LOSS OF INTEGRITY (LOI) MODE:

Navigation ...................... FLY TOWARDS KNOWN VISUAL CONDITIONS

All information derived from GPS will be removed.

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.

3.2.2 GPS APPROACH DOWNGRADE

During a GPS LPV, LNAV/VNAV, LP +V, or LNAV+V approach, if GPS

accuracy requirements cannot be met by the GPS receiver prior to the Final

Approach Fix, the GNS will downgrade the approach. The downgrade will

remove vertical deviation indication from the VDI and change the approach

annunciation accordingly from LPV, L/VNAV, LP +V, or LNAV+V to LNAV.

The approach may be continued using the LNAV only minimums. After the

Final Approach Fix has been passed, the approach will be aborted using the

indications described below.

During a GPS approach in which GPS accuracy requirements cannot be met by

the GPS receiver for any GPS approach type, the GNS will flag all CDI 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.

3.2.3 LOSS OF COM RADIO TUNING FUNCTIONS

If alternate COM is available:

Communications ......................................................... USE ALTERNATE COM

If no alternate COM is available:

COM RMT XFR key (if installed) ....... PRESS AND HOLD FOR 2 SECONDS

This procedure will tune the active COM radio the

emergency frequency 121.5, regardless of what frequency is

displayed on the GNS. Certain failures of the tuning system

will automatically tune 121.5 without flight crew action.
