What does VLOS stand for in drone operations?

  1. Very Low Operating Standards

  2. Visual Line of Sight

  3. Variable Launching Operations Strategy

  4. Vertical Lift Operation Systems

The correct answer is: Visual Line of Sight

In drone operations, VLOS stands for Visual Line of Sight. This term refers to the requirement that a drone operator must maintain a visual connection with the drone during flight without the use of artificial aids, such as binoculars or telescopes. Maintaining VLOS is crucial for ensuring safety, as it allows the operator to observe the drone's flight path, avoid obstacles, and assess the drone's positioning in relation to people and property. Visual Line of Sight reinforces the necessity for pilots to interact with their drones in real time, promoting situational awareness and reaction to any potential hazards that may arise during the flight. In this context, VLOS helps to ensure compliance with FAA regulations, as pilots must be able to see the drone at all times to effectively manage its operation.
