96-463: Other names which have been applied to Central European Summer Time are Middle European Summer Time (MEST), Central European Daylight Saving Time (CEDT), and Bravo Time (after the second letter of the NATO phonetic alphabet ). Since 1996, European Summer Time has been observed between 01:00 UTC (02:00 CET and 03:00 CEST) on the last Sunday of March, and 01:00 UTC on the last Sunday of October; previously

192-466: A "prior experience" bid, where anyone with an FAA Control Tower Operator certificate (CTO) and 52 weeks of experience could apply. This was a revolving bid, every month the applicants on this bid were sorted out, and eligible applicants were hired and sent directly to facilities, bypassing the FAA academy entirely. In the process of promoting diversity, the FAA revised its hiring process. The FAA later issued

288-512: A ] [ aː ] [ ɑ ] [ ɑː ] [ ə ] . The DIN consolidated all six into the single low-central vowel [a] . The DIN vowels are partly predictable, with [ ɪ ɛ ɔ ] in closed syllables and [ i e / ei̯ o ] in open syllables apart from echo and sierra , which have [ɛ] as in English, German and Italian. The DIN also reduced the number of stressed syllables in bravo and x-ray , consistent with

384-536: A CTI certificate allowed a prospective controller to skip the Air Traffic Basics part of the academy, about a 30- to 45-day course, and go right into Initial Qualification Training (IQT). All prospective controllers, CTI or not, have had to pass the FAA Academy in order to be hired as a controller. Failure at the academy means FAA employment is terminated. In January 2015 they launched another pipeline,

480-636: A Special Agent with the Office of Inspector General for the Department of Transportation and with FAA Security, is one of the most outspoken critics of FAA. Rather than commend the agency for proposing a $ 10.2 million fine against Southwest Airlines for its failure to conduct mandatory inspections in 2008, he was quoted as saying the following in an Associated Press story: "Penalties against airlines that violate FAA directives should be stiffer. At $ 25,000 per violation, Gutheinz said, airlines can justify rolling

576-519: A college that offered a CTI program. Before the change, candidates who had completed coursework at participating colleges and universities could be "fast-tracked" for consideration. However, the CTI program had no guarantee of a job offer, nor was the goal of the program to teach people to work actual traffic. The goal of the program was to prepare people for the FAA Academy in Oklahoma City, OK. Having

672-732: A credit agreement or confirm stock codes), although ad-hoc code words are often used in that instance. It has been used by information technology workers to communicate serial numbers and reference codes, which are often very long, by voice. Most major airlines use the alphabet to communicate passenger name records (PNRs) internally, and in some cases, with customers. It is often used in a medical context as well. Several codes words and sequences of code words have become well-known, such as Bravo Zulu (letter code BZ) for "well done", Checkpoint Charlie (Checkpoint C) in Berlin, and Zulu Time for Greenwich Mean Time or Coordinated Universal Time . During

A Designated Engineering Representative (DER) is an engineer who is appointed under 14 CFR section 183.29 to act on behalf of a company or as an independent consultant (IC). The DER system enables the FAA to delegate certain involvement in airworthiness exams, tests, and inspections to qualified technical people outside of

864-483: A flight instructor (Gold Seal certification), a 50-year aviator (Wright Brothers Master Pilot Award), a 50-year mechanic (Charles Taylor Master Mechanic Award) or as a proficient pilot. The latter, the FAA " WINGS Program ", provides a lifetime series of grouped proficiency activities at three levels (Basic, Advanced, and Master) for pilots who have undergone several hours of ground and flight training since their last WINGS award, or "Phase". The FAA encourages volunteerism in

960-429: A four-year degree or five years of full-time work experience to apply, rather than the closed college program or Veterans Recruitment Appointment bids, something that had last been done in 2008. Thousands were hired, including veterans, Collegiate Training Initiative graduates, and people who are true "off the street" hires. The move was made to open the job up to more people who might make good controllers but did not go to

1056-408: A low level of intelligibility, but that most of the deficiencies could be remedied by the judicious selection of words from the commercial codes and those tested by the laboratory. In a few instances where none of the 250 words could be regarded as especially satisfactory, it was believed possible to discover suitable replacements. Other words were tested and the most intelligible ones were compared with

1152-425: A new airport aid program and certain added responsibilities for airport safety. During the 1960s and 1970s, the FAA also started to regulate high altitude (over 500 feet) kite and balloon flying. By the mid-1970s, the agency had achieved a semi-automated air traffic control system using both radar and computer technology. This system required enhancement to keep pace with air traffic growth, however, especially after

