1.0 PURPOSE
The purpose of this document is to provide the instructions and procedures necessary to insure
proper operation of a Honeywell Flight Data Acquisition Management System (FDAMS) control,
display and data output to the Multi-Input Interactive Display Unit (MIDU), PTA-45B Data
Printer, and the Penny and Giles optical Quick Access Recorder (QAR). The Honeywell FDAMS
unit consists of a Digital Flight Data Acquisition Unit (DFDAU) and an Aircraft Condition
Monitoring System (ACMS) in a single 6 MCU box. This document provides procedures that will
verify the proper communication between the ACMS and MIDU, Data Printer and QAR. These
procedures have been defined to support a revision to the Honeywell Supplemental Type
Certification ST00939SE and are not required for subsequent installations using the STC.
2.0 GENERAL
The procedures in this document assume that a complete installation checkout has been
accomplished per Honeywell Engineering Order 756-0074-106. It is also assumed that the
person(s) performing the test has a working knowledge of the FDAMS ACMS as installed in this
aircraft. It is up to the discretion of the person(s) performing the tests as to what order is the most
logical to perform the tests. Procedures contained in the aircraft maintenance manual may be
substituted for any portion of this document, as appropriate.
