Aerospace Acronym and Abbreviation Guide
Aviation communication refers to the conversing of two or more aircraft. Aircraft are constructed in such a way that make it very difficult to see beyond what is directly in front of them. As safety is a primary focus in aviation, communication methods such as wireless radio are an effective way for aircraft to communicate with the necessary personnel. Aviation is an international industry and as a result involves multiple languages.
The industry considers that some pilots may not be fluent English speakers and as a result pilots are obligated to participate in an English proficiency test. Aviation communication is the means by which aircraft crews connect with other aircraft and people on the ground to relay information.
Aviation communication is a crucial component pertaining to the successful functionality of aircraft movement both on the ground and in the air. Increased communication reduces the risk of an accident. During the early stages of aviation, it was assumed that skies were too big and empty that it was impossible that two planes would collide. Aviation was roaring during the Jet Age and as a result, communication technologies needed to be developed.
This was initially seen as a very difficult task: ground controls used visual aids to provide signals to pilots in the air. With the advent of portable radios small enough to be placed in planes, pilots were able to communicate with people on the ground. With later developments, pilots were then able to converse air-to-ground and air-to-air.
Today, aviation communication relies heavily on the use of many systems. Planes are outfitted with the newest radio and GPS systems, as well as Internet and video capabilities. Flight was considered a foreign concept until the Wright Brothers successfully completed the world's first human flight in The industry grew rapidly and ground crews initially relied on coloured paddles, signal flares, hand signs, and other visual aids to communicate with incoming and outgoing aircraft.
Although these methods were effective for ground crews, they offered no way for pilots to communicate back. As wireless telegraphy technologies developed alongside the growth of aviation during the first decade of the twentieth century, wireless telegraph systems were used to send messages in Morse code , first from ground-to-air and later air-to-ground. With this technology, planes were able to call in accurate artillery fire and act as forward observers in warfare.
In , wireless telegraphy was put into operational use in the Italo-Turkish War. In , the Royal Flying Corps had begun experimenting with "wireless telegraphy" in aircraft. Lieutenant B. T James was a leading pioneer of wireless radio in aircraft.
In the spring of , James had begun to experiment with radios in a B. James managed to successfully increase the efficiency of wireless radio before he was shot down and killed by anti-aircraft fire on July 13, Nonetheless, wireless communication systems in aircraft remained experimental and would take years to successfully develop a practical prototype. The early radios were heavy in weight and were unreliable; additionally, ground forces rarely used radio because signals were easily intercepted and targeted by opposing forces.
At the beginning of World War I , aircraft were not typically equipped with wireless equipment. Instead, soldiers used large panel cut outs to distinguish friendly forces. These cut outs could also be used as a directional device to help pilots navigate back to friendly and familiar airfields.
In April , Captain J. Furnival was the first person to hear a voice from the ground from Major Prince who said, "If you can hear me now, it will be the first time speech has ever been communicated to an aeroplane in flight. Ground-to-air was initially by Morse code, but it is believed 2-way voice communications were available and installed by July Though few of these devices saw service in the war, they proved this was a viable and valuable technology worthy of refinement and advancement.
Following World War I new technology was developed to increase the range and performance of the radios being used to communicate with planes in the air. In December a year after the end of World War I , Hugh Trenchard, 1st Viscount Trenchard , a senior officer in the Royal Flying Corps RFC later Royal Air Force RAF , produced a report on the permanent organisation and operations of the RAF in peacetime in which he argued that if the air force officer was not to be a chauffeur, and nothing more, then navigation, meteorology, photography and wireless were necessities.
It was not until that airborne radios were reliable enough and had enough power to make them effective; and it was this year that the International Commission for Aerial Navigation agreed that all aircraft carrying 10 or more passengers should carry wireless equipment. The operating distance of radios increased much slower than the distance planes were able to travel. After an original two mile range for the two-way radio systems tested by had extended to ranges of an average of 20 miles, which remained a practical limit for medium sized aircraft.
As the speed of planes increased, this resulted in a plane reaching its destination before the message announcing its departure [ citation needed ]. This was a point-to-point communications system used by the US Army Air Corps, that allowed army air fields to remain in contact with planes throughout their entire flight.
It could also be used to disseminate weather reports and orders to military aircraft and act as an air traffic control for arrivals and departures at military airfields.
The development of radar in the mids proved a great advance in air-to-ground communication. Radar could be used to track planes in the air and determine distance, direction, speed and even type of aircraft. This allowed for better air traffic control as well as navigation aides for pilots. Radar also proved to be a valuable tool in targeting for bombers. Radar stations on the coast of Britain could aim two radar beams from separate locations on the coast towards Germany.
By aligning the two radar beams to intersect over the desired target, a town or factory for example, an aircraft could then follow one radar signal until it intersected with the other where it would then know to drop bombs. Single seat aircraft such as the Spitfire and Hurricane were equipped mostly with the TR set. Other systems employed were Eureka and the S-Phone , which enabled Special Operations Executive agents working behind enemy lines to communicate with friendly aircraft and coordinate landings and the dropping of agents and supplies.
Communication error can occur between pilots and between pilots and air traffic controllers. Communication error contains: . The more information needing transfer, the more chance for error. Sometimes lack of self-confidence and motivation affects expression in communication. Sources of communication error come from: phonology speech rate, stress, intonation, pauses , syntax language word patterns, sentence structure , semantics, and pragmatics language in context.
Even though English is the international aviation language, native English speakers still play a role in misunderstanding and situational awareness. The biggest problem regarding non-native English speakers' transmissions is speech rate.
