Section 3. EMERGENCY PROCEDURES

3.1

No change.

3.2

3.2.1 LOSS OF GPS/SBAS NAVIGATION DATA

When the GPS/SBAS receiver is inoperative or GPS navigation information is

not available or invalid, the GNS will enter one of two modes: Dead Reckoning

mode (DR) or Loss Of Integrity mode (LOI). The mode is indicated on the GNS

by an amber "DR" or "INTEG".

If the Loss Of Integrity annunciation is displayed, revert to an alternate means of

navigation appropriate to the route and phase of flight.

If the Dead Reckoning annunciation is displayed, the map will continue to be

displayed with an amber ownship icon. Course guidance will be removed on the

CDI. Aircraft position will be based upon the last valid GPS position, then

estimated by Dead Reckoning methods. Changes in true airspeed, altitude,

heading, or winds aloft can affect the estimated position substantially. Dead

Reckoning is only available in Enroute and Oceanic modes. Terminal and

Approach modes do not support Dead Reckoning.

If Alternate Navigation Sources (ILS, LOC, VOR, DME, ADF) Are

Available:

Navigation .......................................................... USE ALTERNATE SOURCES

If No Alternate Navigation Sources Are Available:

DEAD RECKONING (DR) MODE:

Navigation .............................................................................................. USE GNS

All information normally derived from GPS will become less

accurate over time.
