Used for Terrain Following (TF) and Terrain Avoidance (TA), Ground Mapping (GM) and Air-to Ground Ranging (AGR). The TF mode supplies commands which are processed and displayed as climb/dive commands on the Flight Director display and E-squared video used by the operators in anticipating near term TF commands. When in TA or GM modes, the operator is provided with a Plan Position Indicator (PPI) display. The AGR mode allows the operators to determine the range to a designated target, which can be used for position updates.
