Proword
Procedure words (abbreviated to prowords) are words or phrases limited to radiotelephony procedure used to facilitate communication by conveying information in a condensed standard verbal format. Prowords are voice versions of the much older procedural signs for Morse code which were first developed in the 1860s for Morse telegraphy, and their meaning is identical. The NATO communications manual ACP-125 contains the most formal and perhaps earliest modern (post-World War II) glossary of prowords, but its definitions have been adopted by many other organizations, including the United Nations Development Programme, the U.S. Coast Guard, US Civil Air Patrol, US Military Auxiliary Radio System, and others. Prowords are one of several structured parts of radio voice procedures, including brevity codes and plain language radio checks. Examples According to the U.S. Marine Corps training document FMSO 108, "understanding the following PROWORDS and their respective definitions is ...

Radiotelephony Procedure
Radiotelephony procedure (also on-air protocol and voice procedure) includes various techniques used to clarify, simplify and standardize spoken communications over two-way radios, in use by the armed forces, in civil aviation, police and fire dispatching systems, citizens' band radio (CB), and amateur radio. Voice procedure communications are intended to maximize clarity of spoken communication and reduce errors in the verbal message by use of an accepted nomenclature. It consists of a signalling protocol such as the use of abbreviated codes like the CB radio ten-code, Q codes in amateur radio and aviation, police codes, etc., and jargon. Some elements of voice procedure are understood across many applications, but significant variations exist. The armed forces of the NATO countries have similar procedures in order to make cooperation easier. The impacts of having radio operators who are not well-trained in standard procedures can cause significant operational problems and dela ...

Plain Language Radio Checks
A plain-language radio check is the means of requesting and giving a signal strength and readability report for radiotelephony (voice) communications, and is the direct equivalent to the QSA and QRK code used to give the same report in radiotelegraph (Morse code) communications. SINPEMFO code is the voice signal reporting format developed by the ITU in 1959, but sees little use outside of shortwave listeners. Allied Communications Procedure 125(F), Communication Instructions Radiotelephone Procedure, published by the Combined Communication Electronics Board, defines radiotelephone procedures, and contains the original definitions for many common radio communications procedures, including Procedure Words, radio net operations, etc. Section 611 of ACP 125(F) details how to conduct radio checks using plain language. Radio check procedure The prowords listed below are for use when initiating and answering queries concerning signal strength and readability. Signal strength prowords ...

Prosigns For Morse Code
Procedural signs or prosigns are shorthand signals used in Morse code telegraphy, for the purpose of simplifying and standardizing procedural protocols for landline and radio communication. The procedural signs are distinct from conventional Morse code abbreviations, which consist mainly of brevity codes that convey messages to other parties with greater speed and accuracy. However, some codes are used ''both'' as prosigns and as single letters or punctuation marks, and for those, the distinction between a prosign and abbreviation is ambiguous, even in context. Overview In the broader sense prosigns are just standardised parts of short form radio protocol, and can include any abbreviation. Examples would be for "okay, heard you, continue" or for "message, received". In a more restricted sense, "prosign" refers to something analogous to the nonprinting control characters in teleprinter and computer character sets, such as Baudot and ASCII. Different from abbreviations, those a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Fire Discipline
Fire discipline is a system of communication in the military, primarily for directing artillery. By definition, fire discipline is the language of fire control. It consists of words, phrases, rules, and conventions which have specific meanings and which result in some definite action being taken with the guns. All ranks concerned in fire control must be thoroughly familiar with the language and the resulting actions. The aim of fire discipline is to ensure that in response to calls for fire (from a forward observer), the appropriate action is taken at the FPC (future planning cell), FSCC (fire support coordination center), FDC (fire direction center) and at the Guns/MRL, strictly in accordance with the intentions of the originator and with the minimum of delay. Six elements of a call for fire An initial call for fire (to an artillery battery) consists of six elements: *Observer identification *Warning order *Target location *Target description *Method of engagement *Method o ...

Signal Strength And Readability Report
A signal strength and readability report is a standardized format for reporting the strength of the radio signal and the readability (quality) of the radiotelephone (voice) or radiotelegraph (Morse code) signal transmitted by another station as received at the reporting station's location and by their radio station equipment. These report formats are usually designed for only one communications mode or the other, although a few are used for both telegraph and voice communications. All but one of these signal report formats involve the transmission of numbers. History As the earliest radio communication used Morse code, all radio signal reporting formats until about the 1920s were for radiotelegraph, and the early voice radio signal report formats were based on the telegraph report formats. Timeline of signal report formats * The first signal report format code may have been QJS. * The U.S. Navy used R and K signals starting in 1929. * The QSK code was one of the twelve Q Co ...

International Convention On Standards Of Training, Certification And Watchkeeping For Seafarers
International Convention on Standards of Training, Certification and Watchkeeping for Seafarers (STCW) sets minimum qualification standards for masters, officers and watch personnel on seagoing merchant ships and large yachts. STCW was adopted in 1978 by the International Maritime Organization (IMO) conference in London, and entered into force in 1984. The convention was significantly amended in 1995 and 2010, and entered into force on 1 January 2012. The 1978 STCW Convention Caruso was the first to establish minimum basic requirements on training, certification and watchkeeping for seafarers on an international level. Previously the minimum standards of training, certification and watchkeeping of officers and ratings were established by individual governments, usually without reference to practices in other countries. As a result, minimum standards and procedures varied widely, even though shipping is extremely international by nature. The convention prescribes minimum sta ...

