Re:
B767 Flyht, AFIRS (Automated Flight Information Reporting System)
Familiarization Training
A. Air Transport International is actively modifying the B767 aircraft that it operates with the
Flyht AFIRS system, certified under STC ST02523NY. Operating and Testing of the
AFIRS Global Messaging System must be performed by personnel familiar with the
aircraft and systems.
B. Following is a comprehensive outline of the AFIRS system. This information is covered in
more detail in the ATI 767 Supplemental Maintenance Manual, Section 23.01, and
includes the following detailed information on this system:
1. Description.
2. Operation.
3. Troubleshooting.
4. Maintenance practices.
5. Removal/Installation.
6. Operational Tests.
7. Functional Test.
C. The ATI 767 Sup. MM section also provides a general description with references to the
applicable CMM/OHM supplements concerning AFIRS Global Voice and Messaging
systems and also provides reference to the AFIRS Antenna detailed inspection job card.
For the purpose of this familiarization training, it is not necessary to read these additional
references; however an awareness of this material for future requirement is considered
essential.
FLYHT AFIRS SYSTEM (STC ST02523NY) (Ref. ATI 767 Supplemental
Maintenance Manual, Section 23.01)
NOTE: The AFIRS System is a non-essential, non-critical avionics system. The system
is not required for operation of the aircraft.
NOTE: This section contains excerpts from Flyht AFIRS System MM Supplement. For the
complete MM Supplement, refer to the ATI issued Boeing 767 Component
Maintenance Manual (CMM/OHM) (D634T101) disc.

1. Description
A. AFIRS Unit
(1) The AFIRS (Automated Flight Information Reporting System) is the avionics unit that
collects data automatically on board an aircraft. Data summary files are transmitted
through an onboard satellite modem for immediate analysis and generation of
various reports. The complete raw data is stored on the built-in, removable,
Compact Flash memory card, herein referred to as the flash (memory) card. Thus,
the AFIRS unit is a Quick Access Recorder (QAR). The raw data is periodically
uploaded to the UpTime Flight Data Center.
(2) The front panel has an access door that allows access to the internal flash memory
card and two LED lights. An external maintenance port is also located on the front
panel.
(3) The AFIRS rear connector is an ARINC 404B connector plug and provides the
following connectivity:
(a) 28 VDC Power and ground connection
(b) AFIRS Indicator Panel Interface
(c) ARINC 573/717 and ARINC 429 inputs
(d) RS-422 interfaces
(e) Discrete sensor inputs
(f) Discrete outputs
(g) Iridium antenna connection
(h) GPS antenna connection
(i) AFIRS Keypad interface
(j) 2 wire phone connection

(4) Each AFIRS unit is identified by a data placard located on the front panel of the
AFIRS unit. The data placard contains the part number of the unit as well as a
unique serial number. The configuration, modification status and firmware
version are also on the placard. The configuration, in general, refers to a
unique customer and/or aircraft set-up for the unit. The modification status, in
general, refers to hardware upgrades to the unit.
B. AFIRS Antenna - The AFIRS Antenna is a Sensor Systems S67-1575-163 low
profile dual-band active antenna which provides GPS input to the AFIRS unit and
also provides continues Tx/Rx Iridium band coverage. The antenna is installed
between STA 478 and STA 522 on the top of the fuselage crown between STR 1L
and STR 1R.
C. AFIRS Indicator Panel - The AFIRS Indicator Panel is located in the flight
compartment P8 center pedestal (preferred location) or in the P5 overhead panel
(alternate location).
D. Aircraft Identification Enclosure Assembly - The Aircraft Identification Enclosure
Assembly (ACID) is installed on the upper level of the AFIRS mounting tray located
on shelf E2-2 of the avionics rack in the aircraft forward equipment center. The
Aircraft Identification Enclosure Assembly provides a unique aircraft identified to
the AFIRS unit. It is pre-programmed and is not operator maintainable.
