same as 'uncontrolled airspace'?
Yes. The terms are synonymous in US airspace.
