INTEGRATED MODULAR AVIONICS DESCRIPTION (3)General

Thanks to the new avionics concept Integrated Modular Avionics (IMA),most of the conventional LRU functions are done by avionics applications.These independent applications are hosted in shared IMA modules, calledCore Processing Input/Output Modules (CPIOMs).As a consequence, IMA concept reduces the maintenance cost due to lessspare computers.Each CPIOM integrates new hardware and software technologies andhosts these independent applications in the same computing and memoryresource, and also supplies an Input/Output interface service to some ofthe conventional avionics.Moreover, in order to satisfy the high demand of conventional avionics,this service capability has been increased thanks to additional IMAmodules called Input/Output Modules (IOMs).CPIOMs and IOMs are Line Replaceable Modules (LRMs).These LRMs dialogue through the Avionics Data CommunicationNetwork (ADCN) by the means of communication technology developedfrom a non-aeronautical standard, which has been adapted to aviationconstraints.This technology is called Avionics Full DupleX Switched Ethernet(AFDX).

INTEGRATED MODULAR AVIONICS DESCRIPTION (3)"Mirror" IOM Principle

An IOM converts non-AFDX data, coming from conventional LRUs,into AFDX data used within the ADCN and vice versa.There are 8 IOM-A connected to the ADCN. 4 IOMs on side 1 and 4IOMs on side 2.The IOM-A1/2/3/5/7 are "mirror" IOMs of IOM-A2/4/6/8 and vice versa.A LRU such as computer, sensor, etc., that exchanges message withADCN subscribers must use both "mirror" IOMsFor an A/C system composed of more than one LRU (e.g.: Navigationsystem), each LRU (e.g.: RA) of this system dialogues through "mirror"IOMs different than those used by the other LRUs.Thus, the LRU and the ADCN subscriber send or receive redundantmessages.In case of one IOM loss, the communication between a LRU and anADCN subscriber is not lost thanks to the "mirror" IOM.

AVIONICS DATA COMMUNICATION NETWORK DESCRIPTION (3)General

The Avionics world gathers the aircraft systems supplied within 7functional areas, related to:-Flight Controls and Auto Flight,-Cockpit,-Engines control,-Energy,-Pneumatic and Cabin,-Fuel,-and Landing Gear.These functional areas group computers like LRUs, IOMs, CPIOMsand/or LRUs with AFDX interface that share a common interest orcharacteristics.These computers exchange operational and maintenance data.For most of them, this exchange is done through the Avionics DataCommunication Network (ADCN). The ADCN is composed of tworedundant networks, A and B. Both networks are composed of 8 AFDXswitches, connected to each other with AFDX cables.The ADCN uses AFDX technology based on the Ethernet protocoladapted to aeronautical constraints. It is used for the exchange ofoperational, maintenance and loading data between the ADCN subscribers,which are LRUs with AFDX interface and the LRMs.The subscribers can communicate at speeds 10 or 100 Mbits/s. This typeof network is extensible and does not need specific connections for newsubscribers.

AVIONICS DATA COMMUNICATION NETWORK DESCRIPTION (3)The Virtual Link Philosophy

The ADCN is a set of AFDX switches interconnecting several ADCNsubscribers.Each ADCN subscriber has an input/output interface called AFDX EndSystem. This AFDX End System lets the subscriber send and receiveAFDX frames to and from another(s) ADCN subscriber(s), through theADCN. This is, by encoding the computer data into AFDX frame fortransmission or decoding AFDX frame into computer data after reception.This AFDX End System duplicates AFDX frames in transmission andkeeps the first incoming one in reception. This duplication increases theavailability of A/C system data by sending them simultaneously on bothredundant networks A and B.Due to the AFDX technology, this data exchange uses a new conceptcalled "Virtual Link"(VL).The VL is similar to an unidirectional "pipe" through the ADCN.The Virtual Link:-Carries AFDX frame,-Has one specific identification,-Is sent by one transmitter only,-Is received by one or more subscribers in receive mode,-Goes on both redundant networks A and B, through a specific routing.This routing depends on receivers (e.g.: application(s), computer(s),sensor(s), etc.) the emitter wants to send data.Each AFDX switch has a switching function. This function receives theVL coming from one emitter, routes it to the appropriate output port(s)based on the configuration table.An AFDX switch has 24 AFDX input/output ports.To sum up, the emitter sends a VL simultaneously to both first AFDXswitches (one per network), then, each AFDX switch, according to theVL identification and its configuration table, routes the VL to thefollowing AFDX switch and so forth till the receiver.

AVIONICS DATA COMMUNICATION NETWORK FAILURES DESCRIPTION (3)Single AFDX Cable Loss

In case of a single AFDX cables loss, the non-degraded network istransmitting the A/C system data.It is a class 4 fault. If this failure is not repaired prior to 1000 flight hours,it becomes a class 1 level 1fault.There is no functional effect on A/C systems. According to MasterMinimum Equipment List (MMEL) this failure is a GO with Crectification interval.
