Which aircraft must be posted to the SPA?

The correct choice indicates that all arrivals from the specified airports—KGWO, KVKS, 0M8, and KTVR—must be posted to the Special Procedures Area (SPA). This requirement is rooted in the need for enhanced management of traffic arriving from these specific locations, which may involve unique operational considerations or protocols that differ from general traffic. By posting these arrivals to the SPA, air traffic control can ensure that these aircraft are monitored and managed appropriately, thereby promoting safety and efficiency within the airspace.

This choice emphasizes the importance of maintaining situational awareness and ensuring that particular flight operations receive the necessary attention and handling as they approach their destinations. The directive supports coordinated efforts among controllers and helps ensure compliance with established procedures designed for those specific arrival points.
