Ground traffic management program saves passengers and airlines time while cutting fuel costs
The focus of Airspace Technology Demonstration 2 was IADS, a software that coordinates flight schedules between the ramp, tower, terminal, and center control facilities. This visual representation of data helps minimize delays on the ground.If every commuter drove the same few roads at the same time every day, the traffic would be unbearable. That’s exactly what’s happening in the skies above the nation, known as national airspace .
Holding airplanes at the gate until just before takeoff allows them to run on power supplied by the airport. American Airlines saved millions of gallons of fuel and maintenance costs and tons of harmful emissions by only running engines when arriving at and leaving the gate.Working with the Federal Aviation Administration , commercial airlines, and airports, NASA developed and tested a new program to manage airport traffic on the ground – the Integrated Arrival, Departure, and Surface system.
Before IADS, one challenge the airport faced was a technology mismatch – the airport’s control tower used one software program and ground management used a different one, with no way to integrate them. A phone call was the most common way to notify each other about changes or problems. With approximately 115 aircraft on the ground at any time, a delay in communication could create complications.