In order to understand alternative and unfamiliar accents, people's rate of comprehension and response slows down. Accents also affect transmissions because of the different pronunciations across languages. According to US department of transportation's report, errors between pilots and controllers include: . The International Civil Aviation Organization established English as the international aviation language in to improve consistency, accuracy, and effectiveness of pilot - air traffic control communication.
Miscommunication between pilots and air traffic control is a prominent factor in fatal airplane crashes, airspace incidents, runway incursion, and mid-air collisions. Aviation English is the highly specialized language and sequences used by pilots, air traffic control, and other aviation personnel and it focuses on a particular pronunciation, vocabulary, grammatical structure, and discourse styles that are used in specific aviation-related contexts.
Standard phraseology is the specialized phrasing commonly used by the aviation community to effectively communicate, and plain language is a more normal language used in everyday life.
Many non-native English speaking pilots and air traffic controllers learn English during their flight training and use it in a highly practical level while safely operating an aircraft and maintaining the safety of airspace, which can be highly stressful. ICAO also established the Language Proficiency Requirements to try to rectify multiple issues regarding accents, terminology, and interpretation in communication.
Beginning in March , ICAO set out the requirement that all pilots flying international routes and air traffic control serving international airports and routes must be a Level 4 or above and will be continually reassessed every three years. English is the aviation language used by ICAO. Usually, human factors that affect communications include two aspects: direct, meaning the error caused by the language itself, which is the problem for non English speakers, and also indirect, with the gender, age, and experience impacting the communication in aviation.
As a result, both pilots and ATCs need to have enough English ability to accomplish their tasks. Through education to help improve aviation English, participants need not only focus on the textbook, but need experience in an actual environment such as lab experience to help speakers to improve their English fluency and avoid misunderstanding which helps non-English speakers to communicate normally.

Networking the sky with new aircraft communication technology
As the pilot of an aircraft, you must ensure that the aircraft is equipped with radio communications systems capable of continuous communication according to the class of flight you are conducting and the category of airspace in which you will be flying AIP GEN 1. This includes ensuring that the radio communication system is of an approved type. Class G — Certified, military aerodromes where the carriage and use of radio is required. Additionally, approved hand-held radios may be used by pilots of these aircraft when operating in Class G. Private aircraft without radio may be admitted to the CTRs for maintenance subject to the approval of the appropriate ATC unit.
Haynes ManualsThe Haynes Author : Dale Stacey Description:SynopsisTypically, there are over twenty radio systems on board the average commercial jet aircraft dealing with communication, navigation and surveillance functions. Very high frequency VHF air-to-ground communication is usually the main method of information and control exchange between pilot and air traffic control. Satellite and high frequency radio links are used to complement this system for long range or oceanic information exchanges. Other communications systems are required between the airline operation centre and the pilot and sometimes between the passengers and the ground. A comprehensive guide to current systems, networks and topologies, this book covers application requirements for communication and related radio-navigation and surveillance functions in aeronautical systems. There is also an insight into future possibilities as technologies progress and airspace operation and control scenarios change.

The Air Force is becoming a network-enabled paradigm, wherein many of its capabilities will be generated through, and dependent on, the integrated efforts of multiple components. This approach to operations is expected to result in greater agility and attendant tactical advantages. However, as is the case with any untested concept, there is a need for technology that enables the analysis and execution of the new paradigm.
Air transportation is expected to at least double by Coping with these needs and the resulting overcrowded sky requires top-notch communication technologies - but the sector is not quite ready yet. Whilst more and more airlines provide their customers with in-flight access to the internet, pilots still have to work with technology from another era.
Ты, часом, не шутишь? - Он был едва ли не на полметра выше этого панка и тяжелее килограммов на двадцать. - С чего это ты взял, что я шучу. Беккер промолчал. - Подними! - срывающимся голосом завопил панк. Беккер попробовал его обойти, но парень ему не позволил.
Хейл заломил руку Сьюзан за спину, и голова ее наклонилась. - Даю вам последний шанс, приятель. Где ваш пистолет.
Многоуровневая защита силовых и телефонных кабелей была спрятана глубоко под землей в стальных контейнерах, а питание от главного комплекса АНБ было дополнено многочисленными линиями электропитания, независимыми от городской системы снабжения. Поэтому отключение представляло собой сложную серию подтверждений и протоколов, гораздо более сложную, чем запуск ядерной ракеты с подводной лодки. - У нас есть время, но только если мы поспешим, - сказал Джабба. - Отключение вручную займет минут тридцать. Фонтейн по-прежнему смотрел на ВР, перебирая в уме остающиеся возможности.
- Что еще это может. Иначе Танкадо не отдал бы ключ. Какой идиот станет делать на кольце надпись из произвольных букв. Фонтейн свирепым взглядом заставил его замолчать. - Вы меня слышите? - вмешался Беккер, чувствуя себя неловко.
Ее обдало порывом воздуха, и машина проехала мимо. Но в следующее мгновение послышался оглушающий визг шин, резко затормозивших на цементном полу, и шум снова накатил на Сьюзан, теперь уже сзади. Секунду спустя машина остановилась рядом с .
Двухдюймовое искривленное стекло односторонней видимости открывало перед криптографами панораму зала, не позволяя увидеть камеру снаружи. В задней ее части располагались двенадцать терминалов, образуя совершенную окружность. Такая форма их размещения должна была способствовать интеллектуальному общению криптографов, напоминая им, что они всего лишь члены многочисленной команды - своего рода рыцари Круглого стола взломщиков кодов. По иронии судьбы в Третьем узле секреты не очень-то любили.
Голос его звучал спокойно и чуточку игриво. - Откроем пачку тофу. - Нет, спасибо.
