NASA recently presented the prototype software to FAA
for a tool designed to help air traffic controllers reduce delays.
The software, called the Precision Departure Release Capability (PDRC), has automation features that will help controllers by accelerating the process that determines the time an aircraft can begin taxiing toward a runway. Tests of the software have shown that PDRC could fill up to 80 percent of the slots in the constant overhead stream of air traffic that currently go empty because of timing on the ground.
PDRC provides controllers with the ability to better time the moment they will allow aircraft to depart from the terminal gate.
"We call those 'missed opportunities,' and with PDRC working in concert with other tools the FAA
has available, we hope to better take advantage of all the opportunities to safely make flying more efficient," said John Cavolowsky, director of NASA's Airspace Systems Program.
NASA developed the the PDRC after discovering that aircraft operation often shows uncertainty in precise departure time due to factors such as bad weather. PDRC uses a surface model component that automatically sends information about departure times and departure runway conditions to en route centers, allowing controllers time to react more quickly when conditions change.
FAA did not respond to inquiries about when it would go live with the new software.
