Guest column: Don’t privatize Air Traffic Control Published Feb. 8, 2018 at 09:30PM (Andy Tullis/Bulletin photo) It’s hard to fathom the Washington, D.C., interest in privately contracting the nation’s air traffic control system, operated publicly by the Federal Aviation Administration. Any pilot who flies internationally understands that the system is the envy of the world. It works incredibly well as it is; please don’t fix it. A rigorous air traffic control system provides us with very safe airspace in the United States. Pilots have confidence in the system, and they understand full well that lapses in judgment or procedure will be dealt with directly and effectively by controllers. I know; I got in a spot of trouble with them as a young pilot, and within a day, I was ordered to seek additional training about my responsibilities as a pilot in a busy, urban airspace. FAA-ATC professionals are very effective “air police.” It’s hard to imagine how a private contractor could fill that function. Rent-a-Cop, contracted enforcement rarely works; as a pilot, I don’t want a rent-a-cop writing me traffic tickets. The FAA-ATC is closely aligned with our Defense Department, providing eyes and ears over every square mile of domestic airspace, a vital element of domestic national security. Under a private contractor, that relationship would necessarily be diminished. Here again, why would we risk losing this effective, proven national security partnership? Last year, I flew my plane around the world. I went through Canada (not bad air traffic control, but not as good as ours), Greenland, The United Kingdom, Western Europe, Russia and home. The systems outside of the United States are cumbersome, clunky and expensive to use — and they are largely run by private contractors. They don’t provide the direct style routing that we have become accustomed to in the United States. They are regimented, inflexible and inefficient. Recently, the FAA made a comparative study of American vs. European air traffic systems https://www.faa.gov/air_traffic/publ...rison_2015.pdf .. It’s a dense document, but the upshot is that the complexity of air traffic organizations results in a significantly less efficient delivery of air traffic services — and to commercial travelers, that means delays and traffic hassles. They’ve tried contracting air traffic control in the U.K. and Canada, and both countries had to go back and bail out the contractors through massive fee increases on travelers and from taxpayers. And a U.S. Government Accountability Office report raised issues and doubts about such a massive, complex transition, probably the most important of which is how the highly skilled ATC staff would be split between the public agency and the new private organization. There is nothing to envy about the European air traffic system. The United States has fewer air traffic controllers managing many more types of aircraft, from commercial to private to military. A fourth of their traffic delays are caused by traffic volume, as compared with 3 percent here. Our system handles more traffic, with far less delays, for less money. This is a horrible idea. It would provide perceived benefits to one industry — the commercial airlines (I think it will hurt them, too!) — to the complete detriment of general aviation (everyone else). It’s a solution in search of a problem. The American air traffic control system works incredibly well; it isn’t broken; do us all a favor, please don’t fix it. ------------------------------------------------------------------------ https://www.faa.gov/air_traffic/publ...rison_2015.pdf Produced by: EUROCONTROL on behalf of the European Union FAA Air Traffic Organization System Operations Services Comparison of Air Traffic Management-Related Operational Performance: U.S./Europe August 2016 ABSTRACT This report is the 5th in a series of joint ATM operational performance comparisons between the US and Europe. It represents the 2nd edition under the Memorandum of Cooperationbetween the United States and the European Union. Building on established operational key performance indicators, the goal of the joint study conducted by the Federal Aviation Administration (FAA) and EUROCONTROL on behalf of the European Union is to understand differences between the two ATM systems in order to further optimise ATM performance and to identify best practices for the benefit of the overall air transport system. The analysis is based on a comparable set of data and harmonised assessment techniques for developing reference conditions for assessing ATM performance. Although the US CONUS airspace is 10% smaller than the European airspace, the US controlled approximately 57% more flights operating under Instrument Flight Rules (IFR) with 24% fewer full time Air Traffic Controllers (ATCOs) than in Europe in 2015. US airspace density is, on average, higher and airports tend to be notably larger than in Europe. In terms of traffic evolution, t here was a notable decoupling between the US and Europe in 2 004 when the traffic in Europe continued to grow while US traffic started to decline. The effect of the economic crisis starting in 2008 impacted traffic growth on both sides of the Atlantic .. While traffic in Europe decreased by 3.3%, air t raffic in the US decreased by 9.9% between 2008 and 2015 reaching a low of traffic in 2013. For 2013 - 2015, the US CONUS experienced traffic growth of 1.6% .. While weekly traffic profiles in Europe and the US are similar (lowest level of traffic during weekends), the seas onal variation is higher in Europe. European traffic shows a clear peak during the summer months. Compared to average, traffic in Europe is in summer about 15% higher whereas in the US the seasonal variation is more moderate. At system level, the US has a notably higher share of general aviation than Europe which accounted for 22% and 3.7% of total traffic in 2015, respectively. In order to improve comparability of datasets, the more detailed analyses were limited to controlled flights either originating f rom or arriving at the main 34 US and European airports. The samples are more comparable as this removes a large share of the smaller piston and turboprop aircraft (general aviation traffic), particularly in the US. Air t raffic to or from the mai n 34 airpo rts in Europe and in the US in 2015 represented some 64% of all flights. There are a number of differences between the two systems. In the US, the Air Traffic Control System Command Center - which is the equivalent of Network Manager Operations Centre in Europe, is in a stronger position than its European counterpart with more active involvement of tactically managing traffic on the day of operations. The US also operates with fewer airports applying schedule limitations