What does VLOS stand for in RPAS operations?

• A. Visual Low Altitude Surveillance
• B. Visual Line-of-Sight
• C. Visual Lateral Offset System
• D. Very Light Optical Sensor

Answer: (B)

VLOS stands for Visual Line-of-Sight. The idea here is that the remote pilot must maintain direct, unaided visual contact with the RPAS throughout the flight, using their own eyes to judge distance, monitor the drone’s path, and spot hazards or airspace restrictions in real time. This allows immediate, on-the-spot decisions to keep the operation safe and compliant. The other options describe concepts that aren’t about how the aircraft is observed (low-altitude surveillance, an unrelated system, or a sensor) and therefore don’t fit the term VLOS.
