Once a ground target is identified, the Air-to-Surface Ranging Mode provides information on the distance to target. Fixed and Moving Ground Target Track Modes use two-channel monopulse angle tracking to provide precise information on ground targets. The Hornet does not have automatic terrain following capability, but the radar can be used for terrain avoidance, warning the pilot if he is about to fly into anything hard. It is up to the pilot to avoid any collision, with helpful suggestions from the "Bitchin' Betty" aural warning system.
