•
GIA 63(W)
(2) – Functions as the main communication hub, linking all LRUs with the on-side PFD. Each
GIA 63W contains a GPS WAAS receiver, VHF COM/NAV/GS receivers, a flight director (FD) and system
integration microprocessors. Each GIA 63W is paired with the on-side PFD via HSDB connection. The GIA
63Ws are not paired together and do not communicate with each other directly.
GDC 74A
– The Air Data Computer (ADC) processes data from the pitot/static system and outside air temperature
(OAT) sensor. The ADC provides pressure altitude, airspeed, vertical speed, and OAT information to the
G1000 System, and it communicates with the primary IAU, displays, and AHRS using an ARINC 429 digital
interface.
•
GEA 71
– The Engine Airframe Unit receives and processes signals from the engine and airframe sensors. This
unit communicates with both IAUs using an RS-485 digital interface.
•
GTX 33
– The solid-state Transponder provides Modes A, C, and S capability and communicates with both IAUs
through
an RS-232 digital interface.
