What does the Visual Line of Sight requirement require observers to determine?

• A. The aircraft's speed
• B. The aircraft's color
• C. The system's location, attitude, altitude, and direction of flight with an unaided eye
• D. The aircraft's engine type

Answer: (C)

Visual Line of Sight means the observer must be able to see the unmanned aircraft with the naked eye at all times and determine its position and flight characteristics from that view. From an unaided view, they identify where the aircraft is in the sky (location), how it’s oriented (attitude), how high it is above the ground (altitude), and which way it is moving (direction of flight or heading). This keeps the operator aware of the aircraft’s path and helps maintain safe separation from obstacles and other aircraft. Speeds, colors, or engine type aren’t part of what the Visual Line of Sight requirement requires observers to determine with the naked eye.
