 EIS (DMC & DU) - Page 9 

EIS – System description - EFIS Electronic Flight Instrument System (5) PFD control The switch enables to control the barometric setting in inches of mercury ( In Hg) or in hecto Pascal (hPa). The baro-setting knob can be pulled or pushed in order to set the barometric setting to either STD (standard) or QNH or QFE (1). The FD pushbutton is used to engage/disengage the Flight Director (2), while the LS pushbutton is used to display LS information on the PFD (3). (1) The QFE setting is optional (pin programming) (2) When the FD push-button is lighted the FD bars are in view on the PFD (assuming active modes are negaged in the corresponding AP/FD system. When the FD push-button is pressed to set the FD off, the FD bars are out of view. Basically at power on, after the initialization process of the corresponding FMGC, the FD are automatically engaged and the push-buttons are lighted on. (3) When LS push-button is used the corresponding PFD displays Localizer and Glide/Slope deviation scales whatever is the used landing system, ILS (Instrument Landing System) or MLS (Microvawe Landing System)

 EIS (DMC & DU) - Page 10 

EIS – System description - PFD Primary Flight Display (1)

Typical PFD displays - Attitude, Airspeed, Altitude and Heading information The PFD displays the main flight information necessary for the control of the A/C, arranged in the basic T configuration :

A/C symbol, pitch and roll indications, flight path angle and drift angle, guidance symbols (Flight or Flight Path Director). An altitude scale and vertical speed scale provide the pilot with the A/C actual baro altitude and baro/inertial vertical speed, plus the altitude and flight level selections.

Airspeed scale provides the pilot with the A/C actual indicated Air Speed, and with all the characteristic airspeed limitations. Characteristic airspeed limitations are computed by the FACs. Refer to chapter FE ( Flight Envelope ) of the ATA 22 chapter for more information.

Baro setting reference indication A heading scale provides the pilot with the A/C actual heading, actual track, and relative selections.

 EIS (DMC & DU) - Page 11 

EIS – System description - PFD Primary Flight Display (2)

A full Flight Mode Annunciation ( FMA ) provides the pilot with the engaged modes, the various armed/active longitudinal and lateral modes,and the AP/FD/A-THR engagement status. A vertical and lateral deviation scales give GLIDE/SLOPE - LOCALIZER or V/DEV -L/DEV (for further references other than LS) raw data. These deviation scales and indexes are only activated once the LS pushbutton on the FCU has been pressed in. FD ( Flight Director ) bars FD tendency bars are displayed once the FD is engaged ( FD pushbutton pressed in and lighted on the FCU ). FD bars are composed of three bars: for pitch, roll and yaw . ( for more information about FD, please refer to Flight Director chapter in the ATA 22 section ). Additional flight information can be added on the PFD image, such as the radio altitude which will be displayed in digital form below the horizon line during landing, etc.

In normal operation, each DMC, with respect to sensor and computer inputs, acquires data/parameters through its ONSIDE sources to gather all necessary data in order for the display unit driven by the DMC to generate all graphic symbologies related to a particular image. In normal operation, each DMC drives two display units as follows: - The DMC 1 drives the CAPT PFD DU , CAPT ND DU, EWD, and SD. - The DMC 2 drives the F/O PFD DU and the F/O ND DU, - The DMC 3 is used in case of reconfigurations ( see chapter 5.7 System Reconfiguration ). In order to ensure the greatest availability of the displayed data, the fully redundancy architecture of the system enables three types of reconfiguration in case of any component failure: - In case of single or multiple DU failures, - In case of single or multiple DMC failures, - In case of external (sensor/computer) information source failures.

EIS – On Board maintenance

ON BOARD MAINTENANCE & BITE

 EIS (DMC & DU) - Page 49 

EIS – On Board maintenance – BITE (DMC and DU) General

There are 3 types of Built-In Test: - Power-On Self Test ( POST ): this includes software and hardware testing activated at power on. The objective of the POST is to ensure of the validity of the equipment - Continuous Built-In Test ( CBIT ): the CBIT includes recurrent tests. The objective is to detect internal or external, to memorize the abnormal event, to analyze it and then to transmit the failure report to the centralized maintenance system i.e. the CFDIU (Centralized Fault Interface Unit - Initiated Test ( IBIT ): interactive test called IBIT are activated while the aircraft is on ground, the CFDS (Centralized Fault Display Display System) switched to MENU mode, the INST (Instrument) page selected and finally the EIS 1 (2) or (3) page has been selected by the MCDU operator.

 EIS (DMC & DU) - Page 50 

EIS – On Board maintenance – BITE (DMC and DU) – Power On (1/4)

1 : after power-on, DMC and DU acquire flight/ground information during 300 ms and pin-programming. 2 : after 300 ms, DMC and DU activate the POST mode. DUs display the SELF TEST IN PROGRESS green message. 3 : DMC, after correct completion of the POST mode, activates the OPER mode and sends operational data to DUs. DUs, because of their internal hardware tests duration, are always activating the POST mode tests and displaying the SELF TEST IN PROGRESS green message.

 EIS (DMC & DU) - Page 51 

EIS – On Board maintenance – BITE (DMC and DU) – Power On (2/4)

4 : DUs, after correct completion of the POST mode, activate the OPER mode. During this phase, DUs send software version and link check wordstring and activate the software version check process and the A629 inputs validity check process. During this phase (short test), nothing is displayed on DUs. DMC is always sending operational data to DUs. 5 : after correct completion of theses checks, DUs display an operational image. The duration of these tests is equal to 40 seconds for the LCDU and 35 seconds for the DMC.

