    Which of the following is not a condition that allows an excessive Localizer deviation alert to occur?

    • Low radio altitude

    • Autopilot or Flight Director engaged

    • Incorrect ILS frequency and course selected

    • LOC roil mode engaged

    Correct Answer
    A. Incorrect ILS frequency and course selected
    Explanation
    An excessive Localizer deviation alert occurs when the aircraft deviates significantly from the intended course during an ILS approach. This alert is triggered by various conditions, such as low radio altitude, autopilot or Flight Director engagement, and LOC roll mode engagement. However, selecting an incorrect ILS frequency and course does not directly contribute to the occurrence of this alert.

    • Only during preflight before entry of the ORIGIN.

    Correct Answer
    A. Only on the ground.
    Explanation
    The active navigation database can only be changed on the ground. This means that it cannot be changed during flight or any other time while the aircraft is in the air. The database can only be modified before the flight, during the preflight phase.

    When the ND is in the Plan mode, what is the display orientation?

    • The Top of the display represents Magnetic North.

    • The top of the display represents True North.

    • The top of the display represents the airplane track.

    • The top of the displays represents the airplane heading.

    Correct Answer
    A. The top of the display represents True North.
    Explanation
    In the Plan mode, the display orientation on the ND (Navigation Display) is such that the top of the display represents True North. This means that the map on the ND is aligned with the Earth's geographic north pole. This orientation helps pilots accurately determine their position and navigate along their planned route.

    How often is a complete ADIRU alignment recommended?

    • Every 15 hours

    • Every 24 hours

    • Whenever the total time in the nivigation mode is expected to exceed 15 hours.

    • Whenever the total time in the navigation mode is expected to exceed 24 hours.

    Correct Answer
    A. Whenever the total time in the navigation mode is expected to exceed 24 hours.
    Explanation
    A complete ADIRU alignment is recommended whenever the total time in the navigation mode is expected to exceed 24 hours. This means that after 24 hours of continuous navigation mode operation, it is recommended to perform a complete ADIRU alignment to ensure accurate and reliable navigation data. This alignment helps maintain the accuracy and integrity of the aircraft's navigation system over extended periods of operation.

    The FMC scratchpad message TAKE OFF SPEEDS DELETED does not display for which of the following conditions?

    • A new ZFW is entered on the PERF INIT page.

    • A new FLAPS setting is entered on the TAKEOFF REF page.

    • A new CG value is entered on the TAKEOFF REF page.

    • New runway winds are entered on the TAKEOFF REF page.

    Correct Answer
    A. A new CG value is entered on the TAKEOFF REF page.
    Explanation
    When a new CG value is entered on the TAKEOFF REF page, the FMC scratchpad message "TAKE OFF SPEEDS DELETED" does not display. This means that changing the CG value does not affect the takeoff speeds calculation, and therefore the message is not necessary.

    (WXR & TCAS RANGE ARCS) When are range arcs displayed in the expanded VOR mode?

    • All the time

    • Only at 10, 20, and 40 mile ranges

    • With range scale tics

    • If weather radar or TCAS is selected

    Correct Answer
    A. If weather radar or TCAS is selected
    Explanation
    Range arcs are displayed in the expanded VOR mode if weather radar or TCAS is selected. This means that when the pilot chooses to view the weather radar or TCAS information on the display, the range arcs will be shown as well. The range arcs provide information about the distance from the aircraft to certain points, such as 10, 20, and 40 mile ranges. Therefore, if the pilot wants to see the range arcs, they need to select either weather radar or TCAS.
