PLT534: sUAS Visual Line of Sight
What code PLT534 covers, why the FAA tests it, and how to study sUAS Visual Line of Sight before your checkride.
Recall regulations - small UAS operational control / condition for safe operation / VLOS / frequency interference
What this means for your checkride
The remote pilot in command must keep the small unmanned aircraft within visual line of sight, with vision unaided except by corrective lenses, so they can see it and the surrounding airspace to avoid other aircraft. The RPIC is responsible for a safe operation, including guarding against control-link or frequency interference.
Visual line of sight is the backbone of Part 107 safety, so the FAA tests the VLOS requirement and the RPIC's control responsibilities.
Operators think a camera feed satisfies VLOS. First-person view does not replace seeing the aircraft; a visual observer can assist, but the operation must maintain visual line of sight as the rule allows.
Where to study it
A code on your test report is an area of deficiency. An authorized instructor must review it with you and endorse that review before you take the practical test, and the examiner may revisit it during the oral. Study it until you can explain it out loud, not just recognize the answer.
