Which of the following types of operations are excluded from the requirements in part 107? A. Model aircraft for hobby use. B. UAS used for motion picture filming. C. Quadcopter capturing aerial imagery for crop monitoring.

The correct answer is A. Model aircraft for hobby use.<br /><br />Part 107 of the Federal Aviation Administration (FAA) regulations in the United States governs the operation of small unmanned aircraft systems (UAS) for commercial purposes. This includes rules for UAS used for motion picture filming (Option B) and quadcopters capturing aerial imagery for crop monitoring (Option C). However, model aircraft for hobby use (Option A) are generally excluded from these requirements as they are considered to be operated for recreational purposes rather than commercial.