1248-706: A new independent agency, the Civil Aeronautics Authority . The legislation also expanded the government's role by giving the CAA the authority and the power to regulate airline fares and to determine the routes that air carriers would serve. President Franklin D. Roosevelt split the authority into two agencies in 1940: the Civil Aeronautics Administration (CAA) and the Civil Aeronautics Board (CAB). CAA

1344-427: A new spelling alphabet. The directions of ICAO were that "To be considered, a word must: After further study and modification by each approving body, the revised alphabet was adopted on 1 November 1951 , to become effective on 1 April 1952 for civil aviation (but it may not have been adopted by any military). Problems were soon found with this list. Some users believed that they were so severe that they reverted to

1440-425: A report that the "bio-data" was not a reliable test for future performance. However, the "Bio-Q" was not the determining factor for hiring, it was merely a screening tool to determine who would take a revised Air Traffic Standardized Aptitude Test (ATSAT). Due to cost and time, it was not practical to give all 30,000 some applicants the revised ATSAT, which has since been validated. In 2015 Fox News levied criticism that

1536-670: A series of midair collisions—most notably the 1956 Grand Canyon mid-air collision ) prompted passage of the Federal Aviation Act of 1958 . This legislation passed the CAA's functions to a new independent body, the Federal Aviation Agency. The act also transferred air safety regulation from the CAB to the FAA, and gave it sole responsibility for a joint civil-military system of air navigation and air traffic control. The FAA's first administrator, Elwood R. Quesada ,

1632-577: A spelling alphabet. The US adopted the Joint Army/Navy radiotelephony alphabet during 1941 to standardize systems among all branches of its armed forces. The US alphabet became known as Able Baker after the words for A and B. The Royal Air Force adopted one similar to the United States one during World War II as well. Other British forces adopted the RAF radio alphabet , which is similar to

1728-487: Is a rarely used variant that differs in the code words for digits. Although spelling alphabets are commonly called "phonetic alphabets", they are not phonetic in the sense of phonetic transcription systems such as the International Phonetic Alphabet . To create the code, a series of international agencies assigned 26 clear-code words (also known as "phonetic words") acrophonically to

1824-630: Is a set of programs to implement a suite of incremental changes to the National Airspace System (NAS). More precise Performance Based Navigation can reduce fuel burn, emissions, and noise exposure for a majority of communities, but the concentration of flight tracks also can increase noise exposure for people who live directly under those flight paths. A feature of the NextGen program is GPS-based waypoints, which result in consolidated flight paths for planes. The result of this change

1920-649: Is an accepted version of this page The International Radiotelephony Spelling Alphabet or simply the Radiotelephony Spelling Alphabet , commonly known as the NATO phonetic alphabet , is the most widely used set of clear-code words for communicating the letters of the Roman alphabet. Technically a radiotelephonic spelling alphabet , it goes by various names, including NATO spelling alphabet , ICAO phonetic alphabet , and ICAO spelling alphabet . The ITU phonetic alphabet and figure code

2016-637: Is appointed for a five-year term. On March 19, 2019, President Donald Trump announced he would nominate Stephen Dickson, a former executive and pilot at Delta Air Lines , to be the next FAA Administrator. On July 24, 2019, the Senate confirmed Dickson by a vote of 52–40. He was sworn in as Administrator by Transportation Secretary Elaine Chao on August 12, 2019. On February 16, 2022, Dickson announced his resignation as FAA Administrator, effective March 31, 2022. In September 2023, President Joe Biden announced that he would be nominating Mike Whitaker to lead

2112-418: Is in most European languages because the spelling Alpha may not be pronounced properly by native speakers of some languages – who may not know that ph should be pronounced as f . The spelling Juliett is used rather than Juliet for the benefit of French speakers, because they may otherwise treat a single final t as silent. For similar reasons, Charlie and Uniform have alternative pronunciations where

2208-637: Is occasional regional substitution of a few code words, such as replacing them with earlier variants, to avoid confusion with local terminology. Federal Aviation Administration The Federal Aviation Administration ( FAA ) is a U.S. federal government agency within the U.S. Department of Transportation which regulates civil aviation in the United States and surrounding international waters . Its powers include air traffic control , certification of personnel and aircraft , setting standards for airports, and protection of U.S. assets during

