Global Air Traffic Management System: Training offers inside look into systems capabilities, progress

  • Published
Every week Capt. Chris Hawkins instructs two to four different pilots in Global Air Traffic Management System, or GATM, upgrade training.

He has to pack his bags, kiss his wife and kids goodbye and prepare himself for yet another trip to Hickam Air Force Base, Hawaii. It’s a tough job, but someone has to do it.

The KC-135 is constantly undergoing upgrades. The latest in a long list of navigational upgrades is the installation of the GATM system found in almost all commercial aircraft.

Captain Hawkins, 911th Air Refueling Squadron here, and Capt. James Wilson, 912th ARS have the unique responsibility of training the rest of the base pilots in the use of new equipment. GATM computer systems, in short enable the pilots to “talk” to air traffic controllers without a radio.

“There are so many aircraft flying right now that radios are becoming increasingly clogged,” said Captain Hawkins.

The remedy – get rid of radios.

GATM is a giant “instant messaging” system. An air traffic controller can now talk to several different aircraft simultaneously; whereas before they could only talk to one aircraft at a time.

The system not only allows controllers and the Tanker Airlift Control Center to better communicate with pilots in the air, it also helps to control air traffic.

“It’s [amazing] how the amount of air traffic has increased in recent years,” said Captain Hawkins.

Due to high operations tempo, more aircraft are being tasked every day to fly numerous hours. But military aircraft aren’t the only ones flying; commercial aircraft have to fly in the same airspace.

“The GATM System helps control and manage that system a little easier,” said Captain Hawkins. “Aircraft need space,” he said. “Increased aircraft means less space for the aircraft to fly in. Since we can’t create more space we have to make the distance between aircraft shorter so more aircraft can fit in the same amount of space. GATM uses computers to regulate and manage the ‘closing of the gap.’”

Right now, a KC-135 needs a certain amount of airspace. With the GATM System, the goal is to have two or three aircraft fit into the same amount of space ordinarily occupied by one aircraft.

The upgrade to the GATM System also lends some subtle aesthetic changes to the aircraft. A GATM-equipped aircraft has an extra monitor on the control panel, more computer systems, antennae, a new transmitter fin on the belly of the aircraft and satellite wires on the top of the aircraft.

It also has a new joystick–like controller on the armrest of the pilot and copilot seats.

“This new controller helps us navigate through all the menus the new system has,” said Capt. Jeff Roper, 911th ARS.

Soon all KC-135s will be upgraded to GATM systems, and all pilots will need training. Pilots are required to get numerous ground hours in the GATM simulator here. Along with the simulator hours they must also attain a week of computer based training on the subject. Pilots have not completed their entire GATM training unless they spend one hour in a data link environment. A data link environment is an environment where the aircraft reports directly to air traffic control through a data link. The closest data link environment is in the Pacific and the closest base in the Pacific is Hickam.

“We spend a lot of time in the air going back and forth to Hawaii,” said Captain Hawkins. “Soon this system will be in all Air Force aircraft. I’m just glad that I can be a part in bringing everyone up to speed.”
