GLIDEPATH MODE (GP) (WITH EXTERNAL WAAS ENABLED
IFR NAVIGATOR ONLY)
Glidepath Mode is used to track a WAAS or other satellite-based augmentation
system SBAS generated glidepath. When Glidepath Mode is armed, ‘GP’ is annunciated
in white in the Autopilot Status Box.
Selecting Glidepath Mode:
1)
EXTERNAL NAVIGATOR: Ensure a GPS approach with vertical guidance
(LPV, LNAV/VNAV, LNAV +V) is loaded into the active flight plan. The active
waypoint must be part of the flight plan (cannot be a direct-to a waypoint
not in the flight plan).
2)
Ensure that GPS is the selected navigation source (use the
CDI
SRC
Softkey
to cycle through navigation sources if necessary).
3)
Press the
APR
Key (GMC 305) or Press the
ALT/PTCH
Softkey to access the
autopilot pitch modes and press the
AP APPR
Softkey (only available when
an external GPS navigation source (i.e., GTN or GNS Series) is configured).
NOTE:
Some RNAV (GPS) approaches provide a vertical descent angle as an
aid in flying a stabilized approach. These approaches are NOT considered
Approaches with Vertical Guidance (APV). Approaches that are annunciated
on the HSI as LNAV or LNAV+V are considered Nonprecision Approaches (NPA)
and are flown to an MDA even though vertical glidepath (GP) information
may be provided.
WARNING:
When flying an LNAV approach (with vertical descent angle) with
the autopilot coupled, the aircraft will not level off at the MDA even if the
MDA is set in the altitude preselect.
Upon reaching the glidepath, the flight director transitions to Glidepath Mode and
begins to capture and track the glidepath.
Once the following conditions have been met, the glidepath can be captured:
• The active waypoint is at or after the final approach fix (FAF).
• Vertical deviation is valid.