2304-449: Is preceded and followed by the words "as a number" spoken twice. The ITU adopted the IMO phonetic spelling alphabet in 1959, and in 1969 specified that it be "for application in the maritime mobile service only". Pronunciation was not defined prior to 1959. For the post-1959 phonetics, the underlined syllable of each letter word should be emphasized, and each syllable of the code words for

2400-462: Is present, as is commonly the case with radio and telephonic communication. For instance, the target message "proceed to map grid DH98" would be transmitted as proceed to map grid Delta-Hotel-Niner-Ait . Civilian industry uses the code words to avoid similar problems in the transmission of messages by telephone systems. For example, it is often used in the retail industry where customer or site details are conveyed by telephone (for example to authorize

2496-582: Is rendered as one seven and 60 as six zero . Depending on context, the word thousand may be used as in English, and for whole hundreds only (when the sequence 00 occurs at the end of a number), the word hundred may be used. For example, 1300 is read as one three zero zero if it is a transponder code or serial number, and as one thousand three hundred if it is an altitude or distance. The ICAO, NATO, and FAA use modifications of English digits as code words, with 3, 4, 5 and 9 being pronounced tree , fower (rhymes with lower ), fife and niner . The digit 3

2592-509: Is specified as tree so that it will not be mispronounced sri (and similarly for thousand ); the long pronunciation of 4 (still found in some English dialects) keeps it somewhat distinct from for ; 5 is pronounced with a second "f" because the normal pronunciation with a "v" is easily confused with "fire"; and 9 has an extra syllable to keep it distinct from the German word nein "no". (Prior to 1956, three and five had been pronounced with

2688-615: Is that many localities experience huge increases in air traffic over previously quiet areas. Complaints have risen with the added traffic and multiple municipalities have filed suit. As a result of the March 10, 2019 Ethiopian Airlines Flight 302 crash and the Lion Air Flight 610 crash five months earlier, most airlines and countries began grounding the Boeing 737 MAX 8 (and in many cases all MAX variants) due to safety concerns, but

2784-648: Is the cornerstone of the U.S. federal government 's regulation of civil aviation. This landmark legislation was passed at the urging of the aviation industry, whose leaders believed the airplane could not reach its full commercial potential without federal action to improve and maintain safety standards. The Act charged the Secretary of Commerce with fostering air commerce, issuing and enforcing air traffic rules, licensing pilots , certifying aircraft, establishing airways, and operating and maintaining aids to air navigation. The newly created Aeronautics Branch, operating under

2880-482: The Airline Deregulation Act of 1978 phased out the CAB's economic regulation of the airlines. A nationwide strike by the air traffic controllers union in 1981 forced temporary flight restrictions but failed to shut down the airspace system. During the following year, the agency unveiled a new plan for further automating its air traffic control facilities, but progress proved disappointing. In 1994,

2976-621: The Department of Commerce assumed primary responsibility for aviation oversight. In fulfilling its civil aviation responsibilities, the U.S. Department of Commerce initially concentrated on such functions as safety regulations and the certification of pilots and aircraft. It took over the building and operation of the nation's system of lighted airways, a task initiated by the Post Office Department . The Department of Commerce improved aeronautical radio communications—before

The 26 code words are as follows (ICAO spellings): Alfa , Bravo , Charlie , Delta , Echo , Foxtrot , Golf , Hotel , India , Juliett , Kilo , Lima , Mike , November , Oscar , Papa , Quebec , Romeo , Sierra , Tango , Uniform , Victor , Whiskey , X-ray , Yankee , and Zulu . ⟨Alfa⟩ and ⟨Juliett⟩ are spelled that way to avoid mispronunciation by people unfamiliar with English orthography ; NATO changed ⟨X-ray⟩ to ⟨Xray⟩ for

3264-588: The Vietnam War , the US government referred to the Viet Cong guerrillas and the group itself as VC, or Victor Charlie; the name "Charlie" became synonymous with this force. The final choice of code words for the letters of the alphabet and for the digits was made after hundreds of thousands of comprehension tests involving 31 nationalities. The qualifying feature was the likelihood of a code word being understood in

3360-482: The ch is pronounced "sh" and the u is pronounced "oo". Early on, the NATO alliance changed X-ray to Xray in its version of the alphabet to ensure that it would be pronounced as one word rather than as two, while the global organization ICAO keeps the spelling X-ray . The alphabet is defined by various international conventions on radio, including: For the 1938 and 1947 phonetics, each transmission of figures

