The U.S. does not yet have a collaborative, integrated air traffic management system that can cope with the coming revolution in propeller craft that will whisk passengers over urban areas, said members of the “Air Traffic Management Modernization” panel June 27 at the 2018 AVIATION Forum in Atlanta.

“The user demands are getting more complex as [unmanned aircraft systems] and now air taxis and urban mobility concepts” want to enter the airspace, said Robert Pearce, acting director of NASA’s Airspace Operations and Safety Program. The FAA’s NextGen air traffic modernization initiative will address that demand, he explained, adding that “our job is to help by laying out that technology baseline.”

“As we go into these new paradigms, we need to bring in a much broader community,” Pearce said, referring to industry participation.

Richard Terry, director of line operations for Delta Airlines, cited “silos” of government responsibilities as a problem.

“We have to cut across them if we’re going to come up with an integrated plan,” he said.

One panelist said the integration problem has affected air traffic controllers, who need decision support tools to cope with expanding air traffic. Those tools “just don’t really exist,” said James Ullmann, director of safety and technology at the National Air Traffic Controllers Association, which represents the interests of controllers. He said the “stovepipes” of responsibility are one factor.

Ullmann cautioned that it’s also the basic infrastructure that must be considered. He made his case by showing photos of old computers and paper flight strips in a control tower.

“Something has to change. We have a lot of concerns,” he said.

Breaking those silos and stovepipes through collaboration will be critical to coping with the growing number and kinds of aircraft expected to maneuver through the National Airspace System, the panelists suggested.

Unmanned aerial systems and urban mobility aircraft are hot topics, but panelists also referred to supersonic jets, hypersonic test aircraft, balloons and spacecraft on their way to and from space.

The need to accelerate innovation and modernization of procedures came up several times in the discussion.

Ravi Chaudhary, director of advanced programs and innovation in the FAA’s Office of Commercial Space Transportation, said last fiscal year the FAA licensed 22 launch and reentry activities. Now, in the third fiscal quarter of 2018, FAA has already surpassed that number.

“We don’t expect that to show any signs of slowing down,” Chaudhary said.

Chaudhary said “regulatory humility” will be required to streamline licensing requirements as the pace of launches and recoveries increases. After the session, he added that “government does not always know best” and that innovations must be made at a faster pace.

Gregory Bowles, vice president for global innovation and policy at the General Aviation Manufacturers Association, expressed frustration about the pace of change in his industry.

“I operate in the [National Airspace System] day in and day out,” he said. “I understand how slowly we implement change.”

Bowles said unmanned aircraft are “knocking on the door, and we haven’t responded quickly enough.” He added that urban air mobility concerns are following close behind.

One panelist gave a specific example of the diversity of aircraft expected to ply the airspace and the complexities that this diversity raises.

Parimal “PK” Kopardeker, a senior technologist at NASA’s Ames Research Center in California, referred to industry plans to fly balloons at about 60,000 feet.

“Clearly what’s interesting there is supersonic [aircraft] operating on fixed trajectory, and the balloons will be lingering around,” he said. “We have models of that” to “keep everything apart and safe” by data sharing.

Joseph Post, deputy director of FAA’s National Airspace Systems Engineering and Integration Office, said safety is not just driven by traffic management. He referred to an accident in New York City involving an aircraft attempting to land on top of a building: “That’s not an air traffic control problem,” he said.

Industry and Commerce Working Toward Safe, Beneficial UAS Traffic Management

by David HodesAerospace America contributing writer

Panelists: Moderator Gretchen West, senior adviser of innovation and technology, Hogan Lovells, and advisory board member, Drone World Expo; Sean Cassidy, director, Strategic Partnerships, Amazon Prime Air; David Famolari, director, Verizon Ventures; R. John Hansman, T. Wilson professor of aeronautics and astronautics and director of the International Center for Air Transportation, Massachusetts Institute of Technology; Parimal H. Kopardekar, manager, Safe Autonomous System Operations Project, and principal investigator, Unmanned Aircraft Systems Traffic Management, NASA’s Ames Research Center; Craig Marcinkowski, director of strategy and business development, Gryphon Sensors; Peng Wei, assistant professor of aerospace engineering, Iowa State University

Managing the airspace traffic for unmanned aerial systems will take a coordinated effort from industry and government to keep the systems flying safely as well as to provide the benefits of such things as package delivery, panelists said June 16 at the 2016 AIAA Demand for Unmanned Symposium in Washington, D.C.

