The UTC (Universal Coordinated Time) Nav item is depicted below. For
GPS sensors to initialize properly, the UTC time must be correct.
22:45:03 UTC
The Estimated Time of Arrival (ETA) Nav item is depicted below. ETA is
given in UTC (Universal Time Coordinates) to the current To waypoint. In this
example, ETA to Portland International is 14 hours, 23 minutes, and 3 seconds.
The Estimated Time of Arrival (Destination Waypoint) Nav item appears the
same but displays the destination waypoint identifier and uses the total flight
plan distance remaining to calculate ETA.

The Barometric Altitude Nav item is displayed below. This item shows
pressure altitude corrected for the currently set local altimeter setting. This
altitude should match the altitude displayed on your aircraft altimeter, and it
should also match the altitude displayed next to the currently in use altitude
sensor. In this example, the Barometric Altitude is 1950 feet.
Baro Alt 1950ft
The Time to Descent Nav item is depicted below. This item shows the
time before beginning your descent. This item is used only when auto
descent monitoring is active. If Auto Descent monitoring is not active,
“—:—” is displayed instead of a time. When Auto Descent begins, this
item is replaced by the Glide Path Deviation item, or the Feet Over End
Altitude item. In this example, the time to descent is 1 hour and 9 minutes.
01:09 To Descent
The Glide Path Deviation Nav item is depicted below. This item shows
the distance you are above or below your desired glide path. This item is
displayed only when Auto descent monitoring is active. If the number of
feet above your intended glide path exceeds the number of feet above
your intended end altitude, the Feet Over End Altitude item is displayed
instead. In this example, the distance above the glide path is 50 feet.
50’Above GlPth
The Feet Over End Altitude Nav item is depicted below. This item shows
the distance from your current altitude to your intended auto descent
altitude. It is only shown in the case when the number of feet above your
intended glide path exceeds the number of feet above your intended end
altitude. This scenario may occur when the plane overflies the intended
auto descent destination point without reaching the desired end altitude.
