Precision Approaches
The Entegra
PFD is designed to take full advantage of the auto transition capability of the
GPS/NAV systems for flying a GPS flight plan ending in an ILS approach. In this case, the
GPS/NAV CDI source automatically switches from GPS to VLOC when it begins receiving the
glideslope/glidepath signal. At that time, the Entegra
PFD “Nav” source also changes, and the
horizontal deviation indicator (HDI) and vertical deviation indicator (VDI) windows are
displayed on the ADI. The CDI course is automatically set to the inbound localizer course
resulting in a hands-free transition.
As long as a localizer or ILS has been selected via the Entegra
PFD “Nav” button, the HDI and
VDI will be automatically displayed when applicable localizer and glideslope signals are
received. No pilot action is required for the horizontal and vertical deviation indicators to be
displayed.
It is recommended that the inbound course be set via the
Entegra
PFD course set knob to serve as reference during
the localizer intercept and tracking. This is automatic if
the GPS/NAV system has been setup to Autoslew. The
CDI deflection will be driven by the localizer signal itself,
regardless of the course setting.
To perform an autopilot-coupled approach, ensure the
approach has been activated in the GPS selected as the
Nav source. At that point, press the NAV button on the
autopilot control head to activate Nav mode. Press the
APR button on the Autopilot control head to activate the
glideslope capture capability. The autopilot will then track
the glideslope and localizer. Refer to the autopilot user’s
guide for glideslope capture scenarios.
It is recommended that the altitude bug be set to the published approach decision height to serve
as a visual reference during the approach.
NOTE
For maximum situational awareness during all types of precision and non-
precision instrument approaches, always select and activate the approach in
the GPS/NAV. This will enable the Entegra
PFD to display the approach
waypoints on its moving map.
Upon reaching the FAF, ensure that the correct baro is entered in both the
PFD and backup altimeter. Also verify that the PFD and backup altimeter
indicate the same altitude.
Non-Precision Approaches
The Entegra
PFD is also designed to aid in the flying of non-precision approaches. Once the
published approach has been activated in the GPS/NAV system, the inbound course on the
Entegra
PFD will be automatically set to match the inbound course of the published approach.
