A rainstorm rolled across Phoenix last Friday, and the FAA demonstrated that, if they want to, they can immediately change departure routes. To residents in the historic neighborhoods along Grand Avenue, to the northwest, the early turns provided a much quieter evening, a break from the hell FAA turned on last September 18th. But, to residents a couple miles to the east, the early turns helped them to directly understand why so many in Phoenix are so upset at FAA.
Here are sample modified departures
The departure changes are depicted in the following three screen-captures from FlightAware; orange is the designed NextGen noise-impactful route, and green is the route flown during the weather event.
Normal operations resumed two hours later…
…which begs the question (in the tweet below): if FAA can safely and efficiently modify departing flights to deal with a rainstorm, as they did last Friday, why can’t they modify departing flights to fix the NextGen NOISE STORM they have created?
