If No Alternate Navigation Sources Are Available:
DEAD RECKONING (DR) MODE - ACTIVE WHEN THE AIRPLANE IS GREATER THAN 30 NM FROM
THE DESTINATION AIRPORT:
1. Navigation - Use the airplane symbol, magenta course line on the map display and the amber
CDI for course information.
NOTE
• ALL INFORMATION NORMALLY DERIVED FROM GPS TURNS AMBER. ALL OF THIS
INFORMATION WILL BECOME LESS ACCURATE OVER TIME.
• TAWS is inoperative.
• DR mode uses heading, true airspeed, last known wind data, and the last known GPS
position to estimate the airplane’s current position. DR information will be available for a
maximum of 20 minutes.
• MAP – TRAFFIC MAP display is not dependent on GPS information. The position of
displayed traffic relative to the airplane symbol on the map is still accurate.
LOSS OF INTEGRITY (LOI) MODE - ACTIVE WHEN THE AIRPLANE IS WITHIN 30NM OF THE
DESTINATION OR DEPARTURE AIRPORT (AS CALCULATED FROM THE PREVIOUS GPS OR DR
POSITION):
1. Navigation - Fly toward known visual conditions. Use ATC or other information sources as
available.
NOTE
• All information derived from GPS or DR will be removed from the displays.
• TAWS is inoperative.
• The airplane symbol is removed from all maps. The map will remain centered at the last
known position. “NO GPS POSITION” will be annunciated in the center of the map.
GPS APPROACH ALARM LIMITS EXCEEDED
During a GPS LPV, LNAV/VNAV, or LNAV+V approach, if the Horizontal or Vertical alarm limits
are exceeded, the G1000 System will downgrade the approach. This will be annunciated in the
ALERTS window and by an annunciation change on the HSI from LPV, L/VNAV, or LNAV+V to
LNAV. GPS glide path vertical guidance will be removed from the PFD. The approach may be
continued using the LNAV only minimums.
During any GPS approach in which both precision and non-precision alarm limits are exceeded,
the G1000 System will flag the lateral guidance and display a system message “ABORT
APPROACH loss of navigation”. Immediately upon viewing the message, the unit will revert to
Terminal navigation mode alarm limits. If the position integrity is within these limits lateral
guidance will be restored and the GPS may be used to execute the missed approach, otherwise
alternate means of navigation must be utilized.