3456-648: The fuselage of an aircraft , but was prevented by supervisors he said were friendly with the airline. This was validated by a report by the Department of Transportation which found FAA managers had allowed Southwest Airlines to fly 46 airplanes in 2006 and 2007 that were overdue for safety inspections, ignoring concerns raised by inspectors. Audits of other airlines resulted in two airlines grounding hundreds of planes, causing thousands of flight cancellations. The House Transportation and Infrastructure Committee held hearings in April 2008. Jim Oberstar , former chairman of

3552-411: The 1960s had already brought the agency into the field of civil aviation security. In response to the hijackings on September 11, 2001, this responsibility is now primarily taken by the Department of Homeland Security . The FAA became more involved with the environmental aspects of aviation in 1968 when it received the power to set aircraft noise standards. Legislation in 1970 gave the agency management of

3648-616: The 24-series. Several of these documents had revisions, and were renamed. For instance, CCBP3-2 was the second edition of CCBP3. During World War II, the US military conducted significant research into spelling alphabets. Major F. D. Handy, directorate of Communications in the Army Air Force (and a member of the working committee of the Combined Communications Board), enlisted the help of Harvard University's Psycho-Acoustic Laboratory, asking them to determine

For directions presented as the hour-hand position on a clock, the additional numerals "ten", "eleven" and "twelve" are used with the word "o'clock". The ITU and IMO, however, specify a different set of code words. These are compounds of ICAO and Latinesque roots. The IMO's GMDSS procedures permits the use of either set of code words. There are two IPA transcriptions of

3840-419: The FAA and Boeing had colluded on recertification test flights, attempted to cover up important information and that the FAA had retaliated against whistleblowers. SpaceX CEO Elon Musk criticized the FAA as moving too slowly, after a 2020 launch of a Starship prototype rocket violated the company's license. Musk said the agency's regulations are tailored for "a handful of expendable launches per year from

3936-474: The FAA announced it will allow airlines to expand the passengers use of portable electronic devices during all phases of flight, but mobile phone calls would still be prohibited (and use of cellular networks during any point when aircraft doors are closed remains prohibited to-date). Implementation initially varied among airlines. The FAA expected many carriers to show that their planes allow passengers to safely use their devices in airplane mode , gate-to-gate, by

4032-771: The FAA called the Air Traffic Organization , (ATO) was set up by presidential executive order. This became the air navigation service provider for the airspace of the United States and for the New York (Atlantic) and Oakland (Pacific) oceanic areas. It is a full member of the Civil Air Navigation Services Organisation . The FAA issues a number of awards to holders of its certificates. Among these are demonstrated proficiencies as an aviation mechanic (the AMT Awards),

4128-483: The FAA declined to ground MAX 8 aircraft operating in the U.S. On March 12, the FAA said that its ongoing review showed "no systemic performance issues and provides no basis to order grounding the aircraft." Some U.S. Senators called for the FAA to ground the aircraft until an investigation into the cause of the Ethiopian Airlines crash was complete. U.S. Transportation Secretary Elaine Chao said that "If

4224-441: The FAA discriminated against qualified candidates. In December 2015, a reverse discrimination lawsuit was filed against the FAA seeking class-action status for the thousands of men and women who spent up to $ 40,000 getting trained under FAA rules before they were abruptly changed. The prospects of the lawsuit are unknown, as the FAA is a self-governing entity and therefore can alter and experiment with its hiring practices, and there

4320-514: The FAA identifies an issue that affects safety, the department will take immediate and appropriate action." The FAA resisted grounding the aircraft until March 13, 2019, when it received evidence of similarities in the two accidents. By then, 51 other regulators had already grounded the plane, and by March 18, 2019, all 387 aircraft in service were grounded. Three major U.S. airlines-- Southwest , United , and American Airlines —were affected by this decision. Further investigations also revealed that

4416-432: The FAA proposed to fine Southwest $ 10.2 million for failing to inspect older planes for cracks, and in 2009 Southwest and the FAA agreed that Southwest would pay a $ 7.5 million penalty and would adopt new safety procedures, with the fine doubling if Southwest failed to follow through. In 2014, the FAA modified its approach to air traffic control hiring. It launched more "off the street bids", allowing anyone with either

