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.

Field note →VLOS means you must be able to see the aircraft well enough to determine its orientation, altitude, and flight path without optical aids. In practice, most consumer drones are difficult to orient visually beyond 1,500 feet distance.
