Backshop
A backshop or back-shop is a specialized store or workshop found in service industries, such as locomotive and aircraft repair. Most repairs are carried out in small workshops, except where an industrial service is needed. In the military, backshops repair parts are known as shop-replaceable units (SRUs). These are commonly-stocked subassemblies of a larger system, such as circuit cards components of a line-replaceable unit (LRU), designed to be repaired at the field level. Repair at this level is known as field-level maintenance or intermediate-level (I-level) maintenance. Calibration and repair of United States Air Force test equipment is conducted at shops known as precision measurement equipment laboratories.

Shop-replaceable Unit
A shop-replaceable unit (SRU) or shop-replaceable component (SRC) is a modular component of an airplane, ship or spacecraft that is designed to be replaced by a technician at a backshop. Repair at backshops is known as field-level maintenance or intermediate-level (I-level) maintenance. SRUs are similar in nature to line-replaceable units (LRUs), but rather than being complete functional units, represent component functions, such as circuit card assemblies, of a larger LRU. SRUs are typically assigned logistics control numbers (LCNs) or work unit codes (WUCs) to manage logistics operations. SRUs can be stocked to allow for quick remove and replace (R&R) operations on their parent LRUs or LLRUs, while also allowing for more extended repair operations at the backshop. Calibration and repair of United States Air Force test equipment is conducted at shops known as precision measurement equipment laboratories.

Level Of Repair Analysis
Level of Repair Analysis (LORA) is used as an analytical methodology used to determine where an item will be replaced, repaired, or discarded based on cost considerations and operational readiness requirements. For a complex engineering system containing thousands of assemblies, sub-assemblies, components, organized into several levels of indenture and with a number of possible repair decisions, LORA seeks to determine an optimal provision of repair and maintenance facilities to minimize overall system life-cycle costs. Logistics personnel examine not only the cost of the part to be replaced or repaired but all of the elements required to make sure the job is done correctly. This includes the skill level of personnel, support equipment required to perform the task, test equipment required to test the repaired product, and the facilities required to house the entire operation. Process LORA establishes when and where each unit will be repaired and determines if it is more cost eff ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Workshop
Beginning with the Industrial Revolution era, a workshop may be a room, rooms or building which provides both the area and tools (or machinery) that may be required for the manufacture or repair of manufactured goods. Workshops were the only places of production until the advent of industrialization and the development of larger factories. In the 20th and 21st century, many Western homes contained a workshop in either the garage, basement, or an external shed. Home workshops typically contain a workbench, hand tools, power tools, and other hardware. Along with the practical application of repairing goods, workshops are often used to tinker and make prototypes. Some workshops focus exclusively on automotive repair or restoration although there are a variety of workshops in existence today. Woodworking, metalworking, electronics, and other types of electronic prototyping workshops are among the most common. Backshop In some repair industries, such as locomotives and a ...

Precision Measurement Equipment Laboratory
A Precision Measurement Equipment Laboratory (PMEL) is a United States Air Force (USAF) facility in which the calibration and repair of test equipment takes place. This practice is also known as metrology: ''the science of measurement''. Metrology is defined as the science of weights & measures, while a PMEL is the place where technicians perform all of the metrology for the U.S. Air Force. Air personnel in this career field are primarily responsible for the repair, calibration, and modification of test, measurement, and diagnostic equipment (TMDE), including precision measurement equipment laboratory standards and automatic test equipment. They also supervise the process and use of TMDE to perform voltage, current, power, impedance, frequency, microwave, temperature, physical-dimensional, and optical measurements. They perform these functions in a strictly controlled laboratory environment where the temperature and humidity are constantly monitored. The Air Force Specialty Code (A ...

Military Maintenance
A military, also known collectively as armed forces, is a heavily armed, highly organized force primarily intended for warfare. It is typically authorized and maintained by a sovereign state, with its members identifiable by their distinct military uniform. It may consist of one or more military branches such as an army, navy, air force, space force, marines, or coast guard. The main task of the military is usually defined as defence of the state and its interests against external armed threats. In broad usage, the terms ''armed forces'' and ''military'' are often treated as synonymous, although in technical usage a distinction is sometimes made in which a country's armed forces may include both its military and other paramilitary forces. There are various forms of irregular military forces, not belonging to a recognized state; though they share many attributes with regular military forces, they are less often referred to as simply ''military''. A nation's military may ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Military Aviation
Military aviation comprises military aircraft and other flying machines for the purposes of conducting or enabling aerial warfare, including national airlift ( air cargo) capacity to provide logistical supply to forces stationed in a war theater or along a front. Airpower includes the national means of conducting such warfare, including the intersection of transport and warcraft. Military aircraft include bombers, fighters, transports, trainer aircraft, and reconnaissance aircraft. History The first military uses of aviation involved lighter-than-air balloons. During the Battle of Fleurus in 1794, the French observation balloon ''l'Entreprenant'' was used to monitor Austrian troop movements. The use of lighter-than-air aircraft in warfare became prevalent in the 19th century, including regular use in the American Civil War. Lighter-than-air military aviation persisted until shortly after World War II, gradually being withdrawn from various roles as heavier-than-air ...