which may lead to a better util ization of available airport capacity in id eal weather conditions .. The analysis of meteorological reports suggests that weather conditions at the main 34 airports in Europe are , on average, less favourable than in the US. In 2015, 84.5% of the year was spe nt in visual meteorological conditions at the main 34 US airports compared to 77.8% in Europe. Europe shows more airports operating closer to their declared capacity with more IFR flights per active runway. The US operates many airports with complex runwa ys with highly variable capacity and several are operat ing at close to peak capacity. F or airports with more than 3 runways, US declared rates are in general high er than Europe. For Europe, London Heathrow, Frankfurt, and Paris Charles de Gaulle clearly have demand/capacity characteristics comparable to the slot coordinated airports in the US .. Each system has area s that are highly impacted by S pecial Use A irspace (SUA) , o ften due to operations of a military nature. For Europe, SUA permeates all regions and adds complexity in some of the most densely traveled areas of Europe. For the US, those areas are more concentrated, particularly in coastal regions. The impact of SUA on flight efficiency indicators can be clearly seen but its u nique impact is not quantified in this report. Building on established operational key performance indicators , the second part of the comparison report evaluates operational performance in both systems from an airline and from an ANSP point of view. The ai rline perspective evaluates efficiency and predictability compared to published schedules whereas the ANSP perspective provides a more in depth analysis of ATM - related performance by phase of flight compared to an ideal benchmark distance or time .. For the majority of indicators, trends are provided from 2008 to 2015 with a focus on the change in performance from 201 3 to 2015. Punctuality is generally considered to be the industry standard indicator for air transport service quality. The trend in punctua lity was similar in the US and Europe between 2005 and 2009 when both systems reached a comparable level of around 82% of arrivals delayed by 15 minutes or less in 2009. Whereas in the US performance remained stable in 2010, punctuality in Europe degraded to the worst level on record mainly due to weather - related delays (snow, f reezing conditions) and strikes .. From 2010 to 2012, punctuality in Europe improved again and continued to improve in the US. However in 2013 and 2014, whereas punctuality in Europe r emained largely unchanged, punctuality in the US saw a sharp decline. In 2015 both systems reached again a similar performance level due to notable improvements in the US and performance degradation in Europe. In Europe and the US, a clear pattern of summer and winter peaks is visible. Whereas the winter peaks are more the result of weather - related delays at airports, the summer peaks are driven by the higher level of demand and resulting congestion but also by convective weather in the en - route airspa ce in the US and by a lack of en - route capacity in Europe. While the evaluation of air transport performance compared to airline schedules provides valuable first insights, the involvement of many different stakeholders and the inclusion of time buffers in airline schedules limit the analysis from an air traffic management point of view. Hence, the evaluation of ATM - related performance in this comparison aims to better understand and quantify constraints imposed on airspace users through the application of air traffic flow measures and therefore focuses more on the efficiency of operations by phase of flight compared to an unconstrained benchmark distance or time. In order to minimize the effects of ATM system constraints, the US and Europe use a comparabl e methodology to balance demand and capacity. This is accomplished through the application of an “ATFM planning and management” process, which is a collaborative, interactive capacity and airspace planning process, where airport operators, ANSPs, Airspace Users (AUs), military authorities, and other stakeholders work together to improve the performance of the ATM system. ATM - RELATED DEPARTURE RESTRICTIONS (GROUND HOLDING) Ground delays imposed by ATM - related departure restrictions were analysed by constrain ing environment (en - route or airport/terminal) and by causal factor (weather, capacity, etc.). After the poor performance due to weather and strikes in 2010, average ATM - related departure delay in Europe decreased again until 2013. Between 2013 and 2015, total ATM - related ground delays increased in Europe by 43.4% whereas traffic grew by 4.1% during the same time. The US has also shown an improvement since 2008 some of which can be attribut ed to improving weather and declining traffic levels. Between 2013 and 2015, total ATM - related ground delay in the US decreased by 12.7% (mainly due to fewer weather - related delays) with traffic levels increasing by 1 .. 6 % during the same time. In Europe, th e notable performance deterioration between 2013 and 2015 was due to a significant increase in capacity/volume related delays and to a lesser extent due to weather. ATM - related ground delay per flight in Europe (en - route and airport) was lower than in the US in 2015 (1. 3 vs. 1. 6 minutes per flight) but the underlying reasons and the application of ATM - related departure restrictions among facilities differ notably between the two systems. Europe ascribes a greater percentage of delay to en - route facilities ( 43% of total delay in 2015) while in the US the large majority is ascribed to constraints at the airport (82.1% of total delay in 2015). The share of flights affected by ATM - related departure restrictions at origin airports differs considerably between the US and Europe. Despite a reduction from 5.0% of all flights in 2008 to 2.0% in 2015, flights in Europe are still over twice more likely to be held at the gate or on the ground for en - route constraints than in the US where the share of flights affected by ATM - related departure restrictions was 0.8% in 2015. For airport - related ground delays, the percentage of delayed flights at the gate or on the surface is slightly lower in Europe than in the US (2.3% vs. 2.5% in 2015). However, with 51 minutes, the de lay per delayed flight in the US is notably higher than in Europe in 2015 (33 mins). In the US, the airports which make up a large percentage of those delays are airports like New York (LGA), Chicago (ORD), Newark (EWR), San Francisco (SFO), New York (JFK) , and Philadelphia (PHL) which report a large number of hours with demand near or over capacity and have l ower predictability of capacity .. .... |
