the required Horizontal Alarm Limit (HAL) to ensure the GPS
position integrity is within limits to complete the LP non-
precision approach. In the event the HAL limits are exceeded,
the approach will be downgraded, when available, indicated
by "LNAV" on the moving map, otherwise the approach
will be aborted. A message will note that the approach is
downgraded and the NAV indicator will be flagged until the
message is viewed. You may continue the approach using
LNAV non-precision minimums if there are LNAV minimums
for this approach. In the rare event the GPS HAL limits cannot
meet non-precision limits, the GTN will notify the pilot with
a message to abort the approach. The GTN will revert to
terminal limits of 1.0 NM to support navigation to the missed
approach. If the approach is indicating an LP +V, it is possible
that the advisory vertical guidance could be removed without
annunciation due to the vertical guidance not being within
tolerances. This does not constitute a downgrade, and the
approach can still be flown to LP minimums.
