    Vertical Path Parameters (FPA, V/B, V/S) display which of the following parameters related to the present vertical path:

    • FPA-actual flight path angle based on flight plan ground speed and vertical speed.

    • V/B vertical bearing direct from present position of the WPT/ALT line.

    • V/S-the required vertical speed to fly the displayed FPA.

    • Blank if there is no entry on the FPA/VS line.

    Correct Answer
    A. V/B vertical bearing direct from present position of the WPT/ALT line.
    Explanation
    The correct answer is V/B, which stands for vertical bearing direct from the present position of the WPT/ALT line. This parameter indicates the angle between the vertical path and the direction from the current position to the desired waypoint or altitude. It helps the pilot in maintaining the correct vertical navigation by providing information on the alignment of the aircraft with the desired path.

    When airplane gross weight is not available from the EMC, the Approach Ref page will be:

    • Flashing.

    • Blank.

    • Box prompts.

    • INVALID".

    Correct Answer
    A. Box prompts.
    Explanation
    When the airplane gross weight is not available from the EMC (Electronic Maintenance Computer), the Approach Ref page will display box prompts. This means that the system is prompting the user to manually enter the necessary gross weight information in order to calculate the approach reference speeds and other relevant data. This ensures that the aircraft's performance calculations are accurate and tailored to its specific weight.

    What information is available with the IRS mode selector in ATT?

    • Only attitude information.

    • Only heading information.

    • Only attitude and heading information.

    • Only altitude information.

    Correct Answer
    A. Only attitude and heading information.
    Explanation
    The correct answer is "Only attitude and heading information." The IRS mode selector in ATT provides information related to both attitude and heading. This means that it provides data about the aircraft's orientation (attitude) and the direction it is pointing (heading). It does not provide information about altitude or any other parameters.

    During the PRELIMINARY COCKPIT PREPARATION, the IRS Mode Selectors are positioned to:

    • ALIGN.

    • NAV.

    • ATT.

    • ON.

    Correct Answer
    A. NAV.
    Explanation
    During the preliminary cockpit preparation, the IRS (Inertial Reference System) Mode Selectors are positioned to "NAV" which stands for Navigation. This means that the system is set to the navigation mode, allowing the IRS to provide accurate position and navigation information to the aircraft. The NAV mode is crucial for the aircraft to determine its position, track, and other important navigation parameters during the flight.

    When the IRS's are operating in the normal navigation mode they provide:

    • Attitude and true and magnetic heading.

    • Acceleration, vertical speed, and ground speed.

    • Track, present position, and wind data.

    • All of the above

    Correct Answer
    A. All of the above
    Explanation
    When the IRS (Inertial Reference System) is operating in the normal navigation mode, it provides attitude and true and magnetic heading, acceleration, vertical speed, and ground speed, as well as track, present position, and wind data. In other words, all of the given options are correct. The IRS is a navigation system used in aircraft to determine its position, attitude, and other important parameters for navigation purposes.

    A fast realignment should be complete in:

    • 30 seconds.

    • 1 minute.

    • 5 minutes.

    • 10 minutes.

    Correct Answer
    A. 30 seconds.
    Explanation
    A fast realignment should be complete in 30 seconds because it is designed to be a quick and efficient process. Realignment typically refers to adjusting or repositioning something, and in this context, it is likely referring to realigning a piece of equipment or machinery. The fact that it should be done in a short timeframe suggests that it is a simple and routine task that can be accomplished swiftly.

    When does an IRS automatically enter the navigation mode?

    • The mode selector is moved from OFF to ALIGN and 10 minutes have elapsed.

    • The mode selector is in NAV, present position entered, and alignment is complete.

    • The mode selector is moved from ATT to NAV and alignment is complete.

    • When all of the information is available for normal operations in the ALIGN mode.

    Correct Answer
    A. The mode selector is in NAV, present position entered, and alignment is complete.

    Which of the following is not a major component of the inertial system?

    • Air data inertial reference units (ADIRU).

    • Inertial system display unit (ISDU).

    • Instrument Display Unit (IDU) transfer switch.

    • Mode select unit (MSU)

    Correct Answer
    A. Instrument Display Unit (IDU) transfer switch.
    Explanation
    The inertial system is a navigation system that uses inertial sensors to provide accurate position, velocity, and attitude information. The major components of the inertial system include the Air data inertial reference units (ADIRU), which combine air data and inertial data, the Inertial system display unit (ISDU), which displays the information from the ADIRU, and the Mode select unit (MSU), which allows the pilot to select different modes of operation. The Instrument Display Unit (IDU) transfer switch is not a major component of the inertial system, as it is not directly involved in the navigation function but rather in the transfer of information between different instrument display units.
