Mixed Deck — All EAWS Topics Flashcards

What is the primary purpose of an Individual Material Readiness List (IMRL)?

Answer: To specify the types and quantities of Support Equipment (SE) required for an activity to perform its assigned maintenance functions.

The Individual Material Readiness List (IMRL) is a consolidated allowance list that specifies all items of Support Equipment (SE) and specialized tools required for an aviation maintenance activity to perform its assigned duties. It ensures the unit has the correct ground support capabilities.

According to the EAWS PQS, which of the following are the three primary objectives of first aid?

Answer: Prevent further injury, prevent infection, and prevent the loss of life

The fundamental goals of providing first aid are to keep the victim's condition from worsening, protect them from contamination, and take necessary steps to save their life. These are often summarized as preventing further injury, infection, and loss of life.

An aircraft's landing gear fails to retract after takeoff. The hydraulic pressure gauge indicates a rapid drop to zero, and a visual inspection from the cabin reveals fluid streaming from the right main gear wheel well. Which of the following components has most likely failed?

Answer: An actuating cylinder seal

The scenario describes a localized leak associated with a specific component's operation (landing gear). An actuating cylinder is the component that converts hydraulic pressure into the mechanical motion to move the gear. A failure of its seal would result in a significant fluid leak at that location when the system is pressurized, leading to a loss of system pressure as described. A reservoir failure would likely not be localized to the wheel well, a pump failure would cause pressure loss without a massive external leak, and a relief valve failure would typically vent fluid overboard at the valve's location, not necessarily in the wheel well.

What color smoke signal is internationally recognized as a distress signal?

Answer: Orange

Orange smoke is the internationally recognized distress color used by downed aircrews and shipwreck survivors to signal their location to rescuers.

An Aviation Ordnanceman is preparing a presentation on naval aviation milestones. They need to identify the first ship specifically designed and constructed from the keel up as an aircraft carrier for the U.S. Navy. Which ship should they name?

Answer: USS Ranger (CV-4)

While the USS Langley was the first aircraft carrier, it was a conversion. The USS Ranger (CV-4), whose keel was laid in 1931 and commissioned in 1934, was the first ship in the U.S. Navy to be designed and built from the hull up as an aircraft carrier.

What does 'HEED' stand for in aviation survival equipment?

Answer: Helicopter Emergency Egress Device

HEED (Helicopter Emergency Egress Device) is a small self-contained underwater breathing apparatus that provides breathable air during helicopter underwater escape.

The USS Langley (CV-1), the first aircraft carrier of the U.S. Navy, was converted from what type of ship?

Answer: A collier

The USS Langley (CV-1) was commissioned in March 1922 after being converted from the collier USS Jupiter (AC-3). This conversion marked the birth of the U.S. Navy's carrier fleet.

What is the military UHF guard (emergency) frequency monitored by all military aircraft and installations?

Answer: 243.0 MHz

243.0 MHz is the military UHF emergency guard frequency, exactly double the civilian VHF guard frequency of 121.5 MHz.

What is the primary operational advantage of an Inertial Navigation System (INS) over radio-based navigation aids?

Answer: Operation without any external signals or references

INS uses onboard accelerometers and gyroscopes to dead-reckon position from a known starting point, requiring no external transmissions and making it jam-proof.

How does the Global Positioning System (GPS) determine an aircraft's position?

Answer: By calculating position from timing signals received from orbiting satellites

GPS receivers compute precise position, velocity, and time by measuring the arrival time of signals from a constellation of orbiting satellites.

The Monthly Maintenance Plan (MMP) is a key management tool used by aviation maintenance activities. Which of the following best describes its purpose?

Answer: To provide a schedule for predictable maintenance workload, such as inspections and training.

The Monthly Maintenance Plan (MMP) is used to provide scheduled control of predictable maintenance workloads. It outlines planned inspections, training, and other scheduled events for the upcoming month.

A plane director needs to signal the pilot to engage the aircraft's brakes. According to NAVAIR 00-80T-113, what is the correct hand signal for this command?

Answer: Extend an arm horizontally in front of the body with fingers extended, then clench the hand into a fist.

The correct signal for 'set brakes' is to extend the arm and hand horizontally in front of the face or body with fingers extended, and then clench the hand into a fist, simulating the application of pressure.

A work center generates rags contaminated with oil and solvents during daily maintenance. To prevent a fire hazard from spontaneous combustion, what is the correct disposal method for these rags?

Answer: Placing them in a designated, approved, and properly labeled fire-safe metal container with a lid.

Rags soaked with flammable or combustible materials like oils and solvents must be placed in a designated, fire-safe metal container with a self-closing lid. This practice limits oxygen, dissipates heat, and contains any potential fire, mitigating the risk of spontaneous combustion. These containers must be emptied daily.

What is a 'misfire' in ordnance terminology?

Answer: A weapon that fails to fire after being triggered

A misfire is a complete failure of a weapon to fire after the trigger or firing mechanism has been actuated.

Which of the following best describes a primary objective of the Navy's Hazardous Material Control and Management (HMC&M) program?

Answer: To minimize the quantity of hazardous materials used and stored by seeking less hazardous substitutes.

A key goal of the HMC&M program is source reduction, which involves minimizing the introduction of hazardous materials into the Navy system. This is achieved by controlling inventory, seeking less hazardous or non-hazardous substitutes, and safely managing the lifecycle of required chemicals to reduce risks to personnel and the environment.

How can a sailor keep their EAWS qualification current?

Answer: By attending mandatory refresher training and staying updated with changes in aviation operations.

To keep their EAWS qualification current, sailors must actively participate in mandatory refresher training and stay informed about any changes or advancements in aviation operations, systems, and safety regulations. This continuous learning ensures their knowledge and skills remain relevant and up-to-date, reflecting the dynamic nature of naval aviation.

What unique capability does the Automatic Carrier Landing System (ACLS) provide to carrier-based aircraft?

Answer: Fully automatic approach and landing in zero-visibility conditions

ACLS uses a shipboard radar and data-link to provide fully automatic approach and landing guidance, allowing recovery in zero-zero visibility conditions.

What is the purpose of 'downloading' ordnance from an aircraft?

Answer: Removing weapons from the aircraft after a mission

Downloading refers to the process of removing weapons and ordnance from an aircraft, typically after a mission or when ordnance is no longer needed.

IFF Mode 3/A is used primarily for which purpose?

Answer: Civil and military ATC identification using a 4-digit code

Mode 3/A is a shared civil/military mode in which aircraft squawk a 4-digit octal code assigned by ATC for identification on secondary surveillance radar.

Why is the EAWS qualification valued within the aviation community?

Answer: It reflects a sailor’s broad knowledge and capability in supporting complex aviation operations.

The EAWS qualification is highly valued within the aviation community because it demonstrates that a sailor has the necessary knowledge and practical skills to support and maintain aviation operations, contributing to mission success and safety.