Railway Workshop
Railway workshops are railway facilities in which rolling stock is repaired. While often colocated with engine sheds to perform routine tasks as well as major repairs, in some countries separated concepts exist with ''railway workshops'' being specialized in major repairs and general inspections. In German-speaking countries, the generic names ''Werkstatt'', or specifically in Austria ''Hauptwerkstatt'', are commonly used, except for Germany, where railway workshops maintained by Deutsche Bahn are called Ausbesserungswerk or simply ''Werk''.

Back Office
A back office in most corporations is where work that supports '' front office'' work is done. The front office is the "face" of the company and is all the resources of the company that are used to make sales and interact with customers and clients. The back office is all the resources of the company that are devoted to actually producing a product or service such as data entry, payroll, accounting and all the other labor that is not seen by customers, such as administration or logistics. Broadly speaking, back office work includes roles that affect the costs side of a business's trading statement and front office work includes roles that affect the income side of a business's trading statement. Although the operations of a back office are seldom prominent, they are a major contributor to a business's success. They can include functions such as accounting, planning, inventory management, supply-chain management, human resources and logistics Logistics is generally the ...

Armory (military)
An arsenal is a place where arms and ammunition are made, maintained and repaired, stored, or issued, in any combination, whether privately or publicly owned. Arsenal and armoury (British English) or armory (American English) are mostly regarded as synonyms, although subtle differences in usage exist. A sub-armory is a place of temporary storage or carrying of weapons and ammunition, such as any temporary post or patrol vehicle that is only operational in certain times of the day. Etymology The term in English entered the language in the 16th century as a loanword from french: arsenal, itself deriving from the it, arsenale, which in turn is thought to be a corruption of ar, دار الصناعة, , meaning "manufacturing shop". Types A lower-class arsenal, which can furnish the materiel and equipment of a small army, may contain a laboratory, gun and carriage factories, small-arms ammunition, small-arms, harness, saddlery tent and powder factories; in addition, it mu ...

United States Air Force
The United States Air Force (USAF) is the air service branch of the United States Armed Forces, and is one of the eight uniformed services of the United States. Originally created on 1 August 1907, as a part of the United States Army Signal Corps, the USAF was established as a separate branch of the United States Armed Forces in 1947 with the enactment of the National Security Act of 1947. It is the second youngest branch of the United States Armed Forces and the fourth in order of precedence. The United States Air Force articulates its core missions as air supremacy, global integrated intelligence, surveillance and reconnaissance, rapid global mobility, global strike, and command and control. The United States Air Force is a military service branch organized within the Department of the Air Force, one of the three military departments of the Department of Defense.

Electronic Test Equipment
Electronic test equipment is used to create signals and capture responses from electronic devices under test (DUTs). In this way, the proper operation of the DUT can be proven or faults in the device can be traced. Use of electronic test equipment is essential to any serious work on electronics systems. Practical electronics engineering and assembly requires the use of many different kinds of electronic test equipment ranging from the very simple and inexpensive (such as a test light consisting of just a light bulb and a test lead) to extremely complex and sophisticated such as automatic test equipment (ATE). ATE often includes many of these instruments in real and simulated forms. Generally, more advanced test gear is necessary when developing circuits and systems than is needed when doing production testing or when troubleshooting existing production units in the field. Types of test equipment Basic equipment The following items are used for basic measurement of voltages, c ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Locomotive
A locomotive or engine is a rail transport vehicle that provides the motive power for a train. If a locomotive is capable of carrying a payload, it is usually rather referred to as a multiple unit, motor coach, railcar or power car; the use of these self-propelled vehicles is increasingly common for passenger trains, but rare for freight (see CargoSprinter). Traditionally, locomotives pulled trains from the front. However, push-pull operation has become common, where the train may have a locomotive (or locomotives) at the front, at the rear, or at each end. Most recently railroads have begun adopting DPU or distributed power. The front may have one or two locomotives followed by a mid-train locomotive that is controlled remotely from the lead unit. __TOC__ Etymology The word ''locomotive'' originates from the Latin 'from a place', ablative of 'place', and the Medieval Latin 'causing motion', and is a shortened form of the term ''locomotive engine'', which was ...
