Air traffic controllers are the people who operate the air traffic control systems to expedite and maintain a safe and orderly flow of air traffic. They apply separation rules to keep aircraft apart from each other in their area of responsibility and move all aircraft safely and efficiently through their assigned sector of airspace. Because controllers have an incredibly large responsibility while on duty, the ATC profession is regarded around the world as one of the most difficult jobs today, and can be notoriously stressful depending on many variables (equipment, configurations, weather, traffic volume, human factors, etc.). Having said this, many controllers would cite high salary, very good employee benefits, autonomy, and flexible hours as major advantages of their job.

Although the media frequently refers to them as air controllers, or flight controllers, most air traffic professionals use the term air traffic controllers. They are also called air traffic control officers (ATCOs), air traffic control specialists, or simply controllers. For a more detailed article on the job itself, please see air traffic control.

Features of the job

Core skills of a controller

Air traffic controllers are generally individuals who are well organized, are quick with numeric computational, have assertive and firm decision making skills, and possess excellent short-term memory abilities. In addition, studies have shown that air traffic controllers generally have a degree of situational awareness that is much higher than the average population. Excellent hearing and speaking skills are a requirement, and trained undergo rigid physical and psychological testing. In addition they are generally assertive but calm under pressure, and they are able to follow and apply rules yet be flexible when necessary. Air traffic controllers must maintain some of the strictest medical and mental requirements for professions; conditions such as diabetes, epilepsy, and heart disease typically disqualify people from the position. Conditions such as hypertension are taken seriously and must be monitored with medical exam. Controllers must take precautions to remain healthy and avoid certain medications that are banned for them. Many drugs approved drugs by the U.S. Food and Drug Administration (FDA) such as SSRI antidepressants are banned. Almost universally, trainee controllers begin work in their twenties and retire in their fifties.

Communication is a vital part of the job: controllers are trained to precisely focus on the exact words pilots and other controllers speak, because a single misunderstanding about an altitude level or runway number for example can have tragic consequences. Controllers communicate with the pilots of aircraft using a push-to-talk radiotelephony system, which has many attendant issues such as the fact only one transmission can be made on a frequency at a time, or transmissions will either merge together or block each other and become unreadable.

Although local languages are sometimes used in ATC communications, the default language of aviation worldwide is English. Controllers who do not speak this as a first language are generally expected to show a certain minimum level of competency with the language.

Teamwork plays a major role in a controller’s job, not only with other controllers and air traffic staff, but with pilots, engineers and managers.

Area or en route

Area controllers are responsible for the safety of aircraft at higher altitudes, in the en route phase of their flight. In most nations they are known as "area" or "en route" controllers. Airspace under the control of Area controllers is split into sectors which are 3D blocks of airspace of defined dimensions. Each sector will be managed by at least one Area controller. This can be done either with or without the use of radar: radar allows a sector to handle much more traffic, however procedural control is used in many areas where traffic levels do not justify radar or the installation of radar is not feasible. In the United States, En-Route controllers work at Air Route Traffic Control Centers or ARTCCs. In other countries, area controllers work in Area Control Centers, controlling high-level en-route aircraft, or Terminal Control Centers, controlling aircraft at medium levels climbing and descending from major groups of the airports.

Aerodrome or Tower

Aerodrome or Tower controllers control aircraft within the immediate vicinity of the airport and use visual observation from the airport tower. The tower's airspace is often a 5 nautical mile radius around the airport, but can vary greatly in size and shape depending on traffic configuration and volume.

The tower positions are typically split into many different positions such as Flight Data/Clearance Delivery, Ground Control, and Local Control (known as Tower by the pilots); at busier facilities, a limited radar approach control position may be needed.

The roles of the positions are;

  • Flight Data/Clearance Delivery: issues IFR flight plan clearances, usually prior to taxi. Unlike the other positions, FD/CD only involves departing aircraft.
  • Ground: issues taxi instructions and authorizes aircraft/vehicle movements on the airport except the active runway(s); controllers are not responsible for aircraft movement on ramps or other designated non-movement areas.
  • Local (Tower): issues takeoff and landing instructions/clearances and authorizes aircraft/vehicle movements on or across runways.
  • Approach: issues instructions to aircraft who are intending to land at the airport. This involves vectoring aircraft in a safe, orderly, and expeditious manner and, if needed, stacking the aircraft at different holding altitudes.

Most countries' armed forces employ air traffic controllers, often in most if not all branches of the forces. Although actual terms vary from country to country, controllers are usually enlisted.

In some countries, such as Brazil, all air traffic control is performed by the military.[2] In other countries, military controllers are responsible solely for military airspace and airbases; civilian controllers maintain airspace for civilian traffic and civilian airports. Historically in most countries this was part of the government and controllers were civil servants. However, many countries have partly or wholly privatized their air traffic control systems; others are looking to do the same.

Education

Civilian Air Traffic Controllers' licensing is standardized by international agreement through ICAO. Many countries have Air Traffic Control schools, academies or colleges, often operated by the incumbent provider of air traffic services in that country, but sometimes privately. These train student controllers from walking in off the street to the standards required to hold an Air Traffic Control license, which will contain one or more Ratings. These are sub-qualifications denoting the air traffic control discipline or disciplines in which the person has been trained. ICAO defines five such ratings: Area (procedural), Area Radar, Approach (procedural), Approach Radar and Aerodrome. In the United States, controllers may train in several similar specialties: Tower, Ground-Controlled Approach (GCA), Terminal Radar Control, or Enroute Control (both radar and non-radar). This phase of training takes between 6 months and several years.

