The ADR also interface with the crew through direct links between GADIRUs and: - The CDS for the barometric reference setting TRAINING - The GADIRS Control Panel (ADR pushbuttons), within the Integrated Control Panel System (ICPS), for fault indication and disabling - The Air Data selector in the Source Switching Panel (SSP) for source switching. It also sends its command via IOMs and ADCN to the user systems (CDS, HUDS, etc) to change their selection of air data input A command from the ICPS Anti-ice Control pushbutton is used to activate the ice protection of the ISP, MFP and SSA probes while USE the aircraft is on the ground. In flight the ice protection is managed automatically.

NTCSS Release 2023-01 51_ATA34_Lv2&3_CAT B2_P_JUN21.pdf  GPS Air Data Inertial Reference SubSystem - A400M Training Manual Description & Operations General Description IR Architecture The IR part of each GADIRU measures the aircraft accelerations from their internal sensors: - The axis-orientated accelerations are sensed by means of the Accelerometers, which are linear acceleration sensors - The corresponding ax angular velocity Pitch, Roll, and Yaw are sensed by means of the Gyros From the sensors, the IR constantly computes the A/C attitude (Pitch, Roll, and Yaw) and, by the detection and measurement of motions, speeds and accelerations, can deduce at any time the A/C position from an initial reference point. GADIRS uses also position data from its internal, dedicated Military GPS and from the Civil GPS of the Multi Mode Receiver (MMR) system. The GADIRUs merge and filter the measurements from all the different sources (IR, military GPS and/or civil GPS) to provide a hybrid solution for position. The GADIRUs send inertial data and hybrid position, via ADCN and through direct links to: - HUDS - Other A/C systems The GADIRUs also send inertial data to the Integrated Standby Instrument System (ISIS). For the link with the crew, the IR uses the HMI resources provided by the FMS and CDS, which interchange data via ADCN with the GADIRUs. The IR also interfaces with the crew through direct links between GADIRUs and: TRAINING - GADIRS Control Panel (IR pushbuttons), within the ICPS, for fault indication and disabling - The Attitude/Heading selector in the SSP for source switching. It also sends its command via IOMs and ADCN to the user systems (CDS, HUDS) to change their selection of air data input.

NTCSS Release 2023-01 51_ATA34_Lv2&3_CAT B2_P_JUN21.pdf  GPS Air Data Inertial Reference SubSystem - A400M Training Manual Description & Operations General Description GPS and Time Architecture (Standard A/C Configuration) The GPS provided by GADIRS is a military GPS that delivers data with superior accuracy than the civil GPS. The GADIRS receive the GPS signals through two kinds of antennas: - FRPA - CRPA, which is linked to an electronic unit called Controlled Reception Pattern Antenna Unit (CRPAU). Two GPS outlets provide the GPS signal from the two CRPAUs for use by portable GPS units. The GADIRU sends GPS data via ADCN to the A/C systems. For the link with the crew, the GPS uses the HMI resources provided by the FMS and CDS, which interchange data via ADCN with the GADIRU. The GADIRUs also receive commands through direct links from the Antenna Selection Switch, which is within the ICPS. It allows the crew to switch between FRPA and CRPA. The switch status is also transmitted to other systems. Thanks to GPS function, the GADIRS provides the “system time”. It is achieved by the Clock function of the GADIRU. According to crew selection (internal or external) from CDS, the time source for the Clock is either the military GPS of the GADIRU or the civil GPS of the MMR. The flight crew also can manually set the Clock. The “system time” is the unique time reference on board of the A/C. It is sent via ADCN to CDS to be displayed and to other systems.

Depending on conditions (electrical emergency and SSP Air Data selector) they can be also supplied by AC Emergency Bus and DC Essential Bus. The ICPS provides to all 3 GADIRUs the commands for power ON/OFF. When the OFF state is commanded, each GADIRU starts internally a power down sequence and disconnects itself from the power supply. The OFF command is triggered only on ground.

In normal electrical configuration: - GADIRU1 is powered with 115 VAC from the AC Emergency Bus. - GADIRU2 is powered with 115 VAC from the SEPDC 2. - GADIRU3 is powered with 115 VAC from the SEPDC 1. In case of loss of main electrical generation, the principle is to supply two GADIRUs (GADIRU 1 and 3) from the AC Emergency Bus: - GADIRU1 is still powered with 115 VAC from the AC Emergency Bus. - GADIRU2 is no longer powered with 115 VAC since normal power from SEPDC 2 is lost. - GADIRU3 is powered with 115 VAC from the AC Emergency Bus, after automatic switching ensured by the Emergency Relay. In case of total loss of 115 VAC supply, the Hot Bus Essential will supply the GADIRU1 and 3 on 28 VDC Back-up Power input through respective Time Delay Opened (TDO) Relays. These relays remain activated by a control signal supplied by the DC Essential Bus. If the DC Essential Bus is lost, the 28 VDC Back-up power supply is ensured through a 10 seconds timer in the TDO Relays, time TRAINING necessary for the Ram Air Turbine (RAT) deployment.

The GADIRS control panel is made of six illuminated pushbuttons: one IR and one ADR for each of the three GADIRUs. In case the GADIRU internal monitoring detects erroneous IR and/or ADR data, the corresponding “FAULT” indication is illuminated. When one of the switches is pressed, the corresponding GADIRU stops IR or ADR data transmission to ADCN, and the “OFF” indication is illuminated (data are still processed, but not transmitted). The corresponding GADIRU is not actually switched off when one of these switches is pressed.

The SSP contains two rotary switches that determine the GADIRU that is used as the source of data: - Attitude and Heading Selector, which is related to the IR part within the GADIRU - Air Data Selector, which is related to the ADR part within the GADIRU In normal position the data parameters displayed on the CDS and HUD Displays come from the one side GADIRU, and the GADIRU 2 for the 3rd crewmember station display. Other positions of the two switches allow the crew to reconfigure one side of the cockpit to display parameters from GADIRU 3 instead of parameters coming from the normal GADIRU (1 or 2). Whatever the position of the switch, the 3rd crewmember station uses the same source system as the right side of the cockpit.

We are now going to analyze in details what the GADIRU is and how it works. As we know, the main functions of GADIRS are ADR, IR, GPS, and CLOCK. During this lesson we’ll talk also about the Hybridization function, which is a computation function.

The ADR part of each GADIRU is supplied by data coming from its associated set of air data probes. A set of Air Data Probes is composed of: - 1 Multi Function Probe (MFP), - 1 Side Slip Angle Probe (SSA), - 2 Integrated Static Probes (ISP), - 1 Outside Air Temperature Sensor (OAT) All probes except OAT transmit the air data parameters to its associated GADIRU via ARINC 429 buses. They also receive de-icing automatic activation signals from the GADIRUs via ARINC 429 buses and a discrete signal from the Probe and Window Heat push button dedicated to manual De-icing activation.

Compared with the CIV GPS, the MIL GPS provides: 1. Increased position accuracy 2. Additional time data functionality (Military Code Time) 3. The cryptography functionality 4. Increased resistance against jamming and spoofing environments. The MIL GPS operates in the following modes: - A military mode called P(Y) (Precise encrYption) using cripto keys to provide a precision positioning service with robustness against spoofing and jamming - Civil Coarse Acquisition (C/A) mode to provide a standard positioning service if P(Y) mode is not available.
