DFDMU Theory of Operation Course Online

1. Introduction to DFDMU 
a. Purpose and concept of the Digital Flight Data Management Unit
    (DFDMU).
b. Brief history of the development and requirements for Flight Data
    Recording.
c. Development of the FAA, ED-55 and UK CAA Spec. 18
    requirements.
d. Development of the FAA '91 rule requirement.
e. Functions which the DFDMU performs including a general overview
    of the mandatory and AIDS functions.


2. DFDMU Overview of Operation
a. Brief description of the integral components that comprise a
    DFDMU system.
b. Devices that directly interface with the DFDMU system.
c. Description of the various parameters which the DFDMU may
    acquire, including parameter source, processing by the DFDMU,
    and final disposition.
d. Description of the flight modes in which the DFDMU operates,
    including how each mode affects the functions of the DFDMU
    system's data acquisition, DFDR recording QAR operation,
    and report generation.
3. DFDMU Mandatory Functions
a. Purpose of the DFDMU mandatory section.
b. The circuit cards comprising the mandatory portion of the
    DFDMU including the purpose of each.
c. Operational Theroy, concerning data acquisition and recording
   format for the DFDR.

4. DFDMU Aircraft Integrated Data Systems (AIDS) Functions
a. Purpose of the DFDMU AIDS section. 
b. The circuit cards that comprise the AIDS portion of the DFDMU
    including the purpose of each.
c. Functions the AIDS portion performs including specific
    customer applications.
d. Report generation and distribution within the DEFDARS system
    and systems interfacing.

5. Operator Interface with the DFDMU
a. Cockpit controllers, devices that interface with the DFDMU system. b. Initialization, check out procedures to be performed before flight.
c. Functions which may be performed by the cockpit crew during a
    flight.
d. Demonstration of DFDMU operation on a test station, showing flight
    mode logic, data acquisition, recording report generation, and all
    other operations pertinent to the flight crew in a simulated
    environment.

6. Optical Disk for DFDMU
a. Using the optical disk drive DFDMU. Recording to the optical disk,
    preparing the optical disk, programming and uploading DMP.
b. Optical system description. The Controller Card, Optical Disk Drive,
    Temperature Sensor, and Optical Doghouse.

7. DFDMU Flight Line Test Procedures
a. Documentation helpful for use in troubleshooting an DFDMU
    discrepancy on the Aircraft.
b. Familiarization with the "Fail Annunciator Lamps" on the DFDMU
    and possible scenarios on how they might be set.
c. Familiarization with the DFDMU status readout and the conditions
    they represent.
d. Cockpit indications that would benefit in fault detection and
    isolation.
e. Use of a flight-line tester for troubleshooting an aircraft discrepancy
    to the suspect LRU.
