QUESTIONUnder § 107.35, for how many unmanned aircraft may one person manipulate the flight controls, or act as remote pilot in command or visual observer, at the same time?

  1. ANo more than two aircraft, if both weigh less than 55 pounds
  2. BNo more than one unmanned aircraft
  3. CAny number, provided all of them remain within visual line of sight
Show the answer and explanation

Correct answer: B. No more than one unmanned aircraft

  • A — incorrect The 55-pound figure is the definition of a small unmanned aircraft, not a condition for operating two at once. § 107.35 permits only one.
  • B — correct § 107.35 states that a person may not manipulate flight controls or act as remote pilot in command or visual observer in the operation of more than one unmanned aircraft at the same time.
  • C — incorrect Maintaining visual line of sight does not lift the restriction. § 107.35 limits each person to one unmanned aircraft at a time.

BACKGROUND

Section 107.35 prohibits a person from manipulating the flight controls, or acting as remote pilot in command (remote PIC) or visual observer, in the operation of more than one unmanned aircraft at the same time. The rule is tied to the person, not to the aircraft's weight or to airspace. It exists because the see-and-avoid and situational-awareness duties in §§ 107.31 and 107.37 depend on each crewmember's full attention on a single aircraft. Operating several aircraft simultaneously requires a waiver, since § 107.35 is listed in § 107.205 as a regulation subject to waiver.

STUDY TIP

The answer is simply one. If a question suggests two or more aircraft per person without a waiver, it is describing a violation.

KEY POINTS

  • One person, one unmanned aircraft at a time, in every crew role.
  • Visual line of sight or light weight does not change the limit.
  • Multiple-aircraft operations require a waiver of § 107.35.
