When an ILS approach is flown, the ground--based signals must be
used for primary approach guidance. The GPS may be used to
monitor the approach. Advisory vertical guidance is provided.
Auto--tune and auto--switching of the localizer is available when
configured. When not configured for auto--switching, a prompt to
remind the flight crew to switch to VLOC is not provided.
ADVISORY VERTICAL GUIDANCE
Advisory vertical guidance is displayed when permitted by the selected
approach and as long as sufficient health and integrity exists within the
GPS. Advisory vertical guidance is indicated for some approaches by
a +V appended to the approach annunciation in the approach mode
guidance field. If the vertical integrity degrades, the vertical deviations
are flagged invalid.
NOTE: Table 15--2 lists each type of approach supported and if
vertical deviations are provided for each approach.
CAUTION
ADVISORY VERTICAL GUIDANCE DEVIATION INFORMATION
IS ONLY AN AID TO HELP PILOTS COMPLY WITH ALTITUDE
RESTRICTIONS. WHEN USING ADVISORY VERTICAL
GUIDANCE, THE PILOT MUST USE THE PRIMARY
BAROMETRIC ALTIMETER TO ENSURE COMPLIANCE WITH
ALL ALTITUDE RESTRICTIONS, PARTICULARLY DURING
INSTRUMENT APPROACH OPERATIONS. ADVISORY
VERTICAL GUIDANCE IS REMOVED AT THE MISSED
APPROACH POINT.
Uncertified, but FAA--sanctioned, advisory vertical guidance is
generally provided by a published vertical descent angle. Sometimes
the glide path is computed as a geometric path between two waypoints.
These approaches are non--precision and the minimums identified on
the approach as minimum descent altitude (MDA). Minimums may be
reached prior to the missed approach point. The advisory glide path
may not meet every intermediate altitude crossing restriction. The pilot
in command is responsible to meet all altitude crossing restrictions.
