QUESTIONA remote pilot plans a survey flight at 300 feet AGL over farmland that lies entirely within Class G airspace. What ATC authorization does part 107 require for this flight?

  1. AAuthorization from the ATC facility that controls the overlying Class E airspace
  2. BNone; ATC authorization is not required in Class G airspace
  3. CA written airspace authorization that is filed at least 24 hours before the flight
Show the answer and explanation

Correct answer: B. None; ATC authorization is not required in Class G airspace

  • A — incorrect The flight stays within Class G, which extends from the surface to the base of the overlying Class E; the overlying airspace is not entered, so no authorization is triggered.
  • B — correct The study guide states plainly that a remote pilot will not need ATC authorization to operate in Class G airspace, and § 107.41 does not list Class G.
  • C — incorrect No advance-filing time period exists in part 107 for Class G operations; the airspace simply does not require ATC authorization.

BACKGROUND

Class G airspace is uncontrolled airspace: the portion not designated as Class A, B, C, D, or E. It extends from the surface up to the base of the overlying Class E airspace. Section 107.41 requires prior Air Traffic Control (ATC) authorization only in Class B, Class C, Class D, and the surface area of Class E designated for an airport. The Remote Pilot Study Guide therefore states that a remote pilot will not need ATC authorization to operate in Class G airspace. Other part 107 limits, such as the 400-foot AGL altitude limit in § 107.51, still apply in Class G.

STUDY TIP

When a scenario places the whole flight in Class G, the airspace-authorization answer is always none; look instead for other operating limits that still apply.

KEY POINTS

  • Class G is uncontrolled airspace from the surface to the base of the overlying Class E.
  • A remote pilot needs no ATC authorization to operate in Class G.
  • § 107.41 lists only Class B, C, D, and surface-area Class E.
