Under Part 107, a remote pilot in command must maintain visual line of sight (VLOS) with the small UAS. Which best describes the VLOS requirement?
Why →
Under 14 CFR § 107.31, the remote PIC must maintain VLOS using their own natural vision (corrective lenses permitted). No devices such as binoculars, FPV goggles, or cameras may substitute for direct unaided visual observation. A visual observer may assist, but the remote PIC retains legal VLOS responsibility.The trap →
Binoculars and FPV systems do not satisfy VLOS. They are optical aids that the FAA specifically does not allow for this purpose. A VO assists the PIC but does not replace the PIC's own VLOS duty.SOURCE → 14 CFR § 107.31CHECKED APR 21ACS V.A.K7EASY
