Question: What is a potential concern when using cellular technologies for remote controlled UAVs beyond visual line-of-sight?
Option 1: Interference with other aircraft systems
Option 2: Exposing public safety and security concerns due to out-of-sight flying
Option 3: Increased risk of UAV collisions with obstacles
Option 4: Reduced UAV navigation accuracy
Explanation: The use of cellular technologies for remote controlled UAVs beyond visual line-of-sight can raise public safety and security concerns, such as the potential for out-of-sight flying or uncontrolled UAV movement. This concern is particularly relevant in countries where there may be restrictions on UAV flight ranges to prevent such incidents.