Gross Tonnage
Gross tonnage (GT, G.T. or gt) is a nonlinear measure of a ship's overall internal volume. Gross tonnage is different from gross register tonnage. Neither gross tonnage nor gross register tonnage should be confused with measures of mass or weight such as deadweight tonnage or displacement. Gross tonnage, along with net tonnage, was defined by the ''International Convention on Tonnage Measurement of Ships, 1969'', adopted by the International Maritime Organization (IMO) in 1969, and came into force on 18 July 1982. These two measurements replaced gross register tonnage (GRT) and net register tonnage (NRT). Gross tonnage is calculated based on "the moulded volume of all enclosed spaces of the ship" and is used to determine things such as a ship's manning regulations, safety rules, registration fees, and port dues, whereas the older gross register tonnage is a measure of the volume of only certain enclosed spaces. History The International Convention on Tonnage Measurement of ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Air Traffic Control
Air traffic control (ATC) is a service provided by ground-based air traffic controllers who direct aircraft on the ground and through a given section of controlled airspace, and can provide advisory services to aircraft in non-controlled airspace. The primary purpose of ATC is to prevent collisions, organise and expedite the flow of traffic in the air, and provide information and other support for pilots. Personnel of air traffic control monitor aircraft location in their assigned airspace by radar and communicate with the pilots by radio. To prevent collisions, ATC enforces Separation (air traffic control), traffic separation rules, which ensure each aircraft maintains a minimum amount of 'empty space' around it at all times. It is also common for ATC to provide services to all General aviation, private, Military aviation, military, and commercial aircraft operating within its airspace; not just civilian aircraft. Depending on the type of flight and the class of airspace, AT ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Convention On International Civil Aviation
The Convention on International Civil Aviation, also known as the Chicago Convention, established the International Civil Aviation Organization (ICAO), a specialized agency of the United Nations charged with coordinating international air travel. The convention establishes rules of airspace, aircraft registration and safety, security, and sustainability, and details the rights of the signatories in relation to air travel. The convention also contains provisions pertaining to taxation. The document was signed on December 7, 1944, in Chicago by 52 signatory states. It received the requisite 26th ratification on March 5, 1947, and went into effect on April 4, 1947, the same date that ICAO came into being. In October of the same year, ICAO became a specialized agency of the United Nations Economic and Social Council (ECOSOC). The convention has since been revised eight times (in 1959, 1963, 1969, 1975, 1980, 1997, 2000 and 2006). the Chicago Convention had 193 state parties, wh ...

Calshot Spit
Calshot Spit is a one-mile long sand and shingle bank, near the village of Calshot, located on the southern bank of the open end of Southampton Water, on the south coast of England.OS Explorer Map, New Forest, Scale: 1:25 000.Publisher: Ordnance Survey B4 edition (2013). At the end of the spit are Calshot Castle (built by King Henry VIII), an RNLI lifeboat, an NCI station, several slipways, a former Royal Navy and Royal Air Force flying boat station and Calshot Activities Centre. The neck of the spit is owned by New Forest District Council while the end of the spit is owned by the Crown Estate which leases it to Hampshire County Council. History The castle is a low, circular, stone structure and was armed with large muzzle-loading guns. Its purpose, when it was built in 1539, was to protect access to the important harbour at Southampton from seaborne attack, by France or Spain from the English Channel via the Solent. For much of its history the spit was low lying and ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Mnemonic
A mnemonic device ( ), memory trick or memory device is any learning technique that aids information retention or retrieval in the human memory, often by associating the information with something that is easier to remember. It makes use of elaborative encoding, retrieval cues and imagery as specific tools to encode information in a way that allows for efficient storage and retrieval. It aids original information in becoming associated with something more accessible or meaningful—which in turn provides better retention of the information. Commonly encountered mnemonics are often used for lists and in auditory system, auditory form such as Acrostic, short poems, acronyms, initialisms or memorable phrases. They can also be used for other types of information and in visual or kinesthetic forms. Their use is based on the observation that the human mind more easily remembers spatial, personal, surprising, physical, sexual, humorous and otherwise "relatable" information rather tha ...

Royal Yachting Association
The Royal Yachting Association (RYA) is a United Kingdom national governing body for sailing, dinghy sailing, yacht and motor cruising, sail racing, RIBs and sportsboats, windsurfing and personal watercraft and a leading representative for inland waterways cruising. History The ''Yacht Racing Association'' was founded in November 1875. Its initial purpose was to standardize the rules of measurement to different racing yachts so that boats of different classes could compete fairly against each other. Membership at the time cost two guineas and was available to "former and present owners of racing yachts of and above 10 tons Thames measurement and such other gentlemen as the committee may elect". In 1921 the YRA incorporated the independent Sailing Boat Association and the Boat Racing Association into its body. In 1952 the YRA became the Royal Yachting Association (RYA). The RYA remains constituted as a membership association, with a Council of elected volunteers as its sup ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
