11.4 STORMSCOPE OPERATION WITH
LOSS OF HEADING INPUT
If heading is lost, strikes and/or cells must be cleared
manually after the execution of each turn. This is to
ensure that the strike and/or cell positions are depicted
accurately in relation to the nose of the aircraft.
11.5 HAZARD DISPLAYS WITH LOSS OF
GPS POSITION
If GPS position is lost, or becomes invalid, selected
hazards being displayed on the Navigation Map Page
will be removed until GPS position is again established.
The icons in the lower right of the screen, indicating the
selected functions for display, will show an ‘X’, as shown
in Figure 11-3.

11.6 DEAD RECKONING
While in Enroute or Oceanic phase of flight, if the
G1000 detects an invalid GPS solution or is unable to
calculate a GPS position, the system will automatically
revert to Dead Reckoning (DR) Mode. In DR Mode,
the G1000 uses its last-known position combined with
continuously updated airspeed and heading data (when
available) to calculate and display the aircraft’s current
estimated position.
NOTE: Dead Reckoning Mode will only function in
Enroute (ENR) or Oceanic (OCN) phase of flight.
In all other phases, an invalid GPS solution will
produce a “NO GPS POSITION” annunciation on
the map and the G1000 will stop navigating in
GPS Mode.