4512-431: The FAA shifted to a more step-by-step approach that has provided controllers with advanced equipment. In 1979, Congress authorized the FAA to work with major commercial airports to define noise pollution contours and investigate the feasibility of noise mitigation by residential retrofit programs. Throughout the 1980s, these charters were implemented. In the 1990s, satellite technology received increased emphasis in

4608-450: The FAA when acting under the authority of a DER appointment; a DER has no federal protection for work done or the decisions made as a DER. Neither does the FAA provide any indemnification for a DER from general tort law . "The FAA cannot shelter or protect DERs from the consequences of their findings." A DAR is an individual appointed in accordance with 14 CFR 183.33 who may perform examination, inspection, and testing services necessary to

4704-532: The FAA's development programs as a means to improvements in communications, navigation, and airspace management. In 1995, the agency assumed responsibility for safety oversight of commercial space transportation, a function begun eleven years before by an office within DOT headquarters. The agency was responsible for the decision to ground flights after the September 11 attacks . In December 2000, an organization within

Working procedures for DERs are prescribed in FAA Order 8110.37 , Designated Engineering Representative (DER) Handbook . Neither type of DER is an employee of either the FAA or the United States government. While a DER represents

4896-446: The FAA. Whitaker previously served as deputy administrator of the FAA under President Barack Obama . The FAA has been cited as an example of regulatory capture , "in which the airline industry openly dictates to its regulators its governing rules, arranging for not only beneficial regulation, but placing key people to head these regulators." Retired NASA Office of Inspector General Senior Special Agent Joseph Gutheinz , who used to be

4992-733: The Federal Aviation Administration as it became one of several agencies (e.g., Federal Highway Administration, Federal Railroad Administration, the Coast Guard, and the Saint Lawrence Seaway Commission) within DOT. The FAA administrator no longer reported directly to the president, but instead to the Secretary of Transportation. New programs and budget requests would have to be approved by DOT, which would then include these requests in

5088-481: The ICAO English respellings of those words and with the NATO change of spelling of x-ray to xray so that people would know to pronounce it as a single word. There is no authoritative IPA transcription of the digits. However, there are respellings into both English and French, which can be compared to clarify some of the ambiguities and inconsistencies. CCEB has code words for punctuation, including those in

5280-475: The International Community (commonly abbreviated as CANIC) is a notification from the FAA to civil airworthiness authorities of foreign countries of pending significant safety actions. The FAA Airworthiness Directives Manual, states the following: 8. Continued Airworthiness Notification to the International Community (CANIC). The FAA issued a CANIC to state the continued airworthiness of

5376-724: The US military's Joint Army/Navy alphabet for use by all three nations, with the result being called the US-UK spelling alphabet. It was defined in one or more of CCBP-1: Combined Amphibious Communications Instructions , CCBP3: Combined Radiotelephone (R/T) Procedure , and CCBP-7: Combined Communication Instructions. The CCB alphabet itself was based on the US Joint Army/Navy spelling alphabet. The CCBP (Combined Communications Board Publications) documents contain material formerly published in US Army Field Manuals in

5472-579: The aftermath of the Southwest Airlines inspection scandal, a bill was unanimously approved in the House to tighten regulations concerning airplane maintenance procedures, including the establishment of a whistleblower office and a two-year "cooling off" period that FAA inspectors or supervisors of inspectors must wait before they can work for those they regulated. The bill also required rotation of principal maintenance inspectors and stipulated that

5568-645: The airways. In 1936, the Bureau itself took over the centers and began to expand the ATC system. The pioneer air traffic controllers used maps, blackboards, and mental calculations to ensure the safe separation of aircraft traveling along designated routes between cities. In 1938, the Civil Aeronautics Act transferred the federal civil aviation responsibilities from the Commerce Department to

5664-426: The committee, said its investigation uncovered a pattern of regulatory abuse and widespread regulatory lapses, allowing 117 aircraft to be operated commercially although not in compliance with FAA safety rules . Oberstar said there was a "culture of coziness" between senior FAA officials and the airlines and "a systematic breakdown" in the FAA's culture that resulted in "malfeasance, bordering on corruption". In 2008

5760-513: The context of others. For example, Football has a higher chance of being understood than Foxtrot in isolation, but Foxtrot is superior in extended communication. Pronunciations were set out by the ICAO before 1956 with advice from the governments of both the United States and United Kingdom. To eliminate national variations in pronunciation, posters illustrating the pronunciation desired by ICAO are available. However, there remain differences in

5856-564: The dice and taking the chance on getting caught. He also said the FAA is often too quick to bend to pressure from airlines and pilots." Other experts have been critical of the constraints and expectations under which the FAA is expected to operate. The dual role of encouraging aerospace travel and regulating aerospace travel are contradictory. For example, to levy a heavy penalty upon an airline for violating an FAA regulation which would impact their ability to continue operating would not be considered encouraging aerospace travel.

