    1. During a JFS run, JFS accumulators are not charged

    • A.

      True

    • B.

      False

    Correct Answer
    A. True
    Explanation
    During a JFS run, JFS accumulators are not charged. This means that the accumulators, which are used to store and calculate values in a JFS (Job Flow Scheduler) system, do not receive any new inputs or updates during the run. Instead, they retain their previous values and are used for calculations or comparisons as needed. This is true because the purpose of a JFS run is typically to analyze or evaluate a specific set of data or conditions, rather than actively updating or modifying the accumulators.

    What is the normal nozzle position at idle in primary mode?

    • A.

      65-100%

    • B.

      5-30%

    • C.

      70-95%

    • D.

      50-60%

    Correct Answer
    C. 70-95%
    Explanation
    The normal nozzle position at idle in primary mode is typically between 70-95%. This means that the nozzle is partially open, allowing a controlled amount of fuel to flow into the engine during idle. This range ensures that the engine is receiving enough fuel to maintain a stable idle speed without causing it to stall or run too rich.

    Proper oil servicing must be done within how long after shutdown?

    • A.

      15min

    • B.

      30min

    • C.

      45min

    • D.

      75min

    Correct Answer
    B. 30min
    Explanation
    Proper oil servicing must be done within 30 minutes after shutdown. This time frame is crucial to ensure that the oil is still warm and flowing properly, allowing for effective servicing and maintenance. Waiting too long after shutdown can cause the oil to cool down and become thicker, making it more difficult to drain and replace. Additionally, delaying oil servicing can increase the risk of contaminants settling in the oil, potentially leading to engine damage or reduced performance. Therefore, it is important to adhere to the recommended 30-minute time frame for oil servicing after shutdown.

    Correct Answer
    A. Throttle-OFF, ENG MASTER-OFF, repeat
    Explanation
    If a hung star occurs and RPM and FTIT stop at 45-55 percent RPM during start, the correct action to take is to throttle-OFF, ENG MASTER-OFF, and then repeat the start process. This means shutting off the throttle, turning off the engine master switch, and attempting the start again. This is done to address the issue and try to achieve a successful start.

    If engine control light comes on, be sure throttle has been at IDLE for at least _______ seconds before cycling Engine Control switch

    • A.

      10 sec

    • B.

      30 sec

    • C.

      60sec

    • D.

      90 sec

    Correct Answer
    D. 90 sec
    Explanation
    The engine control light may come on due to various reasons, such as a malfunctioning sensor or a problem with the engine system. To ensure accurate readings and proper functioning of the engine control switch, it is important to give the throttle enough time to reach the idle position. Waiting for at least 90 seconds allows the throttle to fully settle at idle, ensuring that the engine control switch is cycled correctly and any potential issues are accurately detected.

    Engine light-off is indicated by a rise in ___________

    • A.

      EGT

    • B.

      FTIT

    • C.

      PGM

    • D.

      LPT

    Correct Answer
    B. FTIT
    Explanation
    Engine light-off is indicated by a rise in FTIT. FTIT stands for Fan Turbine Inlet Temperature, which is the temperature of the air entering the fan turbine section of the engine. When the engine is shut off, there is no more fuel being burned, leading to a decrease in EGT (Exhaust Gas Temperature) and PGM (Pressure and Gas Monitoring) values. However, the FTIT may rise momentarily after engine shutdown due to residual heat in the engine. Therefore, a rise in FTIT indicates engine light-off.

    If fuel low light comes on, ______________ to prevent causing engine damage

    • A.

      Continue and monitor fuel level

    • B.

      Monitor fuel quantity

    • C.

      Reset FUEL PRESS REQ circuit breaker and monitor

    • D.

      Shut down engines

    Correct Answer
    D. Shut down engines
    Explanation
    If the fuel low light comes on, it is important to shut down the engines to prevent causing engine damage. Continuing to operate the engines with low fuel can lead to fuel starvation, which can cause the engine to stall or even suffer from permanent damage. Shutting down the engines allows for a safe inspection of the fuel level and prevents any further complications. Monitoring the fuel quantity or resetting the circuit breaker may not address the immediate issue of low fuel and could potentially worsen the situation.
