  2. Bany airport, heliport, or seaplane base
  3. Cany airport listed in the Chart Supplement, but not heliports
Show the answer and explanation

Correct answer: B. any airport, heliport, or seaplane base

  • A — incorrect The section is not limited to towered airports. It applies to any airport, and also to heliports and seaplane bases.
  • B — correct § 107.43 states that no person may operate a small unmanned aircraft in a manner that interferes with operations and traffic patterns at any airport, heliport, or seaplane base.
  • C — incorrect Heliports are expressly included, and the section makes no distinction based on whether the airport is listed in the Chart Supplement.

BACKGROUND

Section 107.43 is a short but broad rule: no person may operate a small unmanned aircraft in a manner that interferes with operations and traffic patterns at any airport, heliport, or seaplane base. It applies regardless of whether the airport is towered or non-towered, and regardless of the airspace class. This rule is separate from § 107.41, which requires prior authorization to operate in controlled airspace. A remote pilot can be in compliance with airspace authorization and still violate § 107.43 by interfering with, for example, the traffic pattern at a non-towered field in Class G airspace. The Remote Pilot Study Guide stresses that remote pilots should be familiar with manned aircraft traffic patterns for this reason.

STUDY TIP

Note the three facility types together: airport, heliport, seaplane base. The exam tries to narrow the list to towered or listed airports.

KEY POINTS

  • § 107.43 prohibits interfering with operations and traffic patterns.
  • It covers any airport, heliport, or seaplane base, towered or not.
  • It is independent of the airspace authorization requirement in § 107.41.