The ban was extended for a further 24 hours but was lifted about six hours later. The FAA Reauthorization Act of 2018 gives the FAA one year to establish minimum pitch, width and length for airplane seats, to ensure they are safe for passengers. The first FAA licensed orbital human space flight took place on November 15, 2020 , carried out by SpaceX on behalf of NASA. The administrator

Mobile phones must be in airplane mode or with mobile service disabled, with no signal bars displayed, and cannot be used for voice communications due to Federal Communications Commission regulations that prohibit any airborne calls using mobile phones. From a technological standpoint, cellular service would not work in-flight because of

6144-447: The firmest conclusions reached was that it was not practical to make an isolated change to clear confusion between one pair of letters. To change one word involves reconsideration of the whole alphabet to ensure that the change proposed to clear one confusion does not itself introduce others. Soon after the code words were developed by ICAO (see history below), they were adopted by other national and international organizations, including

6240-543: The founding of the Federal Communications Commission in 1934, which handles most such matters today—and introduced radio beacons as an effective aid to air navigation. The Aeronautics Branch was renamed the Bureau of Air Commerce in 1934 to reflect its enhanced status within the Department. As commercial flying increased, the Bureau encouraged a group of airlines to establish the first three centers for providing air traffic control (ATC) along

In the United States, the research was conducted by the USAF-directed Operational Applications Laboratory (AFCRC, ARDC), to monitor a project with the Research Foundation of Ohio State University . Among the more interesting of the research findings was that "higher noise levels do not create confusion, but do intensify those confusions already inherent between

6432-538: The issuance of certificates. There are two types of DARs: manufacturing, and maintenance. Specialized Experience – Amateur-Built and Light-Sport Aircraft DARs Both Manufacturing DARs and Maintenance DARs may be authorized to perform airworthiness certification of light-sport aircraft. DAR qualification criteria and selection procedures for amateur-built and light-sport aircraft airworthiness functions are provided in Order 8100.8. A Continued Airworthiness Notification to

6528-577: The launch or re-entry of commercial space vehicles. Powers over neighboring international waters were delegated to the FAA by authority of the International Civil Aviation Organization . The FAA was created in August ;1958  ( 1958-08 ) as the Federal Aviation Agency, replacing the Civil Aeronautics Administration (CAA). In 1967, the FAA became part of the newly formed U.S. Department of Transportation and

6624-480: The letter names, from the International Civil Aviation Organization (ICAO) and the Deutsches Institut für Normung (DIN). Both authorities indicate that a non-rhotic pronunciation is standard. That of the ICAO, first published in 1950 and reprinted many times without correction (e.g. the error in 'golf'), uses a large number of vowels. For instance, it has six low/central vowels: [ æ ] [

6720-497: The letters C, M, N, U, and X were replaced. The ICAO sent a recording of the new Radiotelephony Spelling Alphabet to all member states in November 1955. The final version given in the table above was implemented by the ICAO on 1 March 1956 , and the ITU adopted it no later than 1959 when they mandated its usage via their official publication, Radio Regulations . Because the ITU governs all international radio communications, it

6816-451: The letters of the Roman alphabet , with the goal that the letters and numbers would be easily distinguishable from one another over radio and telephone. The words were chosen to be accessible to speakers of English, French and Spanish. Some of the code words were changed over time, as they were found to be ineffective in real-life conditions. In 1956, NATO modified the then-current set used by

6912-638: The more desirable lists. A final NDRC list was assembled and recommended to the CCB. After World War II, with many aircraft and ground personnel from the allied armed forces, "Able Baker" was officially adopted for use in international aviation. During the 1946 Second Session of the ICAO Communications Division, the organization adopted the so-called "Able Baker" alphabet that was the 1943 US–UK spelling alphabet. However, many sounds were unique to English, so an alternative "Ana Brazil" alphabet

