The Single European Sky ATM research program (SESAR), developed to unite all European Union air traffic controllers under one operating system, has announced another move toward implementation, with the recent update of the region’s ATM strategic plan. Updates to the original 2009 plan are designed to deploy necessary ATM technologies and procedures through 2030. The ATM plan has been aligned with International Civil Aviation Organization’s aviation system block upgrades (ASBU) in order to guarantee that all the individual countries’ systems work together effectively. Key features of the update include revised plan performance objectives, detailed roadmaps of required technical changes and timelines, introduction of the “essential operation changes” concept and an explanation of precisely how these changes to SESAR will integrate into the current ICAO framework. Metrics highlighted in the first performance objectives section, for instance, expect SESAR to deliver a 2.8-percent increase in fuel efficiencies, 6 percent cost efficiencies, a 40-percent reduction in accident risks per flight hour and a 27-percent increase in airspace capacity.
