Pressing the CWS Button while Glidepath Mode is active does not cancel the mode.  The autopilot 

guides the aircraft back to the glidepath upon release of the CWS Button.

Glidepath  Mode  is  used  to  track  the  SBAS-based  glidepath.    When  Glidepath  Mode  is  armed,  ‘GP’  is

annunciated in white in the AFCS Status Box.

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).

Ensure that GPS is the selected navigation source (use the CDI Softkey to cycle through navigation sources if 
necessary).

Press the APR Key.

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.

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 (magenta ‘GP’ annunciation):

• The active waypoint is at or after the final approach fix (FAF)

• Vertical deviation is valid

• The CDI is at less than full scale deviation

• Automatic sequencing of waypoints has not been suspended (no ‘SUSP’ annunciation on the HSI)
