Under 14 CFR § 107.47, a remote pilot in command operating near an area designated by a NOTAM for disaster/hazard relief, an emergency, or a security concern must comply with which other regulations?
Why: 14 CFR § 107.47 states that a person acting as remote pilot in command must comply with the provisions of §§ 91.137 through 91.145 and § 99.7, which govern flight restrictions in the proximity of certain areas designated by a NOTAM.
14 CFR part 121 governs air carrier operations and has no bearing on § 107.47's NOTAM-area restrictions.
§ 61.56 covers flight review currency for part 61 pilot certificate holders; it is unrelated to the NOTAM-area restrictions § 107.47 cross-references.
