Description: VLOS, or Visual Line of Sight, is a term used in drone operation that refers to the requirement for the pilot to keep the drone within their visual line of sight during flight. This means that the operator must be able to see the drone without the aid of optical devices, such as binoculars or augmented reality glasses. VLOS is a fundamental principle in the regulation of unmanned aviation, as it ensures that the pilot can monitor the drone and its surroundings, minimizing the risk of collisions and ensuring more effective control over the aircraft. This requirement is especially relevant in urban environments or in areas with high air traffic density, where visibility and situational awareness are crucial. VLOS also promotes pilot responsibility, as they are expected to be attentive to any obstacles or potential hazards while operating the drone. In summary, Visual Line of Sight is an essential component for safety and effectiveness in drone operation, promoting a safer and more responsible use of this emerging technology.
History: The concept of VLOS was formalized with the rise of unmanned aviation in the 2000s, when drones began to be used not only by military forces but also by civilians. Initial regulations, such as those established by aviation authorities worldwide, required pilots to maintain visual control of the drone to ensure safety in the airspace. As drone technology advanced, new regulations were developed to allow for more complex operations, but VLOS remained a key requirement in many jurisdictions.
Uses: VLOS is primarily used in recreational and commercial drone operations, where the pilot is required to maintain visual control of the drone. This includes applications such as aerial photography, infrastructure inspection, precision agriculture, and surveillance. In various environments, VLOS is crucial to avoid collisions with obstacles, as well as to ensure the safety of people on the ground.
Examples: An example of VLOS use is a photographer operating a drone to capture aerial images of an outdoor event, ensuring that the drone remains within their line of sight at all times. Another case is that of a farmer using a drone to monitor crops, keeping the drone visible while assessing the health of the plants from the air.