7008-518: The most successful word for each letter when using "military interphones in the intense noise encountered in modern warfare.". He included lists from the US, Royal Air Force, Royal Navy, British Army, AT&T, Western Union, RCA Communications, and that of the International Telecommunications Convention. According to a report on the subject: The results showed that many of the words in the military lists had

Confusion among words like Delta and Extra , and between Nectar and Victor , or the poor intelligibility of other words during poor receiving conditions were the main problems. Later in 1952, ICAO decided to revisit the alphabet and their research. To identify the deficiencies of the new alphabet, testing was conducted among speakers from 31 nations, principally by

7200-569: The overall budget and submit it to the president. At the same time, a new National Transportation Safety Board took over the Civil Aeronautics Board's (CAB) role of investigating and determining the causes of transportation accidents and making recommendations to the secretary of transportation. CAB was merged into DOT with its responsibilities limited to the regulation of commercial airline routes and fares. The FAA gradually assumed additional functions. The hijacking epidemic of

7296-467: The phonetic alphabet used by the Royal Navy during World War I. At least two of the terms are sometimes still used by UK civilians to spell words over the phone, namely F for Freddie and S for Sugar . To enable the US, UK, and Australian armed forces to communicate during joint operations, in 1943 the CCB (Combined Communications Board; the combination of US and UK upper military commands) modified

7392-429: The post-1969 figures should be equally emphasized. The Radiotelephony Spelling Alphabet is used by the International Civil Aviation Organization for international aircraft communications. The ITU-R Radiotelephony Alphabet is used by the International Maritime Organization for international marine communications. Since "Nectar" was changed to "November" in 1956, the code has been mostly stable. However, there

7488-588: The promotion of aviation safety. The FAA Safety Team, or FAASTeam, works with Volunteers at several levels and promotes safety education and outreach nationwide. On March 18, 2008, the FAA ordered its inspectors to reconfirm that airlines are complying with federal rules after revelations that Southwest Airlines flew dozens of aircraft without certain mandatory inspections. The FAA exercises surprise Red Team drills on national airports annually. On October 31, 2013, after outcry from media outlets, including heavy criticism from Nick Bilton of The New York Times ,

7584-628: The pronunciations published by ICAO and other agencies, and ICAO has apparently conflicting Latin-alphabet and IPA transcriptions. At least some of these differences appear to be typographic errors. In 2022 the Deutsches Institut für Normung (DIN) attempted to resolve these conflicts. For example, they consistently transcribe [a] for what the ICAO had transcribed variously as [a], [aː], [ɑ], [ɑː], [æ], [ə] in IPA and as a, ah, ar, er in orthography. Just as words are spelled out as individual letters, numbers are spelled out as individual digits. That is, 17

7680-406: The proposed new alphabet with changes based on NATO's own research, to become effective on 1 January 1956, but quickly issued a new directive on 1 March 1956 adopting the now official ICAO spelling alphabet, which had changed by one word (November) from NATO's earlier request to ICAO to modify a few words based on US Air Force research. After all of the above study, only the five words representing

7776-409: The rapid speed of the airborne aircraft: mobile phones cannot switch fast enough between cellular towers at an aircraft's high speed. However, the ban is due to potential radio interference with aircraft avionics. If an air carrier provides Wi-Fi service during flight, passengers may use it. Short-range Bluetooth accessories, like wireless keyboards , can also be used. In July 2014, in the wake of

7872-620: The regular English numerals ( zero , one , two , etc., though with some differences in pronunciation), whereas the ITU (beginning on 1 April 1969) and the IMO created compound code words ( nadazero , unaone , bissotwo etc.). In practice the compound words are used very rarely. A spelling alphabet is used to distinguish those parts of a message that contain letters and digits, because the names of many letters sound similar, for instance bee and pee , en and em or ef and ess . The potential for confusion increases if static or other interference

7968-534: The rules were not uniform across the European Union. There were proposals to abandon summer time in Europe from 2021, possibly by moving winter time up by an hour and keeping that time through the year. The following countries and territories regularly use Central European Summer Time: The following countries have also used Central European Summer Time in the past: NATO phonetic alphabet This

8064-515: The same committee sent before a meeting to discuss air traffic control privatization noted a 35-year legacy of failed air traffic control modernization management, including NextGen. The letter said the FAA initially described NextGen as fundamentally transforming how air traffic would be managed. In 2015, however, the National Research Council noted that NextGen, as currently executed, was not broadly transformational and that it

