B. TAWS/RWS Data Configuration
(1) ASDB
The ASDB is a field loadable database that customizes the T
2
CAS operation for a
specific aircraft. The ASDB defines the Input/Output definition for the specific aircraft
type, the aircraft climb performance data to support of the TAWS functionality, and
the windshear algorithm coefficient data. The ASDB file is produced with a unique
part number and can be uploaded to the APM via the RS--232 port or from a
Compact Flash card.
The ASDB I/O Database contains specific information needed to perform the I/O
functionality for the specific aircraft type. The I/O tables define the following types of
information for p rocessing system inputs and outputs:
• Physical mapping between external systems and T
2
CAS inputs and outputs.
Example, GPS #1 is connected to ARINC 429 Input Bus #5.
