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.

The ADR and IR systems of each
ADIRU operate independently, and failure

The ADR part provides various air data to the
Flight Management and Guidance Computers
(FMGC) and other users.
The air data provided include; Mach,
Airspeed, Temperature, Overspeed warnings,
barometric altitude, and angle of attack.

The three ADIRS are controlled through the
ADIRS panel located on the overhead panel.

Their initialization is done through the two
MCDU located on the pedestal.

Independent data are supplied by each ADIRU.
Let’s see an example of this.

The panel is divided into two parts. The upper

ADR.
The three rotary mode selectors have control
over both the IR and the ADR.

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

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.

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.

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.

The system selector enables the crew to switch

We will select system 3 for you. Notice that the
display now contains the present position, or

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.

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.

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.
