LC must advise TRACON of all the following except which item?

• A. Weather updates
• B. Aircraft in traffic pattern
• C. Radar status
• D. IFR flight plans

Answer: (B)

Coordinating with TRACON relies on sharing information that helps manage arrivals, departures, and sequencing in the terminal area. Weather updates are shared because changes in weather directly affect approach paths and runway operations, so TRACON needs current conditions to plan clearances and sequencing. Radar status is important because if radar is out or degraded, TRACON must adjust procedures and rely on non-radar methods; the Local Controller must inform them of any radar issues. IFR flight plans are used by TRACON to anticipate inbound traffic and coordinate handoffs; keeping TRACON informed ensures proper sequencing and separation. Aircraft in the traffic pattern, however, stays within the Local Controller’s purview; pattern traffic is managed locally and only reported to TRACON if it transitions into the terminal area or becomes an inbound aircraft. Therefore, the item that does not need to be advised to TRACON is aircraft in the traffic pattern.
