Non-radar, procedural separation is applied in environments where radar coverage is limited or absent; which environments are typical?

• A. In oceanic routes and some terminal areas where radar is limited or absent
• B. In all areas with continuous radar
• C. Only at uncontrolled airfields
• D. Only when TCAS is inoperative

Answer: (A)

Non-radar, procedural separation relies on time-based and position-based spacing because radar surveillance isn’t available to monitor aircraft positions in real time. This approach is used where you can’t see aircraft on a radar screen, so controllers and pilots follow fixed procedures to keep them apart. The environments where this is typical are oceanic routes and some terminal areas where radar coverage is limited or absent. In these places, pilots report their position at established intervals, follow published routes and altitudes, and adhere to assigned speeds to maintain safe spacing. When radar coverage is present, radar-based separation is used instead; non-radar methods aren’t tied to conditions like TCAS status or to uncontrolled fields.
