PRIMARY FLIGHT DISPLAY (PFD)

GPSS

The GDU 620 will send the GPSS commands from the displayed GPS source to

the autopilot. For example, if GPS 1 is displayed on the HSI, the GPSS

commands from GPS 1 will be sent to the autopilot. Refer to the Airplane

Flight Manual and autopilot system documentation for instructions on how to

use the autopilot' s GPSS function.

NOTE: GPSS commands are not sent to the autopilot when a VLOC

source is displayed on the HSI.

In installations that use GPSS emulation in combination with the "heading"

mode of the autopilot, GPSS mode may be toggled on/off with an external switch

or by pressing and holding the HDG key on the PFD. If the installation uses the

HDG key on the PFD, the PFD knob window will display the GPSS/HDG mode

options.

NOTE: The GDU 620 has the ability to emulate GPSS roll steering for

autopilots that do not support GPSS. The GDU 620 emulates GPSS by

sending headings to the autopilot that guide turn anticipation.
