GPS APPROACH ALARM LIMITS EXCEEDED

During a GPS LPV, LNAV/VNAV, or LNAV+V approach, if the Horizontal or Vertical alarm limits are exceeded, the
G1000 System will downgrade the approach. This will be annunciated in the ALERTS window and by an
annunciation change on the HSI from LPV, L/VNAV, or LNAV+V to LNAV. GPS glide path vertical guidance will be
removed from the PFD.
The approach may be continued using the LNAV only minimums.
During any GPS approach in which both precision and non-precision alarm 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 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.