8160-399: The same reason. The code words for digits are their English names, though with their pronunciations modified in the cases of three , four , five , nine and thousand . The code words have been stable since 1956. A 1955 NATO memo stated that: It is known that [the spelling alphabet] has been prepared only after the most exhaustive tests on a scientific basis by several nations. One of

8256-431: The table below. Others are: "colon", "semi-colon", "exclamation mark", "question mark", "apostrophe", "quote", and "unquote". Prior to World War I and the development and widespread adoption of two-way radio that supported voice, telephone spelling alphabets were developed to improve communication on low-quality and long-distance telephone circuits. The first non-military internationally recognized spelling alphabet

8352-409: The war. The application of radar to ATC helped controllers in their drive to keep abreast of the postwar boom in commercial air transportation. In 1946, meanwhile, Congress gave CAA the added task of administering the federal-aid airport program, the first peacetime program of financial assistance aimed exclusively at development of the nation's civil airports. The approaching era of jet travel (and

8448-479: The word "customer" properly applies to the flying public, not those entities regulated by the FAA. The bill died in a Senate committee that year. In September 2009, the FAA administrator issued a directive mandating that the agency use the term "customers" to refer to only the flying public. In 2007, two FAA whistleblowers , inspectors Charalambe "Bobby" Boutris and Douglas E. Peters, alleged that Boutris said he attempted to ground Southwest after finding cracks in

8544-424: The words in question". By early 1956 the ICAO was nearly complete with this research, and published the new official phonetic alphabet in order to account for discrepancies that might arise in communications as a result of multiple alphabet naming systems coexisting in different places and organizations. NATO was in the process of adopting the ICAO spelling alphabet, and apparently felt enough urgency that it adopted

8640-624: Was a former Air Force general and adviser to President Eisenhower . The same year witnessed the birth of the National Aeronautics and Space Administration (NASA), which was created in response to the Soviet Union (USSR) launch of the first manmade satellite. NASA assumed NACA's aeronautical research role. In 1967, a new U.S. Department of Transportation (DOT) combined major federal responsibilities for air and surface transport. The Federal Aviation Agency's name changed to

8736-628: Was adopted by the CCIR (predecessor of the ITU ) during 1927. The experience gained with that alphabet resulted in several changes being made during 1932 by the ITU. The resulting alphabet was adopted by the International Commission for Air Navigation, the predecessor of the ICAO, and was used for civil aviation until World War II . It continued to be used by the IMO until 1965. Throughout World War II, many nations used their own versions of

8832-416: Was also adopted by most radio operators, whether military, civilian, or amateur . It was finally adopted by the IMO in 1965. During 1947 the ITU adopted the compound Latinate prefix-number words ( Nadazero , Unaone , etc.), later adopted by the IMO during 1965. In the official version of the alphabet, two spellings deviate from the English norm: Alfa and Juliett . Alfa is spelled with an f as it

8928-438: Was never any guarantee of a job in the CTI program. In August 2023 The New York Times published an investigative report that showed overworked air traffic controllers at understaffed facilities making errors that resulted in 46 near collisions in the air and on the ground in the month of July alone. A May 2017 letter from staff of the U.S. House of Representatives Committee on Transportation and Infrastructure to members of

9024-754: Was renamed the Federal Aviation Administration. The FAA's roles include: The FAA operates five "lines of business". Their functions are: The FAA is headquartered in Washington, D.C. , and also operates the William J. Hughes Technical Center near Atlantic City, New Jersey , for support and research, and the Mike Monroney Aeronautical Center in Oklahoma City, Oklahoma , for training. The FAA has nine regional administrative offices: The Air Commerce Act of May 20, 1926,

9120-499: Was responsible for ATC, airman and aircraft certification, safety enforcement, and airway development. CAB was entrusted with safety regulation, accident investigation, and economic regulation of the airlines. The CAA was part of the Department of Commerce. The CAB was an independent federal agency. On the eve of America's entry into World War II , CAA began to extend its ATC responsibilities to takeoff and landing operations at airports. This expanded role eventually became permanent after

9216-538: Was used in Latin America. In spite of this, International Air Transport Association (IATA) , recognizing the need for a single universal alphabet, presented a draft alphabet to the ICAO during 1947 that had sounds common to English, French, Spanish and Portuguese. From 1948 to 1949, Jean-Paul Vinay , a professor of linguistics at the Université de Montréal , worked closely with the ICAO to research and develop
