    The correct answer is mission-essential system functions. The communications-electronics (C-E) mean time between critical failure (MTBCF) specifically measures the average operating time between system failures of mission-essential system functions. This means that it focuses on the functions that are crucial for the mission's success and reliability. It does not include ground-based system functions, aircraft-related system functions, or all base support system functions, as these may not necessarily be directly related to the mission's essential operations.

    • Isochronal

    • Periodic

    • Phased

    • Depot

    Correct Answer
    A. Phased
    Explanation
    The objective of the phased inspection concept is to minimize the length of time that an aircraft is out of commission due to a scheduled inspection. This means that the phased inspection concept is designed to efficiently and effectively carry out inspections on an aircraft while minimizing the impact on its operational availability.

    (605) All aircraft, no matter what inspection concept applies, are required to have how many calendar inspections?

    • One

    • Two

    • Three

    • Four

    Correct Answer
    A. Two
    Explanation
    All aircraft, regardless of the inspection concept applied, are required to have two calendar inspections. This means that there are specific intervals of time in which these inspections must be conducted to ensure the safety and proper functioning of the aircraft. These inspections are necessary to identify any potential issues or maintenance needs that may arise over time.

    (612) What mission capability status code is the sum of not mission capable supply (NMCS) and not mission capable both (NMCB) and reflects total not mission capable (NMC) aircraft limitations due to supply?

    • Fully mission capable (FMC).

    • Partial mission capable (PMC).

    • Not mission capable both (NMCB).

    • Total not mission capable supply (TNMCS).

    Correct Answer
    A. Total not mission capable supply (TNMCS).
    Explanation
    The correct answer is Total not mission capable supply (TNMCS). This mission capability status code reflects the total number of aircraft that are not mission capable due to supply issues. It includes both not mission capable supply (NMCS) and not mission capable both (NMCB) aircraft limitations. This code indicates that the aircraft cannot perform its mission due to supply-related problems.

    (615) Which rate is used to measure speed of repair and equipment maintainability?

    • Fix rate

    • Break rate

    • Utilization rate

    • Mission capable rate

    Correct Answer
    A. Fix rate
    Explanation
    The fix rate is used to measure the speed of repair and equipment maintainability. It refers to the rate at which repairs are made to equipment or machinery when they break or malfunction. A higher fix rate indicates that repairs are being done quickly and efficiently, resulting in less downtime and improved equipment availability.

    (615) The total abort rate is a combination of

    • Air and ground abort.

    • Air abort, late takeoff, and ground abort.

    • Air abort, total deviations, and ground abort.

    • Air abort, ground abort, and maintenance cancellation.

    Correct Answer
    A. Air and ground abort.
    Explanation
    The correct answer is "air and ground abort." This means that the total abort rate includes both air aborts and ground aborts. Air abort refers to a situation where an aircraft has to abort its takeoff or landing due to a technical issue or safety concern. Ground abort, on the other hand, refers to an abort that occurs before the aircraft even takes off, such as when there is a problem with the aircraft on the ground. By including both air and ground aborts in the total abort rate, a comprehensive picture of the number of aborts can be obtained.

    (621) The communications-electronics (C-E) mean repair time (MRT) starts when the technician

    • Leaves his workcenter.

    • Arrives at the equipment.

    • Completes troubleshooting.

    • Receives notification of a workorder.

    Correct Answer
    A. Arrives at the equipment.
    Explanation
    The correct answer is "arrives at the equipment." This means that the mean repair time (MRT) starts when the technician reaches the equipment that needs to be repaired. This makes sense because the technician cannot begin the repair process until they are physically present at the equipment. The MRT does not include the time it takes for the technician to travel to the equipment or receive notification of a workorder. The MRT specifically focuses on the time it takes for the technician to repair the equipment once they have arrived at the location.