 EIS (DMC & DU) - Page 52 

EIS – On Board maintenance – BITE (DMC and DU) – Power On (3/4) SELF TEST IN PROGRESS (MAX 40 SECONDS)

During the POST mode, or in case of interruption during the POSTs, when the DU starts again and if the results of the previous POST was OK, the SELF TEST IN PROGRESS (MAX 40 SECONDS) green message is displayed, when the required resources are available.

INVALID DISPLAY UNIT

If the required resources are available, the INVALID DISPLAY UNIT amber message is displayed when: - a fatal failure is detected during the DU POST, - or in case of interruption during the POSTs, when the DU starts again and if the results of the previous POST was KO.

F

If the hardware resources to display a failure message, are not available, the hardware pattern F is displayed in amber. If any failure is detected during the start-up phase (for instance if one of the two graphic channels is out of order), the software orders directly to the hardware the display of the hardware pattern F.

Notes: message displayed are largely blow-up and does not correspond to the actual text size

INVALID DATA

In case of DMC POST activity n° 1, 2, 3, or 5 failure the DU displays the INVALID DATA amber message.

DMC VERSION INCONSISTENCY

In case of DMC POST activity n° 4 failure the DU displays the DMC VERSION INCONSISTENCY amber message.

Notes: message displayed are largely blow-up and does not correspond to the actual text size The POST mode activities and their sequence for DMC are: 1) hardware P/N compatibility check (complete), 2) pin program parity check (complete), 3) equipment location check (complete), 4) engine type validity check (complete), 5) internal hardware tests (complete/light). The POST mode activities and their sequence for DU are: 1) hardware P/N compatibility check (complete), 2) pin program parity check (complete), 3) equipment location check (complete), 4) internal hardware tests (complete/light).

 EIS (DMC & DU) - Page 54 

EIS – On Board maintenance (1) The DMC or DU delivered to you (as spare equipment or after a repair) does not content any software or may content a software which is not the latest one. As a consequence, once a DMC or a DU is installed on board the aircraft it is necessary to load the software into it You can do this software loading in three manner/

Tele-loading from an external data-loader (aircraft data loader or portable data loader) into a DMC. This operation is called DMC Uploading. Tele-loading from a DMC into DUs is called DU Cross-loading, Tele-loading from a DMC into another DMCs is called DMC Cross-loading.

EIS – On Board maintenance (2) The following figure gives examples of the 3 different tele-loading sub-functions. For the DU cross-loading subfunction, the maintenance operator has to configure the DUs on the Emitter DMC by using the DMC reconfiguration •

Note: The cross-load of the 6 DUs in one operation is not possible. To load the 6 DUs, 2 cross-loading operations from 2 different DMCs are needed. These 2 operations have to be done one after the other (2 DMCs can not be in cross-loading mode at the same time).

 EIS (DMC & DU) - Page 58 

EIS – On Board maintenance (5) – Tele Loading

Tele-loading Description : During a tele-loading (Uploading or Cross-loading), the loaded LRU: • - manages the dialogue with the loader, • - manages its FPROM (erase, write on the FPROM), • - behaves as if it was not powered regard to the other computer, it does not emitting on the output buses (except the bus used for tele-loading) and sets discrete signals in the open state. When the transfer of the software to the LRU is completed, the LRU checks the integrity of the tele-loaded software. If the integrity checks of the tele-loaded software are false, the LRU: • - sends its part number hardware, a part number software corresponding to a LRU without operational software and its serial number every 50 ms on the A629 bus, • - stays in TELE mode and waits for a new tele-loading request.

L

E

• Note: During the tele-loading, a DU displays the large L cyan letter. • Before tele-loading the DU without software displays the large E white letter.

 EIS (DMC & DU) - Page 59 

EIS – On Board maintenance (6) - Tele Loading •

The duration of the uploading depends on the protocol used (A615-3 or A615A) and on the internal behavior of the data-loader.

•

The total duration of any kind of cross-loading (1 to 2 DMCs or 1 to 6 DUs) is less than 10 minutes. The crossloading duration includes the time needed for data transfer on A629 buses, data writing on FPROM and integrity checks of tele-loaded software (any manual operation by the operator is not part of the cross-loading duration).

When a DMC cross-loads several LRUs at the same time, if the cross-load of one LRU is aborted, the DMC considers as aborted only the cross-loading of this LRU and the DMC continues the cross-loading of the other LRUs. •

Note: There is no requirement on uploading duration for the EIS. Cross-loading duration is given for a 16 Mbits software and if the FPROM writing or erasing time is typical, i.e. the FPROM is used in normal conditions (temperature, voltage, wearing state of the FPROM).

 EIS (DMC & DU) - Page 60 

EIS – On Board maintenance (7) General • The (OMS) On board Maintenance System through MCDUs, installed in the cockpit, provides maintenance operator with the possibility to consult A/C systems status and to activate a set of tests. •

This function is accessible when the OMS is in MENU Mode. Note that this mode correspond to the INTR mode of the new EIS system. Note this mode is available on ground only.

•

During the INTR mode and if no other image is requested, each DU, that is connected to a DMC which is in maintenance mode, displays the MAINTENANCE MODE green message.
