While operating under Part 107, remote pilots are required to maintain Visual Line of Sight (VLOS) between the Pilot in Command (PIC) and which of the following?

Under Part 107 regulations, maintaining Visual Line of Sight (VLOS) is fundamental for remote pilots operating unmanned aircraft. The correct choice highlights that VLOS must be maintained between the Pilot in Command (PIC) and the Unmanned Aircraft (UA) during the operation. This requirement ensures that the remote pilot can see the aircraft at all times during flight, allowing for immediate visual evaluation of its surroundings, obstacles, and other air traffic. Keeping the UA in sight assists the pilot in making informed decisions, ensuring safety and compliance with regulations.

By keeping VLOS, the remote pilot can effectively manage the flight, respond to emergencies, and navigate safely. This direct visual contact reduces the risk of collisions and enhances situational awareness in the operating environment, which is critical for maintaining safety in the airspace.
