LC must advise TRACON of all the following except which?

• A. Weather updates
• B. Aircraft in traffic pattern
• C. Runway closures
• D. Departures and arrivals

Answer: (B)

The key idea is what information must be shared between the local controller and TRACON to keep arrivals, departures, and overall terminal airspace flow safe and efficient. Weather updates are essential because variable conditions can change approach paths, required separations, and which runway is in use, so TRACON needs to know to adjust clearances and sequencing. Runway closures directly affect available approaches and departures, so informing TRACON helps coordinate alternate routes and handoffs. Departures and arrivals are the core traffic that TRACON manages in the terminal area; keeping them informed ensures proper sequencing and safe transitions between tower and approach/departure control. Aircraft in the traffic pattern, however, are under the local controller’s direct control and typically do not require ongoing advisories to TRACON unless they are about to enter the terminal area or impact its operations. Therefore, the item not required to be relayed is aircraft in the traffic pattern.
