Roadmap for NextGen Implementation; More News

Ramon Lopez

The public unveiling of the recommendations of RTCA’s NextGen Mid-Term Implementation Task Force (NextGen TF) took place yesterday in Washington, D.C. at the NowGen NEXT conference sponsored by Aviation Today’s Avionics Magazine and RTCA, the organization that develops consensus-based recommendations for the aviation industry.

The NextGen Task Force was formed in February at FAA’s request to recommend a prioritized list of operational capabilities to achieve Next Generation Air Transportation System (NextGen) efficiencies by 2018.

Senior Federal Aviation Administration (FAA) officials were pleased with the RTCA’s NextGen Implementation Task Force final report, expressing optimism that many if not all of the recommendations can be implemented.

According to Task Force Chair Captain Steve Dickson, SVP Flight Operations at Delta Air Lines, "This report is the product of thousands of hours of time and "sweat equity" invested by nearly 300 dedicated aviation industry stakeholders, all working tirelessly to reach consensus on many thorny issues associated with the transition from the current system to NextGen."

The Task Force recommendations would chart a course to the successful implementation of NextGen.

Over the past seven months, the Task Force developed a short list of actionable operational capability recommendations in five operational areas (surface, runway access, congested metropolitan airspace, cruise and access to the National Airspace System).

Surface operations would encompass improved surveillance, traffic management and situational awareness to reduce tarmac delays, enhancing safety, efficiency and information connectivity. Improvements in runway access would follow at converging, intersecting and closely spaced parallel runways. The Task Force members believe the “blunder distance” separating parallel runway can be reduced with the new air traffic control technologies on the horizon.

The members of the study group also see a pressing need to relieve congestion at major U.S. airports located within metropolitan areas. The idea is to integrate procedures and designs to de-conflict airports and expand the use of terminal separation rules. Cruise separation can be reduced through better communications and improved time-based metering. And collaborative arrival planning could also make airport landings much more efficient. NextGen would also improve NAS access to secondary airports and smaller airfields.

They also included two specific NextGen capabilities (automated data communications and integrated air traffic management). Automated datacom would increase the ability of NAS users to better respond to changing conditions, allowing for tailored arrivals and revised departure clearances while easing weather reroutes. Integrated ATM would offer better solutions for traffic flow problems and improved collaborative air traffic management (C-ATM) automation to negotiate user preferred routes and alternative trajectories.

The Task Force also identified four overarching areas that will affect the successful integration of NextGen capabilities. The overarching recommendations include: providing incentives to operators for equipage (via low-interest loans and/or direct subsidies for equipage); streamlining operational approval and certification (by identifying operational and certification issues early in the process); achieving existing three- and five-mile separation standards; and, establishing mechanisms to continue collaboration in NextGen development and implementation.

The one-day conference featured FAA Administrator Randy Babbitt as the keynote speaker.

“This has been a unique process…The efforts of this group have resulted in a sharpened focus for the way ahead. No matter how you interpret the report or its recommendations, one message comes through with great clarity: Everyone agrees that NextGen can’t come soon enough.
“Just about everyone involved has been struggling to define the future of the National Airspace System. For years, we were criticized for not pinning down requirements…I’m hopeful that the work of the task force will put all of this to rest,” stated Babbitt.

“We need to keep in mind the need for a sense of urgency…I think the task force report puts us in the place we need to be…I’ve flown enough to know that NextGen is a success story waiting to happen. We need to advance well beyond the preliminaries. We as a group need to commit together to giving it the juice it needs. Lest there be any doubt, I’m making that commitment for the FAA right here, right now. And I have the support of the Secretary of Transportation and the President. They want this up and running, and they are fully supportive. The green light can’t get any greener than that,” Babbitt continued.

“The Task Force has forged a consensus across a wide spectrum of users…This is an excellent head start. You’ve given us a short list of recommended operational capabilities. Task Force efforts have provided us with a unique opportunity to align our implementation plan with the desires of the aviation community.

“The report also points to the need for delivering NextGen capabilities where they matter. RNP and RNAV approaches are good. RNP and RNAV approaches in high traffic areas are great. We need to be candid with ourselves. We’ve got a lot of these approaches, but we’ve got a lot of them that aren’t in the right spots.

“For those who worry that the FAA is focusing on near-term expediencies at the expense of longer-term deliverables, let me assure you that is not the case. The focus of the Task Force was maximum benefit from today’s tools. NextGen requires us to forge ahead with delivery of tomorrow’s capabilities and we have every intention of doing that. ADS-B is a case in point. Lessons learned from implementing the recommendations of this task force will help us derive maximum benefit from ADS-B once the supporting infrastructure and standards are in place,” the FAA boss told the conference attendees.
