Airspace classes explained for drone pilots

U.S. airspace is divided into classes A through G. For Part 107 the key question is simple: is this controlled airspace that needs authorization, or not? Here's each class, drone-first.

The quick answer (LAANC)

Class B, C, D, and surface Class E are controlled and require ATC authorization — almost always granted in seconds through LAANC. Class G is uncontrolled and needs no authorization. Whatever the class, Part 107 still caps you at 400 ft AGL.

Class B — busiest airports

Class B surrounds the busiest airports (think JFK, LAX, ORD) and is shaped like an upside-down wedding cake. Authorization is required for any Part 107 flight inside it.

Class C — moderate traffic with radar

Class C surrounds airports with an operational control tower, radar approach control, and moderate traffic. Authorization is required.

Class D — towered, no radar approach

Class D surrounds airports with an operational control tower but no radar approach. Authorization is required.

Class E — controlled, but not B/C/D

Class E is controlled airspace that isn't B, C, or D. Most of the sky above 1,200 ft AGL is Class E, but for Part 107 you only need authorization inside surface Class E designated for an airport.

Class G — uncontrolled

Class G is uncontrolled airspace — no ATC authorization required. Most rural drone flights happen here.

Class A — good to know, never flown

Class A is high-altitude IFR airspace from 18,000 ft MSL up to FL600. Part 107 drones never operate there, but the exam expects you to know it exists.