In the panel, “UAS Traffic Management System,” Parimal H. Kopardekar, manager of the Safe Autonomous System Operations Project and a principal investigator for Unmanned Aircraft System Traffic Management at NASA’s Ames Research Center, said the goal of NASA is to safely enable large-scale operations in the National Airspace System.

He said NASA must offer airspace operations guidance and performance roles for UAS operators while getting UAS suppliers to work with regulators.

Sean Cassidy, director of strategic partnerships for Amazon Prime Air, said the concept of operations includes the vehicle.

“You have to have a vehicle with performance levels commensurate with the operations,” he said. “You have to know how it reacts to others in the airspace.”

Good airspace operations, according to Cassidy, means you have to have vehicle-to-vehicle communication and some kind of standardization of controller-to-controller protocols.

“Having independent technology is a good thing in the short term,” he said. “But you need a coherent framework about what [UAS traffic management] means to you.”

Cassidy said Amazon is considering implementing a receiver for drones to land on that is aware of the traffic under 500 feet.

“We don’t have that option for the FAA to take time to develop standards,” he said. “This is the first time where speed is our friend.”

John Hansman, T. Wilson professor of aeronautics and astronautics and director of the International Center for Air Transportation at Massachusetts Institute of Technology, said there is a lot of confusion about what UAS traffic management, or UTM, is.

“There is no real concept of operation yet,” he said.

But one of the basic concepts of UTM, Kopardekaer said, is that we need to understand what is involved in going beyond line of sight.

“You want to know the constraints,” he said. “That is what this traffic management system will do.”

Developers Charged With Making UAS a More Trusted and Autonomous System

Panelists: Moderator I.J. Hudson, former technology reporter, NBC4 Washington (WRC-TV); Brian Argrow, professor of aerospace engineering sciences, University of Colorado; Michael S. Francis, chief advanced programs and senior fellow, United Technologies Research Center; Parimal H. Kopardekar, manager, Safe Autonomous Systems Operations Project, and principal investigator, Unmanned Aerial Systems Traffic Management, NASA’s Ames Research Center; John Langford, chairman and CEO, Aurora Flight Sciences Corp.; Richard Wlezien, professor and Vance and Arlene Coffman endowed department chair in aerospace engineering and director, Iowa Space Grant Consortium, Iowa State University

Getting a more autonomous unmanned aerial system to understand what it needs to do with less human direction and finding ways to control it in the airspace are crucial issues for developers, according to a June 15 panel of experts at the 2016 AIAA Demand for Unmanned Symposium in Washington, D.C.

Sandy Magnus, executive director of AIAA, introduced the panel, “The Changing Face of Aerospace: The Impact of UAS on Aviation,” by pointing out users are helping developers understand what needs to happen in design, presenting a shift in the usual method of product development. Now, she said, it’s up to policymakers and lawmakers to make decisions regarding the limitations of technology and its advantages.

Jay Gundlach, founder and president of Flighthouse Engineering LLC, said that UASs are so early in development that we don’t even know what to call them yet.

Parimal Kopardekar, manager of the Safe Autonomous System Operations Project and principal investigator for NASA’s Unmanned Aerial Systems Traffic Management, said that one of the main principles in drone operations is understanding the value of constraints.

“We are talking about managing traffic that has to be as flexible as possible,” he said. “We will be setting up the rules of the road.”

In terms of education for next-generation UAS developers, Richard Wlezien, the department chair in aerospace engineering and director of the Iowa Space Grant Consortium at Iowa State University, said it has been frustrating because drone flights are too restrictive.

“Imagine training to be a physician and not being allowed in the operating room,” he said. “We have long way to go to open up airspace to students.”

Brian Argrow, professor of aerospace engineering sciences at the University of Colorado, said he sees three growing applications of drones: rescue missions, national security, and climate and weather prediction.

“Agriculture has not been a top application,” he said. “But there is a project underway now about soil moisture management using a small UAS.”

One of the biggest issues panel members discussed was trust.

“As they become more autonomous, software for drones has to have some level of trust that they will make the correct decisions,”Argrow said.

That issue is being worked on now, according to Michael Francis, chief advanced programs and senior fellow at the United Technologies Research Center.

“We want the UAS system to be able to learn,” he said. “That’s the part of the industry that is going to grow, because we need to be able to operate safely under expected contingencies.”

Panelists all agreed standards are needed but cautioned that when they are made, they are hard to change or adjust.

“We need to be careful what we put in place and be careful about the nature of standards and what the intent is,” Kopardekar said. “We need to ask ‘What could it stop in the future?’”
