Career As A Air Traffic Controller
Air traffic controllers are people trained to maintain the safe, orderly and expeditious flow of air traffic in the global air traffic control system. The position of air traffic controller is one that requires highly specialized knowledge, skills, and abilities. Controllers apply separation rules to keep aircraft at a safe distance from each other in their area of responsibility and move all aircraft safely and efficiently through their assigned sector of airspace, as well as on the ground. Because controllers have an incredibly large responsibility while on duty (often in aviation, "on position") and make countless split-second decisions on a daily basis, the ATC profession is consistently regarded around the world as one of the most mentally challenging careers, and can be notoriously stressful depending on many variables (equipment, configurations, weather, traffic volume, human factors, etc.). Many controllers, however, would cite high salaries and a very large, unique, and privileged degree of autonomy as major advantages of their jobs.
Although the media in the United States 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 computations and mathematics, have assertive and firm decision making skills, are able to maintain their cool and composure under pressure, and possess an excellent short-term memory. Through numerous studies throughout the decades, it has been successfully demonstrated that traffic controllers usually have a superior visual memory, and in addition, studies have shown that air traffic controllers generally have a degree of situational awareness that is significantly better than the population average. In games involving short-term memory, peer-induced stresses, and real-time risk analysis, air traffic control specialists scored better than the control group in every experiment. Excellent hearing and speaking skills are a requirement, and trainees undergo rigorous physical and psychological testing.
Moreover, the position of the air traffic controller requires some of the strictest medical and mental requirements for any profession in the world; conditions such as diabetes, epilepsy, heart disease, and many mental disorders (e.g., clinical depression, ADHD, bipolar disorder, a history of drug abuse) almost always disqualify people from obtaining medical certification from the overseeing aviation authority. Almost universally, controllers are subjected to rigid medical and mental exams to ensure safety in the air traffic system. In the United States, for example, all air traffic controllers are required to take and pass a Minnesota Multiphasic Personality Inventory before being hired by the Federal Aviation Administration. Conditions such as hypertension, while not disqualifying, are taken seriously and must be monitored with medical examinations by certified doctors. Controllers must take precautions to remain healthy and avoid certain medications that are banned for them. Many drugs approved by the U.S. Food and Drug Administration (FDA) such as SSRI antidepressants and benzodiazapines, 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 focus on the exact words that pilots and other controllers speak, because a single misunderstanding about altitude levels or runway numbers 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 that only one transmission can be made on a frequency at a time and can either merge or block each other and become unintelligible.
Although local languages are used in ATC communications, the default language of aviation worldwide is English. Controllers who do not speak English 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. Area controllers are responsible for specific sectors of 3D blocks of airspace with defined dimensions. Each sector is managed by at least one Area controller. This can be done 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, which control aircraft at climbing and descending altitudes 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 towers airspace is often a 5-nautical-mile (9.3 km) 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;
1. Flight Data/Clearance Delivery: Issues IFR flight plan clearances, obtains squawk codes for vfr aircraft, helps with coordination for GC/LC, and cuts the ATIS (weather). FD/CD is commonly known in the profession as the secretary of the tower.
2. 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.
3. Local (Tower): Issues takeoff and landing instructions/clearances and authorizes aircraft/vehicle movements on or across runways.
4. 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, all air traffic control is performed by the military.In other countries, military controllers are responsiblesolely 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 En route 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 into the position 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 a position alone.
Work patterns
Typically, controllers work "on position" for 90 to 120 minutes followed by a 30-minute break. Except at quieter airports, Air Traffic Control is a 24-hour, 365-day-a-year job where controllers usually work rotating shifts, including nights, weekends and public holidays. These are usually set 28 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 two evenings/nights followed by four-day break.Age restrictions If employed by the FAA, the latest one can start training is usually age 30, and retirement is mandatory at 56 years of age. However, retired military air traffic controllers may qualify for appointment after reaching 31 years of age.
With NATS, the minimum age to start the application and training is 18 while the mandatory retirement age is 60.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.
Stress
Many countries regulate work hours to ensure that controllers are able to remain focused and effective. Research[citation 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. A "deal" is the term used for any situation where an airplane comes inappropriately close (either horizontally or vertically) to another plane or to a ground vehicle.
Computerization and the future
Despite years of effort and billions of dollars 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 a systems 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.
User acceptance or willingness to use such technology is another important consideration air service providers need to consider prior to implementing any new technology. In a recent study with over 500 air traffic controllers from around the world, Bekier and colleagues found that once the locus of decision-making shifts from the air traffic controller, support for the technology dramatically decreases. Unsurprisingly, they also found that air traffic controllers enjoy the core tasks of their role: namely, conflict detection and resolution.
