Aviation Week’s David Esler has a very well-researched and in-depth article about SESAR, the European Union’s version of NextGen. It provides a lot of detail about how the two approaches differ (one example: NextGen implementation is being driven by the federal government, while SESAR is being driven by industry partnerships), and also examines questions of harmonization.
Interestingly, one of the key themes is “who’s further ahead?” See the following excerpt:
[On the topic of] who’s leading the parade toward 21st century ATM reform – both SJU [SESAR Joint Undertaking] and FAA solons diplomatically refused to describe themselves as ahead. Here’s what the SJU’s [Executive Director] Patrick Ky had to say: “We are maybe more advanced in how we want to organize our technical activities, whereas you in the United States are more advanced in the implementation of ADS-B. We have different contexts and different relationships with industry, but I think we are making sure with the FAA that we are moving in the same direction and fully in line with each other’s priorities.”
For the FAA perspective, we interviewed Steve Bradford, chief scientist of architecture and NextGen development. “That’s not accurate at all,” Bradford said when we queried whether the SJU was setting the pace in implementing ATM technology. “I’m not going to say we’re ahead, but we are spending money and have a full ADS-B implementation in progress and will have full service by 2013. And our new automation program, ERAM [En Route Automation Modernization], is ahead of schedule.”
We think any discussion of “who’s further ahead” is a bit like asking who’s winning a marathon at mile marker two.
