    Study Notes

    Information Systems (11.21) Learning Objectives

    • Describe the purpose and operation of units and components that enable storage, updating and retrieval of digital aircraft maintenance or operational information (Level 2).

    Aeroplane Digital Information Systems

    • Information systems are used in modern aircraft to communicate within the aircraft and between ground stations using data links.
    • The core objective is a cost-effective system for flight operations, maintenance and passengers.
    • These systems manage data links and communication messages, controlled automatically or manually.
    • Cockpit Information Systems (CIS) include Air Traffic and Information Management System (ATIMS), Air Traffic Control (ATC), Airline Information Services-Airline Operational Control (AOC) applications and Future Air Navigation System (FANS).
    • Maintenance information systems exist.

    ATIMS Communication

    • ATIMS extensively uses data communications between aircraft and the airline, and between aircraft and Air Traffic Control (ATC).
    • Data exchange reports or specific messages between aircraft and ground centres, including Controller-Pilot Data Link Communications (CPDLC) (HF voice support), to reduce operational costs and increase flexibility.
    • Communication is via data link or VHF Data Radio (VDR)/HF Data Radio (HFDR)/SATCOM (satellite communication).
    • Aircraft Communication Addressing and Reporting System (ACARS) dispatches messages from ground.
    • VHF and HF voice communications provide backup.
    • Automatic Dependant Surveillance (ADS) automatically relays position and other relevant data to ATC.

    ATIMS Components

    • Air Traffic Service Unit (ATSU): Receives, routes, and acquires ground messages, from peripherals and sends to ground.
    • Data Control and Display Unit (DCDU): Dedicated to ATC applications, displays messages from ATC ground centre and sends responses.
    • Multifunction Control Display Unit (MCDU): Used by ATC operators.
    • ATC MSG Illuminated Push-Button Switches: Provides visual alerts for ATC message reception, allowing cancellation of alerts. Some aircraft use aural alerts as well.
    • ATSU Reset Switch: Resets the Air Traffic Service Unit (ATSU) when required.

    ATIMS Interfaces

    • The ATSU is connected to Central Maintenance Computers (CMCs) for maintenance purposes.
    • The system's Built-In Test Equipment (BITE) is ensured by the ATSU.
    • Data messages are exchanged between the ATSU and CMCs regarding application status, datalink availability, part numbers and software numbers.
    • Aircraft configuration parameters and registration numbers (ARN), flight numbers are acquired from the CMC to support ground communication.

    FMGEC/ATIMS Interface

    • The FMGEC (Flight Management Guidance Envelope Computer) interfaces with the ATSU to gather flight-management information (e.g., airports, flight numbers, fuel).
    • ATSU acts as a router for such data exchanges, supporting Airline Operational Control (AOC) remote application.

    Multi-Purpose Control and Display Units (MCDUs)

    • MCDUs are used for maintenance and application purposes by the ATIMS.
    • They provide aircrew access to specific ATC pages to enter parameters and justify responses for messages.

    Other ATIMS Interfaces

    • The system interfaces with VHF Data Radio (VHR), HF Data Radio (HFDR), and Satellite Data Unit (SDU) via the Radio Management Panel (RMP).
    • Flight Warning System (FWC): Generates warnings based on flight phases and priorities.
    • Aircraft Condition Monitoring System (ACMS): Reports engine (APU) status to the ATSU for downlink reports.
    • Clock: Provides date and time to the ATSU.
    • Data Loading System: Uploads application software and databases, potentially assisted by a portable data loader or Multi-Purpose Disk Drive Unit (MDDU).
    • Printer: Status of the printer is monitored.
    • Landing Gear: The ATSU's status of aircraft on the ground or in flight is reported to ATSU using the Landing Gear Control Interface Unit (LGCIU).

    Cabin Terminals

    • Consist of the Passenger Flight Information System (PFIS) and Cabin Passenger Management System (CPMS).
    • These systems exchange ARINC 619 messages using the ATSU as an ACARS router.

    • The ATIMS includes air traffic control and airline operational control functions.
    • Air Traffic Control functions include CPDLC, ADS and AFN applications.
    • Airline Operational Control applications include remote and hosted AOC applications, integrated with FMGECs, CMCs, ACMS, and cabin management terminals (peripherals).
    • Aim is to establish a dialog between ATC controllers and flight crews using datalink communication instead of voice communication.
    • Uses message elements matching existing ATC procedures.
    • Messages are displayed on the Data Control and Display Unit (DCDU).

    Automatic Dependent Surveillance (ADS) Application

    • Provides ATC ground centre with aircraft surveillance, positions, and identification via an ADS agreement, including periodic, event-based, or on-demand contracts.
