ACMS -INTERFACES
General
The ACMS collects data to record and sends reports to many output devices. The MAT and PMATs let you see ACMS data and control ACMS functions.
Data Collection
Airplane systems send data into the left AIMS cabinet input/ output modules (IOMs) on:
*
Flight controls ARINC 629 buses
*
Systems ARINC 629 buses
*
ARINC 429 buses
*
Analog inputs
*
Discrete inputs.
Some airplane system data only goes to the right AIMS cabinet. The data comes from the:
*
Right angle of attack vane
*
Left total air temperature probe, element two.
The data conversion gateway function in the right AIMS cabinet converts this data to ARINC 629. It then transmits the data to the left AIMS cabinet over the right flight controls ARINC 629 bus.
QAR
The QAR sends two discretes to IOM (M003) and IOM (MOO4) in the left AIMS cabinet. The discretes are QAR recorder status and QAR tape low status.
EFFECTIVITY
BEJ ALL
The QAR recorder status discrete shows internal faults.
The tape low discrete shows that the optical disk in the QAR is on the last track.
There are four digital data buses between the QAR and the CPM/Comm in the left AIMS cabinet.
The CPM/Comm sends a synch pulse to the QAR. This sync pulse is in ARINC 717 format.
The CPM/Comm sends ACMF data to the QAR. This ACMF data is in ARINC 717 format.
The CPM/Comm sends control data to the QAR. This control data is in RS422 format. The control data turns on the QAR.
The QAR sends data and status to the CPM/Comm in the left AIMS cabinet. The ACMF monitors the data and status.
Control
The user requests information with the MAT or PMAT. The MAT/PMAT has ACMS menus and display formats. Also, ACMF airline modifiable information loads from the disk drive on the MAT or PMAT.

ACMS -QUICK ACCESS RECORDER
General
The quick access recorder (QAR) records data sent from the ACMF. The QAR has a 3.5 inch 128 MB optical disk. The QAR stores data for 41 hours. The disk is in a cartridge.
Features
There is a 16 character liquid crystal display (LCD). This shows stored data, QAR menus, test results, and messages.
The QAR fail indicator comes on to show memory failures, bus diriver problems, or internal failures.
Open the front door of the QAR to view more features and controls. To open the front door, turn the latch one half turn counter-clockwise on the front of the QAR.
There are two slots for disks. The active slot holds the data disk or program disk. The spare slot holds a spare data disk.
The keyboard has five keys. You use these keys to select data, modes, and tests.
