GPSS
GPS Steering provides a steering command to the autopilot through the HDG Datum
channel to provide for enroute, procedure turn, holding pattern, and turn anticipation
operation. GPSS through the EFD1000 E5 is only available if Label 121 is transmitted by
the GPS over the ARINC 429 bus and the optional ACU is installed.
5.4.4
GPS/ NAV Switching
Existing GPS/NAV switching from the GPS and VLOC receiver to the original HSI or Nav
indicator will be removed as the EFD1000 E5 will provide this capability. The existing GPS
and VLOC receiver will be wired directly to the EFD or ACU as per the installation drawings
in Section 9. Analog connections from the GPS and/or VLOC receiver to the autopilot will
be removed and wired per the ACU to autopilot interfaces shown in Section 9.
CAUTION – Do not remove any required GPS annunciation on the external NAV/GPS switch
assembly as the EFD1000 E5 does not support any GPS annunciation (i.e., WPT,
APPR, TERM, INTEG).
