Since the 1970s, when the FAA began automating air traffic control, the availability of discrete transponder codes to uniquely identify aircraft has been important. With slightly over 2,000 distinct 4-digit codes available for civilian use, there were plenty of codes to allow every flight in the continental US to have its own code.
By the late 1970s, air traffic had increased so that codes would have to be reused in different parts of the country, and occasionally, a flight would have its code changed due to the code already being in use within the air traffic control center.
By the year 2000, air traffic levels had increased to over 6,000 flights being in the air at any given time, making code reassignments routine and occasionally, flights not being able to receive a discrete code at all.
In 2007, the FAA updated the en-route Host computer software to allow aircraft beacon codes to be assigned based on the flight’s origin and destination as opposed to the origin only. CSSI used simulated annealing to optimize the codes that are allocated to each origin-destination combination. The codes generated through this analysis will be in use in every air traffic control center in 2008 and simulation indicates that code reassignments will decrease by 50% or more.
