Class G airspace — “Uncontrolled.”

• Default airspace from the surface up to 700 or 1 200 ft AGL wherever there is no overlying B/C/D/E designation.
• The FAA provides no ATC services in Class G.
• Drone rule: no ATC authorization needed in Class G, but all other Part 107 rules still apply (400 AGL limit, visibility, cloud clearance, daylight, 100 mph, etc.).
