Parts of Boston are being severely impacted by NextGen, under routes in and out of Logan [KBOS]. Not just by the narrow route concentration FAA is creating in their environmentally destructive application of satellite technologies, but also in the increased hub concentration that FAA is enabling.
In a nutshell, the airlines want to concentrate flights into just a handful of major hubs, but they need FAA’s help to do this. They need FAA to increase ‘runway throughput’, so that the major hub airlines at airports like Boston can add just a few more flights each hour. Of course, the problem is, in their accomodating the airlines, FAA is causing oversaturation of schedules to the point where:
- flows are virtually non-stop for most of the day; and
- the slightest bit of weather or surge of flights creates overload, and ATC works the arrivals into long conga lines – harder and less safe for ATC and flight crews, but also greatly amplifying impacts upon residents below.
JetBlue has a major hub presence at Boston. Not only that, but JetBlue is a major player at two other hub airports where flight overscheduling is destroying communities: LaGuardia [KLGA] and Reagan National [KDCA]. And, JetBlue’s network relies heavily on connecting passengers through these three hub airports.
Also, JetBlue uses social media to pitch their product, to try and encourage more people to take more flights, and more frequently. The JetBlue facebook page solicits comments from viewers, so it makes sense that a viewer in Milton, impacted by the increase in noise and air pollution by JetBlue and other airlines, would offer concerns and make constructive suggestions. This is precisely what was done, when Andy Schmidt initiated a discussion by sending JetBlue a message, on May 30th. After nearly a month of back-and-forth, and with many delays, Andy came to the conclusion that, frankly, “JetBlue doesn’t care.” He then posted a series of four screencaps, documenting the ‘discussion’. Here’s a compilation:

When it comes to environmental responsibility around hub airports, there is a huge vacuum. Neither FAA nor the industry they are supposed to regulate are working to protect communities from noise and air pollutant impacts. It is only about money, these days.
In the example above, Andy shows a great way to nudge the airlines toward becoming responsive and accountable. What is particularly intriguing about this example is that Andy pointed the airline right at a very effective and affordable action that would reap tremendous environmental benefits: the vortex generator. Here are two graphs from a320whine.com:
The red curve shows two spikes, at ~560 and ~620 hertz, which are the infamous ‘A320 whine’. Notice the substantial noise reduction (green curve) at these frequencies, when the VG deflectors are added.
The green shaded area shows noise reduction from red line (an A320 without the VGs) to green line (an A320 with the VGs added). Study this graph carefully; it shows an improvement, but notice, too, zero improvement within the final 12-miles (20-kilometers) of the arrival. Given the cost, this improvement is well worth the money spent, but airlines and FAA will also need to better manage traffic loads, such as by reducing hourly flow rates.
CONCLUSION: This is a good example of how social media can be used constructively, to engage airlines, and hopefully, to nudge them toward becoming more compatible with the communities they impact. And, the vortex generators are a real opportunity for JetBlue to show they care.
Will they? Will JetBlue’s management wake up, so thousands can sleep better?
