Which statement best describes Procedural service provided by ATC?

• A. No traffic information is provided
• B. Procedural service, where the ATS provides more detailed traffic information using non-surveillance methods; the pilot remains responsible to stay clear of traffic
• C. Basic service, where ATC provides very basic traffic information
• D. Enhanced radar service with live conflict detection and ATC separation responsibility

Answer: (B)

Procedural service is the method used when ATC provides traffic information and sequencing without radar surveillance. In this mode, controllers rely on non-surveillance means—pilot reports, position data, and clear instructions—to manage traffic, and the responsibility for maintaining separation largely rests with the pilot. That’s why this description fits: ATC gives more detailed traffic information using non-surveillance methods, while the pilot remains responsible to stay clear of others. This differs from radar-based services, where ATC actively monitors traffic on a radar screen and can apply separation or even detect conflicts. The other options don’t fit because no traffic information wouldn’t be provided under procedural service, basic service is a less detailed level of information, and enhanced radar service involves live conflict detection and ATC separation responsibility, which procedural service does not.
