8 Secrets of Air Traffic Controllers
Pilots and flight attendants are key to making air travel safe, but there's a less-visible group of people who are just as essential—air traffic controllers. The Federal Aviation Administration (FAA) employs more than 14,000 of them to choreograph the flow of airplanes on the ground and in the sky, whether that means using radar and other tools to direct aircraft at take off, communicating with pilots about flight paths and weather, or helping pilots land their planes safely. Take a look at these secrets of air traffic controllers to learn about their unique lingo, high degree of job stress, and occasional UFO sighting.
1. MANY OF THEM DON’T WORK AT AIRPORTS.
When you imagine an air traffic controller, you probably envision someone working in a tall glass tower at an airport. However, many controllers toil at either a Terminal Radar Approach Control (TRACON) facility or at a route center, which may be located far away from airports.
According to air traffic controller Chris Solomon, who controls planes for the military, controllers in each of the three types of facilities have different responsibilities. “The typical tower controllers get the planes from the gate to the runway and then airborne to within five or so miles of an airport. The aircraft then becomes under the control of the approach controllers [TRACON],” he tells the website Art of Manliness.
These TRACON controllers usually control the plane during its ascent and descent from the airport. When aircraft reach an altitude above 18,000 feet, the route center controller takes over, using radar to guide aircraft at cruising altitudes until the plane begins its descent. Then the approach controller takes the reins, followed by a tower controller who guides the plane’s landing.
2. AGE IS A MAJOR FACTOR.
Some air traffic controllers begin their careers in the military, while others apply to the FAA’s Air Traffic Control Academy. But no matter how they enter the profession, they must have good vision, a sharp mind, and the ability to think quickly and clearly under pressure. The FAA requires that applicants be 30 years old or younger when they apply to the job, and controllers must retire at age 56, before most of them experience any age-related mental decline.
3. THEY HAVE THEIR OWN BIBLE AND THEIR OWN LINGO.
Pilots and air traffic controllers around the world must speak English to communicate (it's required by the International Civil Aviation Organization), but they also have their own flight-related language. This phonetic alphabetic and numerical system, which replaces letters (A to Z) and numbers (zero to nine) with code words, minimizes confusion and misunderstandings between air traffic controllers and pilots.
For example, controllers say “bravo” instead of the letter “B,” “Charlie” instead of the letter “C,” and “niner” instead of the number “nine.” (Theories explaining the origin of the code word “niner” differ, but aircraft enthusiasts speculate that the extra syllable differentiates it from the German word for “no” or distinguishes it from the pronunciation of the number “five.”) Air traffic controllers also have their own slang and, for instance, use the phrase “souls on board” to refer to the number of people on a plane.
The phonetic system is spelled out in detail in the FAA Order 7110.65 manual [PDF], along with other key code words, phrases, and procedures. Controllers call the manual their "bible," study it during training, and review it regularly to keep apprised of any updates and additions.
4. PILOTS WITH HEAVY ACCENTS FRUSTRATE THEM.
Although English is the official language of aviation, not all pilots speak it well. Air traffic controller Brandon Miller, who works for Potomac Terminal Radar Approach Control (TRACON) in northern Virginia, tells Mental Floss that it can be difficult to communicate with foreign pilots. “However, we are in the business of communication,” he says, explaining that learning to solve potential communication issues is part of their training. When talking to a pilot who has a heavy accent, controllers may speak more slowly, enunciate words more dramatically, and try to avoid changing routes as much as possible.
Stephen, an air traffic controller with the FAA, echoes Miller’s point. “We mainly just bitch amongst ourselves, say things very slowly, and do the best we can” when dealing with pilots who have heavy accents, he writes on Reddit.
5. THEY ALTERNATE BETWEEN STRESS AND BOREDOM.
Because they’re responsible for thousands of lives 24 hours a day, 365 days a year, most air traffic controllers experience a high level of job-related stress. “We often miss birthdays, we work on holidays and weekends, and often operate on alternative sleep cycles,” Miller explains. Staying focused is essential, especially during times of busy traffic and bad weather, so most air traffic controllers take a break every hour or two, depending on the rules at their facility.
According to Miller, the diversity of tasks in his work day keeps his job challenging. At any given time, he may be directing Air Force One or other VIPs (from our country or a foreign one), sequencing commercial passenger jets into a variety of airports in the Washington, D.C. area, assisting police or paramedic helicopters, expediting military fighters and military transport planes, or looking for suspicious aircraft in the Washington, D.C. Special Flight Rules Area.
On the other hand, graveyard shifts and periods with less traffic can be tedious and dull. “Hours and hours of boredom combined with moments of sheer terror, as we like to say,” Stephen told Reddit. “But if you like the challenge and want to be where the action is, it's a great job!”
6. THEY’RE PROBABLY OVERWORKED.
In a 2011 article for The Daily Beast, Bob Richards, who worked as an air traffic controller at Chicago O’Hare International Airport for more than two decades, describes his job as “thrilling, fulfilling, and utterly exhausting.” Richards notes that four of his coworkers died of sudden cardiac death, two died of pancreatic cancer, and many others suffered from stress-related gastrointestinal illnesses. In his early 40s, Richards himself suffered from atrial fibrillation, which eventually progressed into congestive heart failure.
A secret study conducted by NASA in 2011 found that almost one-fifth of controllers made significant errors, partly due to chronic fatigue caused by their lack of sleep and busy shift schedules. To combat fatigue and address controllers who were allegedly asleep on the job, the FAA issued a series of new rules that increase the mandatory time between controllers’ shifts.
7. UFO SPOTTINGS DEFINITELY HAPPEN.
During the course of their careers, most air traffic controllers have personally spotted (or have a coworker who has spotted) some sort of unidentified flying object. UFO sightings are more common at night, when air traffic controllers may see an unexplained blinking light that doesn’t appear to be coming from an aircraft. But strange sightings aren't necessarily alien life forms—radar is so sensitive that it may pick up items such as clouds, a flock of birds, or even a large truck on the ground.
8. THEIR JOB ISN’T GOING ANYWHERE.
Although air traffic controllers rely on radar and other technology to do their jobs, they’re not in danger of technology replacing them any time soon. With so many lives at stake, air traffic control will likely always require humans to ensure that automated systems function properly and technology doesn’t malfunction. And controllers enjoy the sense of satisfaction that comes with using their knowledge and skills to help passengers get from point A to point B safely. “There is a great amount of pride that my coworkers and I take knowing that safety of air traffic control is the last thing on passengers' minds when they get buckled in the airplane,” Miller says.
