Which vision aid may be used to keep a Part 107 drone in visual line of sight?

Corrective lenses only, like glasses or contacts.

  1. Binoculars
  2. Prescription glasses or contacts ✔
  3. A first-person-view (FPV) camera feed

Why: Part 107 requires vision unaided by any device other than corrective lenses. Binoculars and FPV screens do not count for visual line of sight.

Huh, didn't know that: Line of sight can be kept by the remote PIC and the person at the controls, or by a visual observer.

The dad joke
I tried to keep my drone in sight with binoculars. The FAA said that is a bit of a stretch.
