3.2.2 GPS APPROACH DOWNGRADE
During a GPS LPV, LNAV/VNAV, or LNAV+V approach, if GPS accuracy
requirements cannot be met by the GPS receiver, the GTN will downgrade the
approach. The downgrade will remove vertical deviation indication from the VDI
and change the approach annunciation accordingly from LPV, L/VNAV, or
LNAV+V to LNAV. The approach may be continued using the LNAV only
minimums.
During a GPS approach in which GPS accuracy requirements cannot be met by
the GPS receiver for any GPS approach type, the GTN will flag all CDI guidance
and display a system message "ABORT APPROACH-GPS approach no longer
available". 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 GTN. Certain failures of the
tuning system will automatically tune 121.5 without pilot action.
3.2.4 LOSS OF AUDIO PANEL FUNCTIONS (GMA 35 Only)
Audio Panel Circuit Breaker ........................................................................ PULL
This procedure will force the audio panel to provide the pilot only with
communications on the Non-GTN 750 radio. If only a GTN 750 is installed in the
aircraft, then the pilot will have communications on the GTN 750. The crew and
passenger intercom will not function.

Sink)
