7.8 StormScope ® (Optional)
When optionally interfaced to a StormScope
®
weather detection system, the
GTN may be used to display the StormScope ® information. Weather
information supplied by the StormScope ® will be displayed on the StormScope ®
page of the GTN system. For detailed information about the capabilities and
limitations of the StormScope
®
system, refer to the documentation provided
with that system.
Heading Up mode:
If the GTN system is receiving valid heading information, the StormScope
®
page will operate in the heading up mode as indicated by the label “HDG UP”
presented at the upper right corner of the display. In this mode, information
provided by the StormScope
®
system is displayed relative to the nose of the
aircraft and is automatically rotated to the correct relative position as the aircraft
turns.
Heading Not Available mode:
If the GTN system is not receiving valid heading information, either because a
compatible heading system is not installed, or the interfaced heading system has
malfunctioned, the StormScope
®
page will continue to operate without a
heading source and indicate “ HDG N/A ” in the upper right corner of the GTN
display. In this mode, information provided by the StormScope
®
system is
displayed relative to the nose of the aircraft but is not automatically rotated to
the correct relative position as the aircraft turns. When operating in this mode,
StormScope
®
strikes must be cleared after each turn the aircraft performs.
