What is VLOS?

Visual Line of Sight (VLOS) involves piloting a drone while keeping it within direct, unaided sight. This contrasts with Beyond Visual Line of Sight (BVLOS), where the drone operates beyond the pilot's visual range, often relying on technology for navigation. Extended Visual Line of Sight (EVLOS) is a middle ground, where the drone flies outside the pilot's direct view but within an observer's sight, who communicates with the pilot.
