information from two Total Air Temperature sensors.
NOTE: that ADIRU3 receives the Total Air Temperature
(TAT) from the TAT 1 sensor which is composed
of two elements.
WATER DRAIN
The probes are installed in such a way that their
pressure lines do not require a water drain, except
for that of the standby static ports.

ADIRS CDU PRESENTATION
SYSTEM SELECTOR
In OFF position, the CDU display is not energized
(Blank Display).
In position 1, 2 or 3 the corresponding system is
selected for data display.
KEYBOARD
The keyboard is used to enter in the selected system
the present position for alignment or Magnetic Heading
if in ATTITUDE mode.
N, S, E, W keys permit position entry.
H allows heading entry in attitude mode.
The green ENTER pushbutton light comes on when either
the NORTH, SOUTH, WEST, EAST, or HEADING has been
selected. When pressed the displayed data is entered
into the Inertial Reference Systems.
The green CLEAR pushbutton light comes on when any key
has been pressed.
When pressed, the displayed data, not yet entered, is
cleared.
ON BAT LIGHT
The amber ON BAT light comes on when one or more Air
Data Inertial Reference Unit are operating on aircraft
batteries.
The ON BAT light comes on for five seconds during the
power up test. ON BAT stays off in case of fast
realignment.
IR LIGHTS
An amber FAULT light comes on, accompanied by ECAM
activation when a fault affects the related Inertial
Reference.
When flashing, attitude and heading may be recovered
in ATT mode.
A white ALIGN light illuminates steady when the related
Inertial Reference is in the alignment phase.
The ALIGN light goes off when alignment has been
completed.
ALIGN light flashes in case of:
- An alignment error
- No Present Position entry within ten minutes
of NAV mode selection.
- Significant difference memorized position at
shutdown and entered position.
MODE ROTARY SELECTOR
The mode rotary selector permits selection of three
modes for each Inertial Reference.
In OFF position, the ADIRU is not energized (ADR and
IR data not available).
NAVIGATION is the normal mode of operation providing
full inertial data to the aircraft systems.
ATTITUDE is a back-up mode, mainly providing attitude
and heading information in case of loss of navigation
capability.
In ATT mode, the magnetic heading must be entered
through the CDU and has to be updated frequently.