Whenever an air traffic controller is posted to a new unit or starts work on a new sector within a particular unit, they must undergo a period of training regarding the procedures peculiar to that particular unit and/or sector. The majority of this training is done in a live position controlling real aircraft and is termed On the Job Training (OJT), with a fully-qualified and trained mentor or On the Job Training Instructor (OJTI) also 'plugged in' to the sector to give guidance and ready to take over in a second should it become necessary. The length of this phase of training varies from a matter of months to years, depending on the complexity of the sector.

Only once a person has passed all these training stages they will be allowed to control on their possessions.

Work patterns

Typically, controllers work "on position" for 90 to 120 minutes then they get 30 minutes break. Except at quieter airports, Air Traffic Control is a 24 hours, 365-days-a-year job. Therefore controllers usually work rotating shifts, including nights, weekends and public holidays. These are usually set twenty eight days in advance. In many countries the structure of controllers' shift patterns is regulated to allow for adequate time off. In the UK the most common pattern is two mornings, two late afternoons and 2 evenings/nights followed by 4 day break. [3]

Age restrictions

If employed by the FAA, the maximum age one can start training is aged 30 and they must retire at 56 years old. However, if someone had previously held an air traffic controller position such as in the military, they may join up to 31 years of age. [4]

With NATS, the minimum age to start the application and training is 18 while the mandatory retirement age is 60. [5] If an 18 year old joins and is successful then they will have to be posted to an Area course which will ensure they are 21 years old on graduation, thus old enough to hold a radar licence. [6]

Stress

Many countries regulate work hours to ensure that controllers are able to remain focused and effective. Researchcitation needed has shown that when controllers remain ‘in position’ for more than two hours without a break, performance can deteriorate rapidly, even at low traffic levels. Many national regulations therefore require breaks at least every two hours. Additionally, regulations govern shift length, number of night shifts done consecutively, length of time off required between shifts, etc. A typical work week for a controller is an 8 hour day, 5 days per week.

Computerization and the future

See also NextGen

Despite years of effort and the billions of dollars that have been spent on computer software designed to assist air traffic control, success has been largely limited to improving the tools at the disposal of the controllers such as computer-enhanced radar. It is likely that in the next few decades, future technology will make the controller more of system manager overseeing decisions made by automated systems and manually intervening to resolve situations not handled well by the computers, rather than being automated out of existence altogether.

However there are problems envisaged with technology that normally takes the controller out of the decision loop but requires the controller to step back in to control exceptional situations: air traffic control is a skill that has to be kept current by regular practice. This in itself may prove to be the largest stumbling block to the introduction of highly automated air traffic control systems.

Career information

Canada

NAV CANADA, the country's civil air navigation services provider, is a private sector, non-share capital corporation financed through publicly-traded debt. NAV CANADA provides air traffic control, flight information, weather briefings, aeronautical information services, airport advisory services and electronic aids to navigation.

United States

In the U.S., a majority of the air traffic control workforce will retire over the next 10 years. As a result, the Federal Aviation Administration is hiring more than 12,000 new trainees (that take 3–5 years to become fully certified controllers) over the next decade.

There are many avenues to become an Air Traffic Controller. There are 31 CTI (Collegiate Training Initiative) schools around the United States which also provide a college degree in the process.[7] After graduation, personnel are then placed on a list that depicts hiring eligibility. The Federal Aviation Administration then selects personnel from this list and places new hires in a location. The Federal Aviation Administration also hires Air Traffic Controllers who have separated from the United States military. The cut-off age for hire is 31. Finally, the Federal Aviation Administration also hires from the public.

Prior experience or training in air traffic control is not required. However, candidates must have three years of progressively responsible work experience, have completed a full 4-year course of study leading to a bachelor’s degree, or possess an equivalent combination of work experience and college credits. In combining education and experience, 1 year of undergraduate study (30 semester or 45 quarter hours) is equivalent to 9 months of general experience. Certain kinds of aviation experience may be substituted for these requirements.

U.S. citizenship is required. Candidates must be able to speak English clearly enough to be understood over radios, intercoms, and similar communications equipment.

United Kingdom

In the UK there are three main routes to becoming an Air Traffic Controller. One is to join NATS as a trainee controller: this is the only way for people wishing to become Area Controllers. Another is to join a non-NATS airport as an Air Traffic Services Assistant with a view to being sponsored by the employer to become an Air Traffic Controller. The third way is to pay for one's own training to licence level with a view to being hired afterwards (usually by a non-NATS airport).

If a candidate decides to join through NATS, he will begin a rigorous training regime. Once the initial application form is completed and if successful, the candidate will have to complete an online test which is basic checking and mental arithmetic. Stage 1 follows which is a selection of paper and pencil tests. If successful, Stage 2 is a day of computer tests which again further test the candidates skill-set for the job and their aptitude. Stage 3 is the final stage, it involves a thorough interview and a group exercise. If successful then the candidate will go for a medical and the process for security clearance begins. If the candidate gets this far, he represents the top 3% of applicants. [8]

Controllers can earn up to £90,000 per year depending on employer, experience and the unit at which they are employed (the highest salary potential for NATS Controllers is at Swanwick and Heathrow). Controllers employed by NATS, on appointment as an Air Traffic Controller (3rd anniversary of joining NATS) earn between £41,653 - £46,423 plus shift pay of approximately £5,489 (April 2009).[9]
