NAVIGATION MENU ADIRS presentation 1/45 NAVIGATION MENU ADIRS presentation 2/45 ADIRS The purpose of the Air Data Inertial Reference System (ADIRS) is to provide air data and inertial information to the EFIS system, the FMGC and other users. OTHER USERS FMGC EFIS NAVIGATION MENU ADIRS presentation 3/45 ADIRU 1 ADIRU 3 ADIRU 2 The A320 is equipped with three separate but identical Air Data Inertial Reference Units. NAVIGATION MENU ADIRS presentation 4/45 AIR DATA ADIRU REFERENCE NAVIGATION MENU ADIRS presentation 5/45 ADIRU INERTIAL REFERENCE Each ADIRU combines an Air data reference computer, or ADR and a laser gyro inertial reference system, or IR. AIR DATA REFERENCE NAVIGATION MENU ADIRS presentation 6/45 ADIRU INERTIAL REFERENCE The ADR and IR systems of each ADIRU operate independently, and failure of one system will not cause failure of the other. AIR DATA REFERENCE NAVIGATION MENU ADIRS presentation 7/45 AOA TAT PITOT STATIC AIR DATA REFERENCE The ADR part receives information from aircraft probes and sensors.

The air data provided include; Mach, Airspeed, Temperature, Overspeed warnings, barometric altitude, and angle of attack.

Grroouunndd ssppeeeedd,, The IR part provides inertial data to the FMGC, EFIS and other users. The inertial data provided include : Track, Heading, Acceleration, Flight Path Vector, Airplane Position, Ground speed and Attitude. NAVIGATION MENU ADIRS presentation 10/45 The three ADIRS are controlled through the ADIRS panel located on the overhead panel. NAVIGATION MENU ADIRS presentation 11/45 Their initialization is done through the two MCDU located on the pedestal. NAVIGATION MENU ADIRS presentation 12/45 And by two of the switches on the SWITCHING panel located at the front of the pedestal. NAVIGATION MENU ADIRS presentation 13/45 ADIRU 1 ADIRU 3 ADIRU 2 Independent data are supplied by each ADIRU. Let’s see an example of this. NAVIGATION MENU ADIRS presentation 14/45 ADIRU 1 ADIRU 3 ADIRU 2 NAVIGATION MENU ADIRS presentation 15/45 In the EFIS system ADIRU 1 supplies the captain’s EFIS, and ADIRU 2 supplies the first officer’s EFIS. ADIRU 1 ADIRU 3 ADIRU 2 NAVIGATION MENU ADIRS presentation 16/45 ADIRU 1 ADIRU 3 ADIRU 2 NAVIGATION MENU ADIRS presentation 17/45 ADIRU 3 is available as a stand-by to either EFIS system via the switching panel. Use of the switching panel will be covered in the abnormal section.

NAVIGATION MENU ADIRS presentation 19/45 Inertial Reference Section Air Data Reference Section ADIRS Selectors The panel is divided into two parts. The upper section for the IR and the lower section for the ADR. The three rotary mode selectors have control over both the IR and the ADR. NAVIGATION MENU ADIRS presentation 20/45 ADIRU1 ADIRU3 ADIRU2 The controls and indicators for the individual ADIRU are grouped and arranged in the order of 1,3 and 2. NAVIGATION MENU ADIRS presentation 21/45 NAVIGATION MENU ADIRS presentation 22/45 Each ADIRU has an associated IRS rotary mode selector. In the ‘OFF’ position, the ADIRU is not energized, so ADR and IR data are not available. The three ADR switches normally remain on, but they can be selected off in response to ECAM procedures. In the ‘NAV’ position the ADIRS are energized. The ‘NAV’ position is the normal mode of operation and full inertial data is provided to the aircraft systems. NAVIGATION MENU ADIRS presentation 23/45 The ON BAT light illuminates to inform the crew that the ADIRU system is being powered by aircraft battery only. The light also illuminates for a few seconds at the beginning of a full alignment as a test of the battery circuit. We will discuss this further in Normal and Abnormal operation modules. ALIGN ALIGN ALIGN NAVIGATION MENU ADIRS presentation 24/45 ALIGN ALIGN ALIGN NAVIGATION MENU ADIRS presentation 25/45 Each Inertial Reference Unit has an associated indicator. The ALIGN light illuminates steady white when the respective IRU is operating normally in ALIGN sequence mode. ALIGN ALIGN ALIGN NAVIGATION MENU ADIRS presentation 26/45 NAVIGATION MENU ADIRS presentation 27/45 NAVIGATION MENU ADIRS presentation 28/45 The ALIGN light flashes white if : • There is an IRU alignment fault, • No present position entry has been made after 10 minutes, • The difference between the position at shutdown and the entered position exceeds 1 degree of latitude or longitude. NAVIGATION MENU ADIRS presentation 29/45 Present position information for ADIRS alignment is normally entered via the INIT page of the MCDU. This method will be explained in the normal operation module. ADIRU 1 ADIRU 3 ADIRU 2 NAVIGATION MENU ADIRS presentation 30/45 NAVIGATION MENU ADIRS presentation 31/45 NAVIGATION MENU ADIRS presentation 32/45 NAVIGATION MENU ADIRS presentation 33/45 The system selector enables the crew to switch the display off, or select one of the three ADIRU for display. We will select system 3 for you. Notice that the display now contains the present position, or PPOS, information for ADIRU3.

NAVIGATION MENU ADIRS presentation 36/45 ALIGN ALIGN ALIGN NAVIGATION MENU ADIRS presentation 37/45 ALIGN ALIGN ALIGN With HDG selected during IRS alignment, the time remaining until alignment is complete is displayed. This is shown by a TTN, Time To Nav, indication. Currently the display is showing that there are 10 minutes remaining until the alignment is complete. NAVIGATION MENU ADIRS presentation 38/45 ALIGN ALIGN ALIGN NAVIGATION MENU ADIRS presentation 39/45 ALIGN ALIGN ALIGN The ‘STATUS’ position displays IRU status and guidance to the pilot in abnormal situations. For example the current display is showing ENTER PPOS asking you to enter the present position of the aircraft. NAVIGATION MENU ADIRS presentation 40/45 The ‘TRACK AND GROUND SPEED’ position indicates the true track and ground speed of the aircraft. NAVIGATION MENU ADIRS presentation 41/45 NAVIGATION MENU ADIRS presentation 42/45 NAVIGATION MENU ADIRS presentation 43/45 The ‘TEST’ position tests the lights on the keyboard and produces a test pattern in the main display as shown. NAVIGATION MENU ADIRS presentation 44/45 The keyboard is a standby facility allowing, for example, entry of present position for alignment of the IRS. You will see an example of the keyboard use in abnormal operation. NAVIGATION MENU ADIRS presentation 45/45 The ‘ATT’ position is an IR mode providing only heading and attitude information in case of loss of navigation capability. We will discuss this further in Abnormal operations.
