Flight Made Cool And Safe: ADS-B Is Coming!
One of the coolest products in the world is not one that will be available directly to consumers, but it will benefit everyone who travels by plane. The Automatic Dependent Surveillance-Broadcast is that cool product and it is making air travel much safer than it ever has been.
Following the September 11, 2001 attacks in the United States, the woeful state of air traffic technology became public knowledge. For the first time, most people in the United States learned that most of the computer systems that monitored and regulated air traffic control were from the 1950s! The last vacuum tube computers were mass produced in 1962, yet the airline industry continued to use those outdated computers. In 2003, the United States Congress established the Joint Planning and Development Office to revamp the outdated technologies the air traffic industry has been using. The JPDO proposed NextGen and the Automatic Dependent Surveillance-Broadcast system is an integral part of that initiative.
The Automatic Dependent Surveillance-Broadcast system is an innovative tool that works much like GPS. The ADS-B system keeps track of each and every plane outfitted with the system. One impressive leap forward that the ADS-B system makes is that the display for the Automatic Dependent Surveillance-Broadcast includes images of both planes in the air and on the ground. Because the ADS-B system monitors planes still in the terminal, it will help prevent runway conflicts. The other important leap forward that ADS-B includes is an interface that is universal. Unlike previous, radar-based systems that showed air traffic controllers only the airspace around their terminal, with plane positions relative to them, the ADS-B provides universal displays. This means that your departure airport, your destination airport and every airport in between has access to the exact same images and the same training to know how to properly interpret it! The ADS-B comes in two parts, the ADS-B In and the ADS-B Out.
The ADS-B In is a receiver. The Automatic Dependent Surveillance-Broadcast system is a satellite-based network that monitors weather information, geographical locations on the ground and ADS-B Out transmitters. In many ways, the ADS-B system is an airborne computer network, specifically designed for aviation. The ADS-B In system is what pilots use to access the Automatic Dependent Surveillance-Broadcast system. Using ADS-B In, the pilot receives weather information, telemetry on other planes and guidance information.
The ADS-B Out is the transmitter. The ADS-B Out is like a combination of GPS and the plane’s black box. The Automatic Dependent Surveillance-Broadcast Out system transmits all data about the plane and flight from the equipped plane to the ADS-B satellite network.
Australia is, to date, the only nation that has fully upgraded entirely to ADS-B technology. The United States is overhauling its aviation industry and by 2020, the intent is that the United States will be entirely on the Automatic Dependent Surveillance-Broadcast system. Finally, the aviation industry is getting out of the 1950s and into the 21rst Century!
