What is required for Visual Line-of-Sight (VLOS) operation of a small UA?

For Visual Line-of-Sight (VLOS) operation of a small Unmanned Aircraft (UA), the operator must be able to see the UA without any aids. This requirement is in place to ensure that the remote pilot maintains situational awareness and can effectively control the aircraft while it is in operation. Being able to see the UA directly allows the operator to make immediate and informed decisions regarding the aircraft's flight path, altitude, and potential obstacles in the environment.

The purpose of VLOS is to enhance safety by requiring that pilots have a clear and unobstructed view of their UA at all times. Without this direct visibility, there is an increased risk of collisions and accidents, as the operator would not have the necessary information to navigate the airspace safely. Thus, maintaining VLOS is a fundamental requirement for compliant and safe operation of small unmanned aircraft systems under FAA regulations.
