LINEAR ACCELEROMETER
IDENTIFICATION
FIN: 6TU
LOCATION
ZONE: 145
COMPONENT DESCRIPTION
The acceleration force moves a pendulum in the sensing
mechanism. A proximiter senses the movement which
generates a signal proportional in amplitude to the
movement.
The Linear Accelerometer (LA) is located in the center
part of the fuselage, below the cabin floor panel and
close to the aircraft Center of Gravity (CG).

QAR/OQAR
IDENTIFICATION
FIN: 3TU
LOCATION
ZONE: 127, 87VU
COMPONENT DESCRIPTION
The Quick Access Recorder (QAR) is an optional
component of the Digital Flight Data Recording System
(DFDRS).
There are several vendors and two different storage
media:
- Either a cassette (50 hour magnetic tape),
- or an optical disk. The recorder is then called
Optical QAR (OQAR).
The OQAR, described in this topic, is provided as an
example.
A door, incorporated in the front panel of the OQAR,
gives access to the optical disk and controls.
The following indicators are located above the door:
- A 16 character alphanumeric display shows
various menus and messages.
- A fail light indicates an OQAR failure.
- A front connector, located below the door,
enables equipment tests to be performed.

AIDS: AIDS PRESENTATION
GENERAL
The Aircraft Integrated Data System (AIDS) main
functions are to perform engine condition, APU
condition and aircraft performance monitoring as well
as trouble shooting assistance.
The AIDS consists of:
- a Data Management Unit (DMU) including a Smart
AIDS Recorder (SAR) and an optional Personal
Computer Memory Card International Association
(PCMCIA) interface,
- an optional Digital AIDS Recorder (DAR),
- an optional "on-ground" equipment called Ground
Support Equipment (GSE).
DMU
The Data Management Unit (DMU) is the heart of the
AIDS.
This avionics computer assumes, as a minimum, the
following basic functions:
- Collection and processing of various aircraft
parameters.
- Generation of various reports according to
defined conditions.
These reports are stored in a non-volatile
Solid State Mass Memory (SSMM) of the DMU.
