2.5.2 Loss of Heading Input
The source for heading data on your aircraft is dependent upon the
particular complement of equipment you have installed in your
aircraft. Loss of heading is typically associated with the failure of one
of the following:
l
The WX-500 Stormscope system (if installed and a heading
source is connected to the WX-500).
l
The Skywatch system (if installed and a heading source is
connected to the TAS).
l
A problem with heading from a Primary Flight Display (PFD).
l
The GPS (This would be a pass through of the heading from
another source, such as an Avidyne PFD. The GPS does not
determine heading).
If an installed heading source becomes unavailable or invalid, the
EX5000 will automatically switch to using GPS track for map
alignment.
If the track source also becomes unavailable or invalid, the following
conditions will occur:
l
All traffic and lightning data is removed from the display.
l
The aircraft symbol is replaced by a direction-less symbol (a
white + symbol).
l
The compass labels (N,S, E, and W) are removed from the
display.
l
The map and flight plan data will continue to be displayed.
l
The map orientation annunciation is removed from the display.
l
The heading/track indicator will display a series of dashes (“---”).
l
The map is oriented True North Up.
What to do:
l
Have the avionics wiring inspected.
When heading/track is restored, Map will resume normal operations.
