FAA Part 107 Remote Pilot (UAG)Airspace and Operating RequirementsMedium
A commercial UAS operator wants to fly within the lateral boundaries of Class D airspace surrounding a small airport with an operating control tower. What must the operator do before flying?
- AWait until the tower closes for the day, converting the airspace to Class G
- BNothing, Class D airspace allows unrestricted UAS operations below 400 feet AGL
- CObtain authorization from air traffic control before operating in that airspace
- DFile a NOTAM at least 24 hours in advance instead of contacting ATC
Show answer & explanationAnswer & explanation
Correct answer: C. Obtain authorization from air traffic control before operating in that airspace
Class D airspace is controlled airspace, so under 14 CFR 107.41 a remote pilot must obtain ATC authorization (often via LAANC where available) before operating within it, regardless of altitude.
Why the other options are wrong
- A. Waiting for tower closure changes airspace to Class E/G but is not a required or practical compliance method.
- B. Class D is controlled airspace and does require authorization.
- D. A NOTAM does not substitute for required ATC authorization.
Class D Airspace
Controlled airspace around airports with an operating control tower, typically extending from the surface to 2,500 feet AGL.
- Requires ATC authorization for Part 107 operations
- Depicted with a dashed blue line on sectionals
- Reverts to Class E or G when tower is not in operation
- LAANC may be available for many Class D facilities
