    Study Notes

    Electronic Instrument System (EIS)

    • The EIS is a sophisticated system for aircraft monitoring and control.
    • It consists of two main components: the Electronic Flight Instrument System (EFIS) and the Electronic Centralized Aircraft Monitoring (ECAM) system.

    Electronic Flight Instrument System (EFIS)

    • The EFIS provides the pilots with vital flight information.
    • EFIS displays receive data from the Air Data and Inertial Reference System (ADIRS).
    • The EFIS is used to display flight parameters like airspeed, altitude, and heading on the Primary Flight Display (PFD) while the Navigation Display (ND) shows flight plan and navigation data.

    Electronic Centralized Aircraft Monitoring (ECAM) System

    • The ECAM system provides a centralized display of aircraft systems data, warnings, and faults.
    • It consists of two main displays: the Engine Warning Display (EWD) and the Systems Display (SD).
    • The ECAM system relies on the Flight Warning Computers (FWC), which process data from various aircraft systems.

    Centralized Fault Display System (CFDS)

    • The CFDS stores fault information for future analysis.
    • Information stored in the CFDS can be accessed and printed using the Multipurpose Control and Display Unit (MCDU).

    ELogbook

    • The ELogbook is a laptop computer used to manage and record flight data.

    Digital Flight Data Recording

    • The Solid-State Flight Data Recorder (SSFDR) captures critical flight parameters and system data for crash investigation purposes.

    Aircraft Integrated Data System

    • This system monitors engine condition and aircraft performance.

    Electrical Power System

    • The aircraft's electrical system is powered by two Integrated Drive Generators (IDGs) as the main power source.
    • The ECAM Electrical System page displays real-time data on the aircraft's electrical power systems, including voltage and frequency.

    Air Data / Inertial Reference System (ADIRS)

    • The ADIRS provides accurate information about the aircraft's altitude, airspeed, and heading.
    • The system consists of three ADIRUs (Air Data and Inertial Reference Units) that are controlled by a single ADIRS Mode Selector Unit (MSU).
    • Data from air data sensors, such as pitot probes, static ports, angle of attack sensors, and total air temperature sensors, is collected and transmitted to the ADIRUs.
    • The ADIRUs provide information to the EFIS and the Flight Warning Computer (FWC).

    Landing Aids

    • ILS and Marker System provides guidance during approach and landing phases.
    • The PFD displays the localizer and glide slope information.
    • The aircraft can be guided by either ILS 1 or ILS 2 on the PFD and ND displays.

    Radio Navigation

    • The Navigation computer function in the Flight Management and Guidance Computers (FMGCs) calculates aircraft position.
    • Navigation data can be manually entered or received automatically.
    • In case of FMGC or MCDU failures, the Radio Management Panel (RMP) can be used for backup tuning of navigation receivers.

    Enhanced Ground Proximity Warning System

    • EGPSW alerts pilots of potential ground proximity issues.

    TCAS/T2CAS

    • Terrain and Traffic Avoidance System alerts pilots of potential collisions with other aircraft.

    Radio Altimeter

    • The Radio Altimeter provides height above ground measurement during the initial climb, approach, and landing phases.
    • It is located in the AFT Cargo compartment.

    Auto Flight System (AFS)

    • The AFS is crucial for automatic flight control and includes the following components:
      • Flight Management (FM)
      • Flight Guidance (FG)
      • Flight Augmentation
      • Fatigue Isolation and Detection System (FIDS)
    • The FMGCs carry out the Flight Management (FM) and Flight Guidance (FG) functions, while the Flight Augmentation Computers (FACs) handle flight augmentation and FIDS.

    Flight Management and Guidance Computer (FMGC)

    • The FMGCs manage flight control functions and support the autopilot, flight director, and auto-thrust systems.
    • FMGCs manage flight parameters, such as airspeed and Mach Number.

    Flight Augmentation Computer (FAC)

    • FACs provide supplemental flight control functions such as yaw damper, rudder trim, rudder travel limitation, and flight envelope protection.
    • FIDS is managed by FAC 1.

    Flight Control Unit (FCU)

    • The FCU is located on the front panel and includes the AFS control panel, along with the EFIS control panels.

    Side Sticks

    • The side sticks are locked when the autopilot is engaged.

    Throttle Levers

    • The throttles can be used to manually or automatically control the engines via the auto-thrust system.

    Communication System

    • This system comprises components for communication with ground, cabin crew, and passengers.

    Solid State Cockpit Voice Recorders

    • This system records flight crew conversations and communications.

    CIDS (Cabin Intercommunication Data System)

    • The CIDS is an intercom and communication system for cabin crew, with controls on the Flight Attendant Panel (FAP).

    Gray Water

    • Gray water from lavatories, washbasins, and galley sinks is collected.

    Vacuum Toilet System

    • The vacuum toilet system is activated by a generator above 16,000 ft, eliminating the need for a separate waste tank.

    Service Panel Locations

    • Potable water panel is located on the right-hand side, and the gray water panel is on the left-hand side.

    ATA 28 Fuel System

    • The A/C is equipped with fuel tanks in the fuselage and wings.
