Several air-to-air modes are used. The Velocity Search Mode is used for maximum-distance encounters, sacrificing detail for range. This provides velocity and azimuth information only. In this mode, targets can be detected at ranges up to 92 miles (150 km). The software controlling the radar is programmed to pay attention to those contacts with positive closure. In the Range-While-Search Mode, the radar provides information on all contacts occuping the portion of the sky ahead of the Hornet at maximum ranges between 40 and 80 nm.

Matched to the AIM-7 Sparrow AAM, Track-While-Scan Mode (TWS) is employed for ranges up to 46 miles (74 km). In TWS mode, the system can track up to ten targets simultaneously and will display the eight deemed most threatening. The computer also presents additional data, typically that of aspect, altitude and velocity.
