When replying with 'traffic observed', you should include what information if the traffic call sign is known?

• A. The call sign of the observed traffic.
• B. Your own unit call sign and position only.
• C. The altitude of the observed traffic.
• D. The weather observation of the airspace.

Answer: (A)

The essential point here is to identify the target aircraft when you report traffic observed. If you know the traffic’s call sign, you should include that call sign in your transmission. Providing the exact call sign makes the report unambiguous for ATC, so they can immediately correlate your sighting with the proper aircraft in their surveillance data and take appropriate action to maintain safe separation. Your own unit call sign and position are still part of the transmission, but they don’t identify which aircraft you’ve seen. Weather details aren’t used to identify the aircraft, and altitude alone doesn’t specify which aircraft you’re referencing. Including the call sign is what removes any ambiguity about which traffic you’ve observed.
