QUESTIONUnder § 107.150, a small unmanned aircraft system may be eligible for more than one category of operation over human beings only if the remote pilot in command

  1. Aholds a separate waiver for each declared category
  2. Bcannot inadvertently switch between modes or configurations
  3. Crecords every configuration change in the aircraft maintenance logbook
Show the answer and explanation

Correct answer: B. cannot inadvertently switch between modes or configurations

  • A — incorrect Section 107.150 says nothing about waivers; eligibility for several categories does not depend on holding one.
  • B — correct Section 107.150 permits eligibility for one or more categories as long as a remote pilot in command cannot inadvertently switch between modes or configurations.
  • C — incorrect No logbook entry for configuration changes is required by § 107.150; the rule addresses inadvertent switching.

BACKGROUND

Some small unmanned aircraft systems can be flown in more than one physical configuration, for example with or without an attached component, and each configuration may meet a different category standard for operations over human beings. Section 107.150 allows a system to be eligible for one or more categories under subpart D, as long as a remote pilot in command cannot inadvertently switch between modes or configurations. The concern is that a pilot might unknowingly fly in a configuration that no longer meets the declared category. Related to this, the remote pilot operating instructions required by § 107.120(b)(2) and § 107.130(b)(2) must explain how to verify and change the mode or configuration of the system when those are variable.

STUDY TIP

Tie § 107.150 to the operating instructions: the rule permits multiple configurations, and the instructions tell you how to confirm which one you are in. If a choice adds a waiver or a recordkeeping step, check whether the regulation actually mentions it.

KEY POINTS

  • A small unmanned aircraft system may be eligible for more than one category of operation over human beings.
  • The condition is that the remote pilot in command cannot inadvertently switch between modes or configurations.
  • Remote pilot operating instructions must cover how to verify and change a variable mode or configuration.
