Garmin GNC 420 Pilot's Manual & Reference page 37

Directly below the CDI appears the active leg of your flight plan, or the direct-to
D
destination when using the
your flight plan as you reach each interim waypoint. If no flight plan or direct-to destina-
tion has been selected, the destination field will remain blank.
Selecting Desired On-Screen Data
At the bottom of the default NAV page you'll find six user-definable fields which
display the data you'll need as your flight progresses. By default these fields display:
distance to destination (DIS), desired track (DTK), bearing to destination (BRG), ground
speed (GS), ground track (TRK) and estimated time en route (ETE). However, each of
these fields can be custom-tailored to your preferences by selecting a different data item.
Available data items include:
• Bearing to destination (BRG)
• Distance to destination (DIS)
• En route safe altitude (ESA)
• Estimate time en route (ETE)
• Minimum safe altitude (MSA)
• Ground track (TRK)
• Cross track error (XTK)
If no flight plan or direct-to destination has been selected only speed, track, altitude
and minimum safe altitude data may be displayed. All other data types will appear as
blank lines—on the default NAV page—until a destination is selected.
To select a different data item for any data field:
