annunciation, GPS1, GPS2, or RSM GPS, is shown in the lower left corner of the

4.4.6. Ground Track Marker

When configured with a GPS that provides ground track data, a Ground Track Marker is
displayed on the compass scale to indicate the aircraft' s ground track. This marker may be
used to compensate for wind drift during flight (Figures 4-100 and 4-101). The Ground
Track Marker is removed from the display when ground track is not available or invalid.
