This suggests that the disc is specifically designed for this purpose and is likely to be durable and resistant to the conditions present in a fuel tank environment. The use of aluminum also indicates that it is lightweight and corrosion-resistant, making it a suitable material for this application.

The simplest and most expedient method of fuel resupply is using the same source of supply as the host airfield. This means that the aircraft can refuel directly from the fuel source that is already available at the airfield, without the need for additional transportation or logistics. This method is efficient and convenient, as it eliminates the need for extra steps or processes in the fuel resupply chain.

The ABFDS can carry a maximum of 30,000 gallons per sortie.

The correct answer is RUN and IDLE. These are the two positions of the throttle switch located on the R-18 pumping unit's handheld remote. The throttle switch allows the operator to control the speed of the pumping unit. The RUN position is used when the unit needs to operate at full speed, while the IDLE position is used when the unit needs to operate at a lower speed or when it is not actively pumping.

When preparing the R–20 filter separator unit for shipment, it is necessary to drain all components except for the surge suppressors. This is because surge suppressors are designed to protect electrical equipment from voltage spikes and surges, and they do not contain any liquids or gases that need to be drained. Therefore, it is not necessary to drain the surge suppressors before shipping the unit.

The correct answer is Expeditionary LRS at the forward location. When a MRSP kit is transferred, the temporary accountability for the kit rests with the Expeditionary LRS at the forward location. This means that they are responsible for the kit until it reaches its final destination or is transferred to another organization. The using organization, accountable officer, and home unit LRS customer service element are not responsible for the temporary accountability of the kit.

Prior to shipping the R-22, it is important to thoroughly clean the unit, drain all fuel from the piping, and disconnect and drain all hose assemblies. However, placing the unit in the low mobility position is not necessary before shipping. This suggests that the unit does not need to be prepared for easy movement or transportation, as it will not be moved or transported in the low mobility position.

Each R-20 multi-aircraft servicing platform is equipped with 1,500 feet of communication wire.

Bladder operations require a stable and level surface to ensure the safety and accuracy of the procedure. A site with a slope greater than 3° would make it difficult to maintain stability and could potentially lead to complications during the operation. Therefore, a site with less than 3° slope is preferred for bladder operations.

The correct answer is a reading of 16 pounds per square inch, differential (psid) on the differential pressure (DP) gauge. This is because a reading of 16 psid on the DP gauge does not indicate a high differential pressure, which is typically the main reason for replacing filter elements. The other conditions mentioned, such as a reading of 22 psid on the DP gauge, elements that have been in use for 36 months, and questionable filter separator vessel performance, all suggest a need for replacement of filter elements.

The PMU-27M is equipped with a priming valve to aid in priming. This valve allows for the controlled release of fluid or air to fill the system and remove any air pockets or blockages. By using the valve, the priming process becomes more efficient and ensures that the system is properly primed before operation. The valve also allows for easy maintenance and troubleshooting, as it can be closed to isolate the system if needed.

A temporary movement of a MRSP kit from home station to another location for a period of less than 30 days is referred to as a deployment. This term is commonly used in military contexts to describe the temporary assignment of personnel or equipment to a different location for a specific mission or operation. In this case, the MRSP kit is being temporarily relocated to another location for a short period of time before returning to its home station.

The proper tire pressure setting for highway towing of an R-14 air transportable hydrant refueling system (ATHRS) is 65 psi. This is the correct answer because maintaining the appropriate tire pressure is crucial for safe and efficient towing of heavy equipment like the ATHRS. Higher tire pressure helps to distribute the weight evenly and reduces the risk of tire damage or blowouts during towing. Therefore, ensuring that the tires are inflated to 65 psi is necessary to ensure the safe transportation of the ATHRS on the highway.

Priming the PMU-27M is necessary any time the system has been purged of fuel. When the system is purged of fuel, it means that there is no fuel in the system, which can result in air pockets. Priming the PMU-27M ensures that there are no air pockets in the fuel system, which can cause issues with fuel flow and engine performance. Therefore, it is necessary to prime the PMU-27M after the system has been purged of fuel to ensure proper functioning.

The PMU-27M may be connected to a maximum of four 500-gal. sealed drums.

The ABFDS contains 186 feet of connecting hose.

The R-22 trailer mounted transfer pump has the capability of transferring a maximum of 500,000 gallons of fuel per day.

The correct answer is "None". This means that there is no type of meter installed on the TPI-4T-4A portable additive injector. This suggests that the injector does not have a built-in mechanism for measuring or controlling the flow of additives.

