Why 40-Year-Old Tech Is Still Running America’s Air Traffic Control

27th February 2015

Read it.

At any given time, around 7,000 aircraft are flying over the United States. For the past 40 years, the same computer system has controlled all that high-altitude traffic—a relic of the 1970s known as Host. The core system predates the advent of the Global Positioning System, so Host uses point-to-point, ground-based radar. Every day, thousands of travelers switch their GPS-enabled smartphones to airplane mode while their flights are guided by technology that predates the Speak & Spell. If you’re reading this at 30,000 feet, relax—Host is still safe, in terms of getting planes from point A to point B. But it’s unbelievably inefficient. It can handle a limited amount of traffic, and controllers can’t see anything outside of their own airspace—when they hand off a plane to a contiguous airspace, it vanishes from their radar.

The FAA knows all that. For 11 years the agency has been limping toward a collection of upgrades called NextGen. At its core is a new computer system that will replace Host and allow any controller, anywhere, to see any plane in US airspace. In theory, this would enable one air traffic control center to take over for another with the flip of a switch, as Howard seemed to believe was already possible. NextGen isn’t vaporware; that core system was live in Chicago and the four adjacent centers when Howard attacked, and this spring it’ll go online in all 20 US centers. But implementation has been a mess, with a cascade of delays, revisions, and unforeseen problems. Air traffic control can’t do anything as sophisticated as Howard thought, and unless something changes about the way the FAA is managing NextGen, it probably never will.

And yet people believe all those movies that show the CIA and other federal agencies with super-tech gear. In their dreams….
