When radar is unavailable, which method best communicates traffic information to pilots?

• A. Rely on pilot reports of traffic density only.
• B. Describe traffic using landmarks and runways relative positions, and provide turn instructions as needed.
• C. Provide only general traffic advisories without precise positioning.
• D. Request additional radar coverage from the supervisor.

Answer: (C)

When radar is not available, you can’t build an accurate, verifiable picture of where other aircraft are. The safest and most effective way to keep pilots informed is to issue general traffic advisories that acknowledge the presence of traffic in the area without stating precise positions. This relies on pilots’ own position reports and their ability to see and hear traffic, reducing the risk of acting on unverified or misleading bearings or distances. You can use broad references when helpful, but the emphasis is on general awareness rather than fixed, exact locations. This approach is preferable because it preserves situational awareness and allows pilots to maintain self-separation when a precise radar-derived traffic picture isn’t available.
