2.2.6 GIA 63W/GIA 64W Integrated Avionics Unit
The Integrated Avionics Unit (GIA) functions as the main communication hub, linking all
LRUs with the on-side PFD. Each GIA contains a GPS SBAS receiver, VHF COM/NAV/
GS receivers, a Flight Director (FD) and system integration microprocessors. The GIAs
are not paired together and do not communicate with each other directly. An optional
configuration is possible which will also interface with older equipment with analog,
synchro, and other unique interfaces.
2.2.7 GEA 71 and GEA 71B Engine and Airframe Interface
The GEA71(B) Engine Airframe Unit is a microprocessor based input/output Line
Replaceable Unit (LRU) which monitors sensor inputs and drive annunciator outputs for
aircraft airframe and engine systems.
The GEA 71(B) interfaces with various sensors on the aircraft and communicates
airframe and engine information through an RS-485 digital interface to the GIA. The
GIAs then interface with the PFDs and the MFD. The MFD displays engine
instrumentation and the PFDs display airframe alerts provided by the GEA 71(B).
Engine/airframe instrumentation is also displayed on the PFDs and/or MFD when the
system is in reversionary mode.
The displays serve as the GEA 71(B) user interface. All configuration settings are
controlled by software settings accessed by the MFD and PFDs.
The GEA 71(B) uses a configuration module temperature sensor and a thermocouple
sensor housed in a backshell assembly to monitor backshell junction temperatures.
The GEA 71(B) has Analog Inputs (18), Engine Temperature Analog Inputs, Transducer
Excitation Outputs, RS-485 interfaces, Discrete Inputs, Digital Inputs, and Aircraft Power
Inputs. The GEA 71(B) has 9 Annunciator Outputs and 2 Differential Counter Inputs and
2 Extended Common Mode Analog Inputs. The GEA 71(B) operates with 28 V DC
nominal aircraft power.
2.2.8 GTX 345R Transponder
The GTX 345R Transponder operates on radar frequencies, receiving ground radar or
TCAS interrogations. The transponder transmits a coded response of pulses to ground
based radar on a frequency of 1090 MHz. The transponder has IDENT capability and
replies to ATCRBS Mode A, Mode C and Mode S All-Call interrogation. It also includes
ADS-B In which provides TISB and FIS-B data via UAT and 1090 MHz.
The transponder offers an optional Garmin altitude encoder to meet the required
barometric pressure altitude source and an optional internal GPS/SBAS source to meet
the required GNSS position source integrity for ADS-B Out.
