![]() ![]() The mental strain comes from tracking multiple incoming and outgoing data blocks on a one-dimensional video display unit while envisioning three-dimensional space in the airspace surrounding each aircraft. The data inputs from both radar types must be integrated on the main display of the controller, appended to the aircraft data block, and showing as well the result of another piece of radio equipment that continuously interrogates an onboard IFF/identity module for the aircraft. This is the job of height-finder radar, a different piece of equipment altogether. An ATC must be able to separate two aircraft five miles out but at different altitudes. Radar alone is not enough since this gives the only lateral distance from the airport. Setting aside the less urgent concerns of ground or runway traffic control, the real priority of the entire ATC system is that of preventing mid-air collisions when aircraft are moving at variable heights and speeds of from 110 miles per hour (for single-engine, propeller-driven private aircraft) to supersonic speeds (in the case of multi-engine jumbo jet aircraft). ![]() Through all these, ATCs must pursue efficiency and minimize delays. Applications of Probability Collision AlgorithmsĪn air traffic control system comprises not only the controllers themselves but also the interconnected equipment of radar that tracks aircraft between airports, short-millimeter ground radar for managing those on the ground and moving through the runways, guiding incoming and departing flights through safe pathways and with proper intervals between aircraft, instrument landing systems that guide aircraft at night and during low-visibility weather conditions. As it happens, these are the same air transport hubs that offer the most attractive entry-level pay. Kennedy, La Guardia, Newark Baltimore/Washington International, Ronald Reagan, Dulles, Chicago/O’Hare, and Seattle. The high turnover rate and perennially increasing air traffic mean there are always openings, notably at the country’s busiest airports: New York’s John F. On the other hand, the reason for such a young occupational profile is that the job does get very stressful. Since FAA qualification requirements are fairly modest – a four-year college degree or three years in a medium-responsibility position, attendance at the Air Traffic-Collegiate Training Initiative (AT-CTI) program offered in no fewer than 31 sanctioned schools around the country, and a 12-week entry-level training program – this means that leisure and off-work interests are likely to be the same for men in their twenties and early thirties. Nearly two-thirds have been on the job less than ten years. Since military pay ranges from $21,000 to $85,000 (and that excludes money-saving perks such as base housing), earnings can be satisfactory for one who wants to do his patriotic duty and see the world besides.Īir traffic control is convivial work and congenial for those who grew up in an age of intelligent electronic gaming. So do the Department of Defense for early warning and airborne intruder facilities. The Air Force, Navy, and Army all hire ATC’s for their airbases.
