GPS APPROACH INTEGRITY LIMITS EXCEEDED
During a GPS LP, LPV, LNAV/VNAV, or LNAV+V approach using SBAS, if the Horizontal or
Vertical integrity limits are exceeded, the G1000 System will downgrade the approach. This will
be annunciated in the ALERTS window and may also be accompanied by a change in the
indicated approach type on the HSI. GPS glide path vertical guidance will be removed from the
PFD unless the minimum can still be supported using Baro VNAV. The approach may be
continued as annunciated.
During any GPS approach in which both precision and non-precision integrity limits are
exceeded, the G1000 System will flag the lateral guidance and display a system message
“ABORT APPROACH loss of navigation”. Immediately upon viewing the message, the unit will
revert to Terminal navigation mode integrity 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.
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 Overridden 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
