This Post looks at data in two online documents, presenting further evidence of the ‘Greener Skies’ fraud that FAA, Port of Seattle, and industry players are foisting on the Public. For all intents and purposes, this is the same fraud being pushed throughout the U.S., and by industry and Congress as well, under the NextGen label.
The data are at:
- Projected average day fuel burn on approaches, with no change: 2.64M lbs
- Projected average day fuel burn WITH RNAV/RNP changes: 2.61M lbs.
These figures were presented in units (pounds) that make the numbers impressively ‘bigger’, but also make it harder to intuitively comprehend. To correct this, the figures are converted in this table (to gallons, then to annual consumption):
||Fuel burn (lbs)
||Converted to gallons
||Gallons per year
So, the proposal is expected to achieve a savings of 1.6 million gallons annually … at an airport that sold 487.1 million gallons that year. In other words, this proposed savings is less than one third of one percent of total fuel sold at Sea-Tac. Now, to the airlines, this (~0.3%) translates to more profits; indeed, the two dominant players at KSEA, Delta and Alaska, might each save around $1,000,000 per year in fuel. But, the costs shifted onto neighborhoods and health far exceed these added corporate profits.
A little deeper research reveals another interesting fact: the alleged fuel savings of Greener Skies are massively dwarfed by annual increases at an airport scheduling more arrivals than the gates can handle. Here’s the data, from page 18 of the 2016 Annual Report for ‘Sea-Tac Fuel Facilities LLC’, showing year-to-year changes far greater than the comparatively measly 1.6 million gallons saved:
||1.6M as a percentage…
||57.7 (a 12% increase)
||2.8% of increased consumption
||41.5 (an 8% increase)
||3.9% of increased consumption
The improvements are nothing when compared to the consumption growth trend. Here’s a chart showing the trends, in both annual fuel consumption and annual operations: And, here’s an analogy: imagine the public view if we were funding a drug-treatment program that was successfully helping 3% of addicts while the number of addicts was growing at such a huge rate. Would we smile if, for every three treatment successes, there were 97 new addicts? Of course, we would not. Only an idiot (or a con-artist) crows ‘success!’ about a failure.
Three realities stand out from this:
- The enormous sums spent pitching Greener Skies and eventually signing off on the proposal were all framed around being pro-environment. It was a massive marketing/propaganda campaign to get out into the communities, present alleged benefits, pretend to engage people to ‘help’ identify and resolve problems, all while parading the idea that FAA, POS and industry care deeply about the environment, air quality, climate change, etc. And yet, these numbers show clearly: there were to be no meaningful environmental improvements. FAA, POS and industry players all knew this fact, even before the Greener Skies briefings and publications that wrapped up in 2012. They also knew (and still know!) that this was all just a big dog-and-pony show, funded by the people and served onto the people.
- A full five years after the FONSI signoff, FAA’s controllers at Seattle TRACON are not even using the RNP procedure down the center of Elliott Bay that was the key component of Greener Skies, the one element supposed to enable the bulk of the environmental benefits. It is as if the entire Greener Skies public engagement process was just an exercise in propaganda.
- The figures presented in the 2012 Greener Skies EA may not even reflect reality. Look closely. The data source documents used in this Post, when combined, show FAA/POS claimed that 487.1 million gallons of jetfuel were pumped in 2014, while also claiming 141.7 million gallons were consumed by west side arrivals on the short descending flight portions between the arrival gates (HAWKZ to the southwest, and MARNR to the northwest). Carefully note, these estimates were ONLY for west side arrivals, and did not look at fuel consumption for east side arrivals. Now, here’s the problem: these portions of these flights are the most fuel-efficient phases for each flight, and are allegedly flown at or close to engine-idle; these portions also represent a small fraction of total flight distance. And yet, the numbers used to calculate potential fuel savings declare the fuel consumption on these relatively short descending flight segments represent nearly a third of the fuel pumped at Sea-Tac? And, bear in mind, Sea-Tac is a major international hub, serving flights across the Pacific Ocean and to Europe. It defies logic; there is no plausible explanatio. FAA and POS need to confirm the numbers, and they need to explain: how is it that the airlines operating in and out of Sea-Tac can allegedly burn so much fuel on these arrivals yet so little fuel on climbouts and enroute to and from all other airports around the world?
Greener Skies was (and still is) both a fraud and a side-show ‘act’, using erroneous estimates while pretending to create benefits that STILL do not exist! And the impacts, using the questionable numbers provided by PoS/FAA, are astounding: they are saying, in 2014, arrivals to Sea-Tac consumed 2.6 million pounds of jetfuel PER DAY while on approach, creating noise and air pollution that we are all supposed to ignore.