When starting the PMU-27M, the throttle should be placed at half speed. This is because starting the engine at full speed can cause excessive wear and tear on the engine components. Starting at idle may not provide enough power to start the engine smoothly. Starting at two-thirds speed may be too high and may cause the engine to start abruptly. Therefore, half speed is the optimal choice for starting the PMU-27M.

Fuel bladders are made of single ply nylon fabric because it is a lightweight and durable material that is resistant to fuel and other chemicals. Nylon is also flexible, allowing the fuel bladder to be easily folded and stored when not in use. Additionally, the single ply construction ensures that the bladder is strong and leak-proof, providing a reliable containment system for fuel.

The correct answer is 7 ½ in. A 7 ½ in sealing clamp should be used to repair a 5 in. hole in a fuel bladder. The sealing clamp needs to be larger than the hole to ensure a secure and effective repair.

When performing fuel servicing operations with the R-20 multi-aircraft servicing platform, it is recommended to press and release the deadman switch on the hand-held remote at intervals no greater than 2 minutes. This is important to ensure the safety of the operation and to minimize any potential risks or accidents that may occur during the fuel servicing process. By regularly pressing and releasing the deadman switch, it helps to maintain control and monitoring of the fueling operation, allowing for prompt action if any issues arise.

It allows for the transfer of fuel and servicing of small aircraft that do not have access to permanent fuel systems.

The surge suppressor gauge on the R-20 multi-aircraft servicing unit should indicate 90 psi when the fueling system is not operating. This pressure is likely the optimal level for the surge suppressor to effectively regulate and stabilize any sudden changes or surges in the fueling system. It ensures that the system remains safe and prevents any potential damage or accidents.

JP-5 should be used to flush the R-14 prior to air shipment. This is because JP-5 is a type of jet fuel that is commonly used in military aircraft. It has a lower flash point and is less volatile compared to other jet fuels such as JP-4 and JP-8. Flushing the R-14 with JP-5 ensures that any residue or contaminants are removed effectively, preparing it for safe air shipment. JPTS is not a recognized grade of fuel and therefore not a suitable option for flushing the R-14.

During air shipment, it is important to ensure that the cryotainer inner tank pressure does not exceed a certain maximum psi reading. In this case, the correct answer is 40 psi. This means that the pressure inside the cryotainer should not go beyond 40 psi during air shipment. Exceeding this pressure limit could potentially lead to safety hazards or damage to the cryotainer or its contents.

Jet B should be handled with special precautions due to its high volatility. Volatility refers to the ability of a substance to vaporize quickly, and Jet B has a higher volatility compared to other alternate fuels listed. This means that it has a higher tendency to evaporate and form flammable vapors, which can increase the risk of fire or explosion. Therefore, special precautions need to be taken when handling and storing Jet B to ensure safety.

Fuel bladders are designed to hold and transport fuel safely. The given answer states that fuel bladders can withstand temperatures ranging from -40° F to 160° F. This means that the bladders are able to function and maintain their structural integrity within this temperature range. Temperatures below -40° F or above 160° F may cause damage to the bladders, potentially leading to leaks or other safety hazards. Therefore, it is important to operate fuel bladders within the specified temperature range to ensure their proper functioning and prevent any accidents or fuel loss.

The correct answer is 2 because the question asks for the number of fillstand assemblies included in the FORCE system. Since the answer options range from 1 to 4, we can determine that there are only 2 fillstand assemblies in the system.

A locally developed form is used to annotate fuel bladder inspections. This means that there is no standardized or official form specifically designated for this purpose. Instead, each organization or facility may create their own form to document and track fuel bladder inspections. This allows for flexibility and customization based on the specific needs and requirements of the organization.

The R-14 is capable of servicing a flow rate of 100 gpm through one 2-inch hose.

The R-19 filter separator unit is capable of filtering fuel at a maximum rate of 1200 gpm. This means that it can effectively remove impurities and contaminants from fuel at a flow rate of up to 1200 gallons per minute. It is important to have a high maximum gpm rate in order to ensure efficient and effective filtration of fuel in industrial or commercial settings where large volumes of fuel are being processed.

The correct answer is 2,250 rpm. When performing fuel servicing operations with the R-18 pumping unit, the throttle control should manually be set to 2,250 rpm. This specific rpm setting is likely recommended for optimal fuel efficiency and performance during fuel servicing operations.

The proper tire pressure setting for the R-18 pumping unit is 75 psi. This is the correct answer because it is the only option provided that matches the recommended tire pressure for the specific equipment mentioned.
