QUESTIONA remote pilot plans to fly a small unmanned aircraft at 200 feet above ground level inside the Class B airspace surrounding one of the nation's busiest airports. What must the remote pilot do before the flight?

  1. ANotify the airport manager at least 24 hours before the flight
  2. BNothing; authorization is needed only above 400 feet AGL
  3. CObtain authorization from ATC
Show the answer and explanation

Correct answer: C. Obtain authorization from ATC

  • A — incorrect Neither part 107 nor the study guide requires advance notice to an airport manager; the requirement is ATC authorization.
  • B — incorrect The authorization requirement applies to operating in Class B airspace at any altitude; the 400-foot figure is a separate altitude limit and does not remove the airspace requirement.
  • C — correct The study guide states that a remote pilot must receive authorization from ATC before operating in Class B airspace, and § 107.41 prohibits operation in Class B without prior ATC authorization.

BACKGROUND

Class B airspace generally extends from the surface to 10,000 feet mean sea level (MSL) around the nation's busiest airports. Because the surface area of Class B starts at the ground, even a low flight near such an airport can be inside controlled airspace. Under 14 CFR § 107.41, no person may operate a small unmanned aircraft in Class B, Class C, or Class D airspace without prior authorization from Air Traffic Control (ATC). The study guide repeats that a remote pilot must receive ATC authorization before operating in Class B.

STUDY TIP

Whenever a planned flight is within Class B, C, or D airspace, treat ATC authorization as a prerequisite regardless of how low you plan to fly.

KEY POINTS

  • Class B airspace starts at the surface around the busiest airports.
  • § 107.41 requires prior ATC authorization for Class B, C and D.
  • Flying low does not remove the authorization requirement.
