ILS DATABASE FREQUENCY AND/OR COURSE MISMATCH
In some rare instances, the actual course and/or frequency for an ILS localizer may not match the
course or frequency stored in the G1000 database. This occurs most often when an ILS course or
frequency change is made by the FAA in between Jeppesen database update cycles. Manual
course or frequency changes can be made to override the auto-loaded values in the G1000 database
whenever an ILS approach is loaded into the G1000 via the FMS. ADVISORY messages will post in
the ALERTS window on the PFDs prompting the pilot verify course and/or frequency information.
Use the latest published instrument approach procedure information to verify all course and
frequency information.
While flying ILS approaches with manually overridden course or frequency information:
• For airplanes with TAWS-A installed, the Glideslope Deviation Alerting (GSD) will be
function normally.
• If SVS Pathways are turned on for display, they must be turned off prior to turning
inbound onto the final approach course to prevent possible confusion. This is because
the pathway display is also dependent on accurate database information to display
proper guidance.
If SVS Pathways are Displayed While Flying a Manually Overriden Frequency or Course on an ILS
Approach:
Prior to Turning Inbound on the Final Approach Course:
1. PFD Softkey on PFD1 and/or PFD2 .................................................................................... PRESS
2. SYN VIS Softkey .................................................................................................................... PRESS
3. PATHWAY Softkey ...................................................... PRESS TO REMOVE PATHWAY DISPLAY
LOSS OF RADIO TUNING FUNCTIONS
1. COM Frequency Toggle Button ........................................... PRESS AND HOLD FOR 2 SECONDS
NOTE
The above procedure will tune the active COM field to the emergency frequency 121.5.
Certain failures of the tuning system will automatically tune 121.5 without pilot action.
If the EMERG FREQ switch is installed, the following alternate procedure may be used:
1. EMERG FREQ switch ............................................................................. LIFT COVER AND PRESS
NOTE
The above procedure will tune the active COM 1 field to the emergency frequency 121.5.
COM 2 operation is not controlled by the EMERG FREQ switch.
