This Analysis looks at a series of arrivals to Logan [KBOS], the commercial hub airport in Boston. A Milton resident had posted the above image at Save Milton Skies on Facebook, so aiREFORM went to FlightAware and compiled a collection of screen captures for this unusually messed up arrival flow. The images are presented in a scrollable PDF.
There are 16 arrivals in 27 minutes; that equates to 9 arrivals per 15-minutes, or an average spacing of 1.7-minutes between flights. This is a rate that should be easily achieved, even if all flights were being routed to a single runway. All arrivals (except one) landed on Runway 4L; the one exception was a Boeing 787-900 arriving from London, that apparently needed a longer runway. Runway 4R was unavailable – NOTAM’d closed for a month of maintenance work.
Between this and other MHFC examples, and the many lawsuits against FAA precipitated by NextGen implementation, sometimes it feels as though FAA is intentionally doing a poor job. If FAA fails enough, do they increase the likelihood of Shuster pushing through legislation that takes ATC out of FAA and makes it a private corporate entity? Would ATC privatization actually reward FAA personnel, who would still collect the federal pensions they earned, but would also be able to operate with even more opacity and without Congressional oversight?

How can FAA prevent such inefficiencies?
- Spend more effort managing arrival flows, and implement lower arrival rates.
- Encourage airport authorities to impose airport fees that disincentivize hubbing.
- Pressure the airlines to schedule fewer flights and user larger seat capacities; the nostalgia value of 10-seaters to/from Nantucket, Martha’s Vineyard and Hagerstown are not worth the environmental costs they help create.
Each of these proposals would improve both safety and efficiency.
