NOTE
Some IFR GPS navigators include ILS approaches
in their procedures database. GPS may be used to
navigate the initial segments of the ILS approach, but
the pilot must switch to VLOC navigation outside the
FAF and before glide slope intercept.
Some integrated GPS/NAV receivers can be configured
to switch automatically, and the PFD Selected CDI
Navigation Source will follow automatically. It is the
pilot’s responsibility to verify that the PFD CDI source is
correctly set to VLOC# before reaching either glide slope
intercept or the FAF.
NOTE
The PFD supports GPS LPV approaches (Approaches
with Vertical Guidance) by providing the autopilot
with GPS lateral and vertical deviation signals that are
identical to those typically provided by an ILS radio.
To fly GPS LPV approaches, configure and operate the
autopilot as you would for an ILS approach.
9. Monitor the PFD CDI localizer deflection and verify that, upon intercepting
the localizer, the autopilot captures the final approach course and switches
to the Approach (APPR) mode.
10. Monitor the autopilot localizer tracking performance. Upon intercepting the
glide slope, verify that the autopilot captures glide slope and initiates
a descent.
GPS APPR Mode Operation – WAAS GPS Underlay to ILS Approach With ATC
Vectors to Final
1. With a valid ILS approach loaded and activated in the GPS, use the CDI Source
Select Button to couple the PFD GPS to the CDI
2. Verify that the correct ILS frequency is tuned.
3. Set the Heading Bug to the heading assigned by ATC
4. Disable GPSS via the GPSS Hot Key.
5. Engage the autopilot in Heading (HDG) mode and verify that the aircraft turns
to the Selected Heading.
6. When cleared for the approach and given the final heading to intercept
the final approach course by ATC, arm the autopilot’s Approach (APPR) and
Altitude (ALT) Hold modes.
7. Monitor the CDI and aircraft track to verify that the autopilot intercepts the
final approach course and begins to track inbound to the FAF.
8. Use the PFD CDI Navigation Source Select Button to change to the VLOC
source for the approach (if not done automatically by the GPS/nav receiver).
9. Monitor the PFD CDI localizer deflection and verify that, upon intercepting
the localizer, the autopilot captures the final approach course and switches
to the Approach (APPR) mode.
10. Monitor the autopilot localizer tracking performance. Upon intercepting the
glide slope, verify that the autopilot captures the glide slope and initiates a
descent to.
