EFD1000 C3 Pro PFD Pilot’s Guide
For example, suppose you use a GNS-430 to y a GPS ight plan and have an ILS
instrument approach loaded and active, and the GNS-430 is set for Auto ILS CDI
changeover once you are established inbound on the nal approach course. With GPSS
enabled on the PFD and the autopilot in HDG mode, the GPSS will steer the autopilot
laterally through the ight plan using GPS, even after the GNS-430 CDI automatically
switches to VLOC, and the PFD navigation source similarly switches to VLOC. However,
until you switch the autopilot into the Approach mode, it will not arm or capture the
glideslope to y the ILS approach. This feature is particularly useful for autopilots that
do not automatically transition from Heading mode to Nav mode when the selected
course is intercepted.
When ying an ILS on a WAAS GNS-430W, the autopilot in HDG mode can use the GPSS
to y the full course reversal automatically, and the GNS-430W will automatically switch
to VLOC once established inbound to the Final Approach Fix. But the pilot must then
engage the Approach mode on the autopilot to track the localizer and couple to the
glideslope.
WARNING
It is your responsibility as Pilot in Command to ensure
that you are familiar with the operation of all installed
equipment. Operation of the PFD in IMC conditions
should not be attempted unless you are procient in its
use and operation, as describedherein.
NOTE
Refer to the autopilot systems Aircraft Flight Manual
Supplement and/or POH for details regarding use and
operation of the autopilot system.
Examples here are provided for reference only, based on
operation of the Bendix/King KFC-200 autopilot, and
actual operation may vary depending on the autopilot
system installed in your aircraft.
