    Study Notes

    Flares and Munitions

    • F-15 and F-16 aircraft utilize MJU-12 flare magazines.
    • A complete cluster bomb unit (CBU) comprises small submunitions and a dispenser.
    • A dummy round is a standard round with primer and propellant removed.

    Gun Systems and Ammunition

    • Rotary-based gun systems achieve higher rates of fire as all firing cycle steps occur simultaneously.
    • Typical operating range for time fuzes is between 5 to 92 seconds.
    • The GAU-8 30mm gun firing cycle involves a firing pin spring activating when the cocking pin is released.

    Aircraft Systems and Components

    • AN/ALE-50 decoys can be deployed by F-16 and B-1 aircraft.
    • The AGM-65 missile is secured on the LAU-88 launcher by a shear pin.
    • All GBU-12 models utilize MK-82 bombs as their warhead.

    Corrosion Control and Equipment Handling

    • Navel mine casings are painted gold for identification.
    • Aluminum's oxide film enhances its resistance to mild corrosive conditions.
    • Ammunition should be shielded from sunlight to avoid heat-induced ballistic impact.

    Ground Equipment and Safety Protocols

    • Corrosion control management prioritizes detection and treatment at the earliest stage.
    • During concurrent servicing, a concurrent servicing supervisor is unnecessary if fueling is not conducted.
    • Air-cooled, 25.2-horsepower diesel engines power MHU-83 lift trucks.

    Weight and Capacity Specifications

    • The MJ-1 lift truck with aluminum rollers has a lifting capacity of 3,000 pounds.
    • The maximum lift height of the mechanical ram assembly (MRA) is 83 inches.
    • MHU-110/M trailers can accommodate 24 trolleys and 48 chocks for various munitions.

    Operational Procedures

    • Each operation of the A/M32A-86 generator set requires checks on three instrument/control panels.
    • Before connecting high-pressure service hoses, ensure the system is not pressurized.
    • Use "Y" stands to temporarily support munitions, whereas load binders secure loads to the table.

    Safe Loading Practices

    • A/M32A-95 fuel tanks should not exceed half full due to fuel expansion properties.
    • The parking brake on the MHU-83 is set using a locking valve and service brake pedal.
    • The FL-1D floodlight needs a 10-15 minute cooldown period before restarting.

    Miscellaneous Facts

    • High-explosive bombs are categorized based on their kill mechanism or designed use.
    • Built-in test units in rail launchers monitor proper voltage tolerances.
    • AIM-9 L/M missile guidance canards are controlled electrically, and pitch valves on bomb racks are adjusted manually.

    Towing and Aircraft Maintenance

    • A tow bar's travel for MHU-204/M and MHU-196/M lift trailers is limited to 45 degrees.
    • The air conditioner A/M32C-10 should be positioned 15-30 feet away from aircraft for optimal performance.
    • During loading, serviceability of munitions loading stations is evaluated in the aircraft preparation step.

    Environmental Considerations

    • General-purpose bombs typically detonate within two to four minutes after exposure to flames.
    • Operators must verify fluid levels in lubrication systems via sight glasses during maintenance checks.
    • Avoid exceeding 30 psi during cleaning equipment or work areas to maintain safety.

    Emergency Protocols

    • Flush eyes with water and seek medical attention if hydraulic fluid contacts them during equipment operations.
    • Documentation of bomb markings should include lot numbers and serial numbers in case of malfunctions.
    • Safety measures require two operators present during the use of the -10 air conditioner for safe operation.

    Instrumentation and Testing

    • Fault isolation systems utilize built-in tests to identify issues down to a subsystem level.
    • The M240 machine gun cycle of operation consists of eight distinct steps.
    • The mechanical ram assembly (MRA) has a lifting capacity of 5,000 pounds, ensuring heavy-duty operation capabilities.
