When installed in an aircraft without a heading source or if Track Up orientation
is selected the maps will be oriented as follows:
Until a valid track is acquired after startup the track defaults to 360.
When groundspeed is less than 5 knots the ownship icon is shown as a
non-directional icon and the map orientation is latched at the last valid
track.
When groundspeed is between 5 and 10 knots, the ownship icon is
shown as a non-directional icon and the map orientation is oriented to
the current track.
When groundspeed is in excess of 10 knots the ownship icon is a
directional icon oriented to track and the map is oriented to track.
The Terrain Page will default to a Heading Up orientation if a heading data
source is installed or will orient to Track Up if no heading data is available.
When oriented to Track Up the Terrain page operation is the same as previously
described. When below 10 knots groundspeed and track up the Terrain Page
cannot be selected to Arc View.
Airspace Depiction and Alerts
The GTN aides the flight crew in avoiding certain airspaces with Smart Airspace
and airspace alerts. Smart Airspace de-emphasizes depicted airspace that is not
near the aircraft's current altitude. Airspace Alerts provide a message indication
to the flight crew when the aircraft's current ground track will intercept an
airspace type that has been selected for alerting.
Smart Airspace and Airspace Alerts are separate features.
Turning on/off Smart Airspace does not affect Airspace
Fuel Planning Page
The Fuel Planning page uses Fuel on Board or Fuel Flow as received from an on
board fuel totalizer, as entered by the pilot at system startup, or as entered by the
pilot when on the Fuel Planning page. This is not a direct indication of actual
aircraft fuel flow or fuel on board and those values are only used for the Fuel
Planning page. The fuel required to destination is only a calculated and
predicted value based on the data entered into the planner. It is not a direct
indication of how much fuel the aircraft will have upon reaching the destination.
Some approach leg types will result in the fuel burn incorrectly calculated as
zero which will be evident when a zero value is shown for the fuel burn for a
leg.
