QUESTIONUnder § 107.150, a small unmanned aircraft system may be eligible for more than one category of operation over human beings on what condition?

  1. AThe aircraft carries a separate declaration of compliance for each category
  2. BThe aircraft weighs 0.55 pounds or less in every configuration
  3. CThe remote pilot cannot inadvertently switch modes or configurations
Show the answer and explanation

Correct answer: C. The remote pilot cannot inadvertently switch modes or configurations

  • A — incorrect § 107.150 does not require separate declarations; § 107.160(a)(8) even allows a single declaration to cite the means of compliance for Category 2, Category 3, or both.
  • B — incorrect The 0.55-pound limit belongs to Category 1 eligibility under § 107.110(a)(1); it is not the condition stated in § 107.150.
  • C — correct § 107.150 allows eligibility for one or more categories as long as a remote pilot in command cannot inadvertently switch between modes or configurations.

BACKGROUND

Subpart D of 14 CFR part 107 governs operations over human beings and defines Categories 1 through 4. Some aircraft can be configured or switched into different modes that satisfy different categories. § 107.150, titled variable mode and variable configuration of small unmanned aircraft systems, permits a small UAS to be eligible for one or more categories of operation over human beings, as long as a remote pilot in command cannot inadvertently switch between modes or configurations. Related requirements appear in the declaration of compliance rules, which require operating instructions that explain how to verify and change the mode or configuration when it is variable.

STUDY TIP

Remember the single safety condition in § 107.150: no accidental switching between modes or configurations.

KEY POINTS

  • A small UAS may qualify for more than one category over people.
  • The condition is that the remote pilot in command cannot inadvertently switch modes or configurations.
  • Operating instructions must explain how to verify and change a variable mode or configuration.
