Cross Track Error Field (XTK)
Cross Track Error Field (XTK) provides a distance
measurement in miles, tenths and hundredths of how far the
aircraft is positioned either right or left of the desired track
(DTK). The maximum value in this field is 9.99 miles.
A positioning symbol, immediately preceding the numerical data, indicates the "fly to" direction required
to null this error.
 If this symbol has its apex to the left (<), the autopilot will fly to the left to eliminate the error.
 If the symbol has its apex the right (>) the autopilot will fly to the right to eliminate the error.
Here the aircraft is just .02 miles to the right of the desired
track, so the autopilot will fly to the left to resume correct DTK.
Other Available Fields on the Bottom Line
The bottom display line, extreme right field is another variable field used to display other tracking data of
interest to the pilot. The possible data fields displayed are:
 GS
Groundspeed, closure speed to the destination waypoint
 ETE
Estimated time en-route, in hours and minutes format
 ETe
Estimated time en-route, in minutes and seconds format
 RNG
Distance from the current “TO” waypoint
 (WPT) "TO" waypoint identifier *
 (TC)
Digital graphic turn coordinator display *
 DIS?
Distance tolerance error indicator
 TRN? Turn tolerance error indicator
 SPD? Speed tolerance error indicator
 TOP
Track Offset Position indicator
 VS
Vertical Speed mode indicator**
 AH
Altitude Hold mode indicator**
* No associated label field displayed
** Shown if the VNAV servo is on
Each field above except the DIS?, TRN? and SPD? fields is selected by pressing the encoder
pushbutton momentarily. The DIS?, TRN? and SPD? fields are automatically displayed to
indicate GPS data anomalies.
The ETE or Ete label format is selected automatically by the autopilot. The TOP field will not be
displayed if the TOP value is 0.00 (no offset).
Groundspeed (GS)
The GS (groundspeed) field indicates the aircraft speed over
the ground in knots as provided by the host GPS system. This
field has a maximum value of 999 knots per hour.
