4.5.11 Rate of Turn Indicator
The Rate of Turn Indicator consists of a curved white line originating from the
corresponding side of the aircraft heading (i.e., a left turn indication starts on the left
side of the index mark) and extends in the direction of the turn along the outer radius of
the compass scale (Figure 4-85). The turn rate indication is provided for every compass
mode, 360° and ARC.
The Rate of Turn Indicator features tick marks for full and half-standard rate turns (a
standard rate turn = 3° per second).
The Rate of Turn Indicator has a range of 0° – 6° per second. When the turn rate exceeds
6° per second, an arrowhead is added to the end of the tape to show that the rate of
turn has exceeded the limits of the instrument.
4.5.12 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 4-85 and 4-86).
The Ground Track Marker is removed from the display when ground track data is
not available or invalid.
