supply align and fail discretes to the MSU. The MSU also
receives an ON DC discrete from the ADIRUs. The ON DC
discrete goes through the IRS master caution unit.
IRS Master Caution Unit Interface
The IRS master caution unit receives fail and ON DC discretes
from the ADIRUs. The IRS master caution unit supplies discrete
outputs to the MSU and to the master caution lights and
annunciators.

General
Each ADIRU receives inputs from these on-side components:
* AOA sensor
* Pitot ADM
* Static ADM.
The AOA sensor gives angle of attack information to the ADIRU.
The ADIRU uses angle of attack to modify pitot and static
values.
The pitot ADM gives the ADIRU total air pressure information.
This is used to calculate airspeed and mach number.
The static ADM gives the ADIRU static air pressure information.
This is used to calculate altitude and airspeed.
These components supply data to both ADIRUs:
* TAT probe
* DEU 1 and DEU 2
* Window and pitot heat module
* Inertial system display unit (ISDU)
* FMC 1.
The TAT probe gives total air temperature to the ADIRUs. The
ADIRUs use TAT to compute TAS and SAT.
DEU 1 and DEU 2 give barometric correction to the ADIRUs. The
ADIRUs use barometric correction to calculate corrected
barometric altitude.
The window and pitot heat module sends a discrete signal to
the ADIRUs when anti ice heat is on. The ADIRUs modify the
input values of these components when anti ice heat is on:
* AOA sensor
* Pitot probe
* TAT probe.
The ISDU gives initial present position data and heading data to
the ADIRUs. The ADIRUs use present position data during the
align mode. Heading data is used during the attitude mode.
The FMC gives the ADIRUs this information:
* Present position
* Heading
* BITE command.
The ADIRUs use present position in the align mode. Heading
data is used in the attitude mode. The BITE command starts the
ADIRU Bite tests.
Multi-mode receiver 1 (MMR 1) and MMR 2 have data buses to
the ADIRUs. The MMRs do not supply any data to the ADIRUs.
The data buses are for future use to send global positioning
system (GPS) information.

General
The left ADIRU supplies inertial reference (IR) data to many
systems and components. IR data goes out on ARINC 429 data
buses. The data on each bus is the same. One data bus goes
from the IR section of the ADIRU to the air data reference (ADR)
section. These are the components and systems that receive IR
data from the left ADIRU:
* Display electronics unit (DEU) 1 and 2
* Radio magnetic indicator (RMI)
* Multi mode receiver (MMR) 1 and MMR 2
* Stall management yaw damper (SMYD) 1 and 2
* Flight control computer (FCC) A and B
* Ground proximity warning computer (GPWC)
* Weather radar receiver transmitter (WXR R/T)
* TCAS computer
* Integrated flight systems accessory unit (IFSAU)
* Inertial system display unit (ISDU)
* Anti skid autobrake control unit (AACU)
* Autothrottle (A/T) computer
* Digital interface unit (DIU)--is Airshow ASINC
* Flight management computer (FMC) 1.
DEU
The DEUs use this IR data from the ADIRUs to show information
on the display units:
* Present position
* Track angle
* Magnetic heading
