AFIRS 228™ Automated Flight Information & Reporting System

Access ACARS over Iridium and Cockpit SATCOM Voice via the Global Iridium Network

L3’s AFIRS 228 Iridium Global Communications System provides aircraft crew with reliable, secure voice and data services for ATC, AOC and AAC communications, using Iridium’s global satellite network. The automated flight information and reporting system, which enables Aircraft Communications Addressing and Reporting System (ACARS) operations, is available today.

AFIRS 228 Key Features:

  • MCDU Priority Voice Dialing
  • Integrated cockpit audio
  • Long-range FANS & CPDLC

AFIRS 228 enables Long-range FANS & CPDLC

The AFIRS 228, designed for demanding 21st century communications needs, enables long-range Future Air Navigation System (FANS) and Controller-to-Pilot Data Link Communications (CPDLC) using the Aircraft Communications Addressing and Reporting System (ACARS) network for traffic controller-to-pilot messaging.

Two Iridium transceivers for global connection, safety data link services

The AFIRS 228 Satellite Data Unit (SDU) has two Iridium transceivers. One transceiver provides global voice and data communications using standard SATCOM cockpit controls from the audio control panel and the MCDU. The second modem is dedicated to safety data link services using standard ACARS and FANS message sets (e.g., CPDLC and ADS-C). The single Iridium antenna is a low-profile, passive device mounted directly to the aircraft fuselage. This antenna connects to the Iridium SDU through a coaxial cable.

Telecom functions integrated into the cockpit audio system

The AFIRS 228 SDU includes telecom functions integrated into the cockpit audio system for the flight crew and also through conventional two-wire “tip and ring” telephony devices. A separate SDU Configuration Module (SCM) contains the Iridium ATS or non-ATS SIM Card, system configuration information and user-stored information (e.g., phone lists) to simplify the process if a unit needs to be replaced.
