What is an example of a "non-radar environment"?

A "non-radar environment" refers specifically to airspace where no radar services are available, which means air traffic control cannot track aircraft using radar technology. This scenario is typical in certain remote or less-trafficked areas, where radar coverage might not be feasible due to limited resources or geography.

In a non-radar environment, ATC relies on alternative methods for aircraft separation and communication, such as visual references or position reports from pilots. This makes it distinct from environments where active radar monitoring is utilized, as seen in other controlled airspaces. Understanding this distinction is crucial for pilots and air traffic controllers, as it affects how they interact, the required procedures, and the overall management of air traffic in those areas.
