How do pilots receive radar advisories when simultaneous approaches are in progress?

Pilots receive radar advisories during simultaneous approaches primarily on the tower frequency. When multiple aircraft are approaching for landing at the same time, the control tower is responsible for providing separation and guidance to ensure safe landings. Communication through the tower frequency allows for direct coordination between the pilots and air traffic controllers, enabling the controllers to use radar to give timely advisories about their positions and any necessary instructions for safe landing.

The operational frequency, approach frequency, and ground frequency serve different purposes. The operational frequency typically covers a broader range of communications which might not be as targeted as the tower frequency. The approach frequency is generally used for transition into the final approach segment and may not be the primary means for radar advisories if the tower is controlling simultaneous landings. Likewise, the ground frequency is designated for taxiing and is not used during the crucial phase of landing or providing radar advisories. Thus, using the tower frequency is the most effective means for ensuring accurate and safe communication during simultaneous approaches.
