•
GSR 56
(1) – The Iridium Transceiver provides voice communication by means of pilot and copilot headsets.
The unit can also send and receive data over the Iridium satellite network. The GSR 56 is connected to the #1
GIA 63W with an RS-232 digital interface.
•
GCU 478
(1) – Provides the Flight Management System (FMS) controls for the PFD and MFD through an
RS-232 digital interface.
•
GMC 705
(1) – Provides the controls for the GFC 700 AFCS through an RS-232 digital interface allowing
communication with the PFD and MFD.
•
GTP 59
(1 or 2) – The Temperature Probe provides Outside Air Temperature (OAT) data to the primary GDC
74A.
•
GSA 80
(1),
GSA 81
(2), and
GSM 85A/86
(3) – The GSA 80 servo is used for the automatic control of yaw,
while the GSA 81 servos are used for the automatic control of pitch and roll. These units interface with each
GIA 63W. The GSM 85A/86 servo gearbox is responsible for transferring the output torque of the GSA 80/81
servo actuator to the mechanical flight-control surface linkage.
