    Study Notes

    Flight Deck Equipment and Operation

    • Radar returns on B737-400 displayed on EHSI: Excludes FULL NAV, FULL VOR/ILS, and PLAN modes.
    • FMC position generated from a combination of IRS and radio navigation; serves as the computed position.
    • Best progress information between waypoints from RNAV is shown as ETO (Estimated Time Over).
    • ETOs and ETAs are accurate when actual winds match forecast winds and Mach numbers align.
    • Navigation data in EFIS is sourced from FMC, navigation radios, and Inertial Reference Systems (IRS).
    • FMC databases are read-only, ensuring data integrity and accuracy.
    • Pilots can manually input navigation facilities, reporting points, and airways in the FMC with a maximum of 5 alphanumerics.
    • Visual displays on EADI and EHSI generated by Symbol Generator.
    • FMS database allows pilot to insert navigation data but is read-only during regular operation.
    • Track-line on EHSI indicates aircraft's ground track and accounts for wind influence.

    IRS and FMS Positioning

    • IRS position updates occur on the ground only, providing a stable reference for navigation during flight.
    • FMC position reflects computed values from multiple sources like IRS and GPS, ensuring accuracy.
    • FMS position is least accurate at the Top of Descent (TOD) phase.
    • FMS databases allow pilots to read navigation data during flight without modification.
    • Inertial Navigation System (INS) is a self-contained system that does not rely on external information.

    FMS Operational Modes and Updates

    • Dual FMC systems allow modes of operation: dual, independent, and single.
    • Backup FMS navigation mode activates when there is limited functionality of the FMC due to failure.
    • Gate numbers input is utilized by the FMC to convert gate positions to WGS 84 coordinates for accurate navigation.
    • IRS derives navigational data through built-in sensors, making it self-sufficient in operation.

    Flight Management System Components

    • FMS comprises the command display unit and the flight management computer (FMC).
    • ETA provided by the FMS becomes most accurate with precise ground speed and accurate position inputs.
    • Position fixing in FMC utilizes DME/DME and VOR/DME combinations for navigation accuracy.
    • Initial pre-flight FMC inputs include planned route, aircraft position, and departure runway.

    EFIS and Display Color Codes

    • One dot on EHSI in NAV and EXP NAV modes equals 2 nautical miles.
    • Engaged modes in EFIS are represented in green according to JAR OPS standards.
    • Amber or white/magenta indicate turbulence conditions on EFIS display, enhancing pilot situational awareness.
    • Warnings and system limits highlighted in red; critical for immediate pilot attention.
    • EHSI modes unable to display AWR information include PLAN and FULL VOR/ILS/NAV modes.

    Data Management and Navigation

    • Data relating to performance, flight plans, waypoints, and speeds stored in the FMC across specific databases.
    • Flight Management System configured for optimal database management, read-only for pilots.
    • INS operates independently from all external inputs, providing crucial navigational data for flight operations.
    • Track line on EFIS indicates actual aircraft track over the ground, relevant for navigation adjustments in flight.

    Summary Points

    • Essential understanding of FMC operations, including limitations and applicability of navigation inputs.
    • Familiarity with EFIS displays, their operational modes, and color coding for alerts and indications.
    • Recognition of how positioning systems work together within the cockpit environment for safe navigation and effective flight management.
