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. See also * Armory (military) * Back office * 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 co ...

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 aircraf ...

Aircraft Maintenance
Aircraft maintenance is the performance of tasks required to ensure the continuing airworthiness of an aircraft or aircraft part, including overhaul, inspection, replacement, defect rectification, and the embodiment of modifications, compliance with airworthiness directives and repair. Regulation The maintenance of aircraft is highly regulated, in order to ensure safe and correct functioning during flight. In civil aviation national regulations are coordinated under international standards, established by the International Civil Aviation Organization (ICAO). The ICAO standards have to be implemented by local airworthiness authorities to regulate the maintenance tasks, personnel and inspection system. Maintenance staff must be licensed for the tasks they carry out. Major airworthiness regulatory authorities include the US Federal Aviation Administration (FAA), European Union Aviation Safety Agency (EASA), Australian Transport Safety Bureau(ATSB), Transport Canada (TC) and Indian ...

Repairs
The technical meaning of maintenance involves functional checks, servicing, repairing or replacing of necessary devices, equipment, machinery, building infrastructure, and supporting utilities in industrial, business, and residential installations. Over time, this has come to include multiple wordings that describe various cost-effective practices to keep equipment operational; these activities occur either before or after a failure. Definitions Maintenance functions can defined as maintenance, repair and overhaul (MRO), and MRO is also used for maintenance, repair and operations. Over time, the terminology of maintenance and MRO has begun to become standardized. The United States Department of Defense uses the following definitions:Federal Standard 1037C and from MIL-STD-188 and from the Department of Defense Dictionary of Military and Associated Terms * Any activity—such as tests, measurements, replacements, adjustments, and repairs—intended to retain or restore a func ...

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.

Line-replaceable Unit
A line-replaceable unit (LRU), lower line-replaceable unit (LLRU), line-replaceable component (LRC), or line-replaceable item (LRI) is a modular component of an airplane, ship or spacecraft (or any other manufactured device) that is designed to be replaced quickly at an operating location (1st line). The different lines (distances) are essential for logistics planning and operation. An LRU is usually a sealed unit such as a radio or other auxiliary equipment. LRUs are typically assigned logistics control numbers (LCNs) or work unit codes (WUCs) to manage logistics operations. LRUs can improve maintenance operations, because they can be stocked and replaced quickly from distributed nearby on-site inventories (sometimes mobile storage), restoring the mobile systems to service, while the failed (unserviceable) LRU is undergoing complicated repair and overhaul actions in other support locations (lines). Because of their modularity, LRUs also can contribute reducing system costs and i ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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 ef ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Calibration
In measurement technology and metrology, calibration is the comparison of measurement values delivered by a device under test with those of a calibration standard of known accuracy. Such a standard could be another measurement device of known accuracy, a device generating the quantity to be measured such as a voltage, a sound tone, or a physical artifact, such as a meter ruler. The outcome of the comparison can result in one of the following: * no significant error being noted on the device under test * a significant error being noted but no adjustment made * an adjustment made to correct the error to an acceptable level Strictly speaking, the term "calibration" means just the act of comparison and does not include any subsequent adjustment. The calibration standard is normally traceable to a national or international standard held by a metrology body. BIPM Definition The formal definition of calibration by the International Bureau of Weights and Measures (BIPM) is the fo ...

Locomotive
A locomotive or engine is a rail transport vehicle that provides the Power (physics), 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 (rail), 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 train, 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 language, Latin 'from a place', Ablative case, ablative of 'place', and the Medieval Latin 'causing mot ...

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, cu ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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 ...

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 m ...
