SYSTEM DESCRIPTION AND INSTALLATION MANUAL

CAS/Part No.9005000

B. Airplane Personality Module Interface

The Airplane Personality Module (APM) is defined in ARINC Report 607, Attachment 3 -

see Figure 1-9. A serial digital interface between the T

CAS Computer and the APM

allows the APM to be programmed with aircraft and system configurations during the

initial installation of the T

CAS computer. In addition, the serial digital interface allows the

APM to be read during every subsequent power-on to configure the computer for proper

operation. The APM is used to hold/provide information for the T

CAS configuration

database, for example, registration number, aircraft type, equipment installed, et cetera.

Moreover, the APM stores the Aircraft Specific Database (ASDB) which defines the

Input/Output definition for the specific aircraft type and the aircraft climb performance

data to support the TAWS/RWS functionality.

NOTES:

1. It is the responsibility of the installer to ensure the correct ASDB is loaded into

the T

CAS system during aircraft installation. Contact ACSS to determine the

applicable ASDB for a particular installation configuration (i.e., B737-400 with

FMS, GPS, AHRS, etc.).

2. The APM is not applicable for Part Numbers 9005000-10000, -10101, -10202, -

10204, and -11203. These part numbers are configured using pin programming.

3. The DO-160E categories of the APM are the same as listed in Table 1-16.

C. Directional Antenna

The T

CAS directional antenna, Figure 1-10, is a four-element, vertically polarized,

monopole array capable of transmitting in four selectable directions at 1030 MHz and

1090 MHz. The antenna is capable of receiving replies from all directions simultaneously

with bearing information at 1090 MHz and 1030 MHz, using amplitude-ratio monopulse

techniques. The antenna is also capable of transmitting omnidirectionally at 1090 MHz for

transponder transmissions.
