2.7 POSITION PAGE
The Position Page displays the present position (by
default, in latitude and longitude) and altitude. The
Position Page (Figure 2-39) also displays the current
track, ground speed, time, and a reference waypoint field.
These fields are user-selectable to configure the page to
the pilot’s own preferences and current navigation needs.

The graphic track indicator at the top of the page
indicates the direction the aircraft is heading, or track, only
while moving. The graphic track indicator and the TRK
indication directly below it provide the same information.
Use the graphic track indicator for quick at-a-glance
ground track information. Directly below are three user-
selectable fields, which by default display track, ground
speed, and altitude. Barometric pressure (BARO) settings
and minimum safe altitude (MSA) can also be displayed in
these fields. MSA is the recommended minimum altitude
within approximately ten miles of the present position.
MSA is calculated from the information contained in the
database and generally takes into account mountains,
buildings, and other permanent features.
NOTE: Do not rely solely on MSA as an absolute
measure of safe altitude. Consult current area
charts and NOTAMs.
