Are Beyond Visual Line of Sight (BVLOS) and Beyond Line of Sight (BLOS) the same?

Beyond Visual Line of Sight (BVLOS) and Beyond Line of Sight (BLOS) are not the same and have distinct meanings which is why the correct answer is B.

BVLOS refers to a specific operation where the pilot or remote operator cannot see the aircraft with their eyes, typically requiring special regulatory approvals and procedures for safety, including the use of technology such as drones equipped with detect-and-avoid capabilities or other safety systems. This term is widely recognized in the context of UAS operations and regulations, particularly in the United States.

On the other hand, BLOS is a broader term that encompasses any operation in which the control or observation of the aircraft is outside the visual range without necessarily involving the same regulatory framework as BVLOS. BLOS can be used in a variety of contexts and may not always imply the oversight or regulatory standards characteristic of BVLOS operations.

This distinction is crucial for understanding the requirements and safety implications of different UAS operations, especially in regulatory environments that may treat them differently.
