DUAL GPS/SBAS FAILURE (AMBER “DR” OR “LOI” ON HSI)
LOSS OF GPS/SBAS NAVIGATION DATA
When both GPS/SBAS receivers are inoperative or GPS navigation information is not available or
invalid, the G1000 system will enter one of two modes: Dead Reckoning mode (DR) or Loss Of
Integrity mode (LOI). The mode is indicated on the HSI by an amber “DR” or “LOI”. Which mode is
active depends on the distance from the destination airport in the active flight plan.
In addition, ESP (if installed) will function in a degraded mode. ESP Angle of Attack (AOA) mode
will be inoperative and the following ALERT message will be displayed on both PFDs: “ESP
DEGRADE – ESP AOA mode is inoperative.”
If the LOI annunciation is displayed, revert to an alternate means of navigation appropriate to the
route and phase of flight. In Dead Reckoning mode, the MAP – NAVIGATION MAP will continue to
be displayed with a ghosted aircraft icon in the center and an amber ‘DR’ overwriting the icon.
Aircraft position will be based upon the last valid GPS position, then estimated by Dead Reckoning
methods. Changes in true airspeed, altitude, or winds aloft can affect the estimated position
substantially. Dead Reckoning is only available in Enroute mode; Terminal and Approach modes
do not support DR. Course deviation information will be displayed as an amber CDI on both
PFDs and will remain for up to 20 minutes after GPS position data has been lost. The autopilot
and/or flight director may be coupled in GPS mode while the system is in Dead Reckoning mode.
Refer to the G1000 Cockpit Reference Guide for further information. Revert to an alternate
means of navigation appropriate to the route and phase of flight.
If Alternate Navigation Sources (ILS, LOC, VOR, DME, ADF) Are Available:
1. Navigation ............................................................................. USE ALTERNATE SOURCES
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.
