Will FAA and Huerta Say Anything, Do Anything, to Protect THE PEOPLE?

(click on image to hear the Dr. Dao portion of Emil’s podcast )

On a Sunday before Easter, when Dr. David Dao was flying home from LA through O’Hare to Louisville, KY, he became the latest in an endless stream of victims of airline abuse. He was seated on a United feeder (Republic Airlines flight #3411) when the airline decided to bump four passengers, so four extra crew members could fly to Louisville for duty the next day. Dr. Dao, with patients to see on Monday, calmly and firmly refused to surrender his seat. The airline then called in airport security and he was forcibly removed, with his face smashed into a seat-arm, before being dragged off the plane. Dr. Dao, who escaped during the fall of Vietnam as a young adult, lost two teeth. Many passengers used their cellphones to capture shocking video of the entire debacle, and it all went viral.

Appropriately, legal counsel was engaged. A press conference was held on April 13, led by attorney Thomas Demetrio. The video is well worth a listen; here’s an embed, and a couple quotes:

At time 4:11, Demetrio states: “I have concluded the following: that, for a long time, airlines – United in particular – have bullied us. They have treated us less than maybe we deserve.”

At time 4:48, Demetrio continues: “Here’s what we want as a society: we want fairness in how people treat us, we want respect, and we want dignity. That’s it. Not a big deal. But just treat us with respect; make us feel like you really care.”

Fairness. Respect. Dignity.

What happened at Chicago, to Dr. Dao, was horrific. He was maltreated, even to the point of violence. No fairness, no respect, and no dignity. This was a gross failure, made worse by the bumbling of a profit-focused airline CEO, and enabled by a faux-regulator captured to serve only industry.

Yes, we need and deserve fairness, respect, and dignity. But, the same applies not just to our rights as passengers, but also to our rights – and responsibilities – as homeowners and employees (teachers and medical professionals, especially). We all deserve to have our environment respectfully protected, so that our families and those we serve can have the highest possible quality of life. But, today’s U.S. airline industry, collaborating with FAA, has come to a point where they routinely and aggressively abuse people, bullying passengers off flights, and destroying neighborhoods that used to be livable.

This terrible incident has unfolded in no small part because people used everyday technologies to share what the industry works hard to hide. The agency that oversees the industry has thus far said and done nothing to assure us, we are right to be shocked. Right to be shocked about the torture of Dr. Dao to accommodate crew who could have taken a company car or another flight, and right to be shocked by FAA’s wanton abuse of authority to impose NextGen impacts that are destroying neighborhoods… solely to tweak airline profits up a bit.

The balance between commerce and community is lost. It needs to be restored, immediately. If Mr. Huerta is not going to stand up and speak up about Dr. Dao’s abuse, he needs to sit down and let someone else serve THE PEOPLE.

KDCA NextGen Impacts May Trigger Yet One More Legal Action Against FAA

FAA is presently being sued by groups across the nation, due to their botched NextGen implementation. It looks like another lawsuit may be initiated, seeking relief for residents in Bethesda, MD. See the Bethesda Magazine article (archived copy below, in a scrollable PDF).

Essentially, what is happening is FAA is tweaking upward the number of operations handled at Washington National Airport [KDCA], to enable four airlines (American, Delta, JetBlue and Southwest) to schedule heavier arrival and departure pushes. To facilitate this, FAA got Congress to pass legislation in early 2012 that eliminated the requirement to do real environmental assessments (this is the infamous ‘CATEX’ issue; click here to see documentation of a CATEX example impacting residents near LaGuardia).

Using CATEX to approve and implement NextGen procedures has turned out to be a huge failure. The root failure is that FAA’s DNL noise metric does not capture the very real and damaging noise impacts caused by repetitive flights passing one after another at low altitudes, using automation to track the same narrow path. This narrow route concentration is very clearly indicated in the graphics, within the article below. The repetitive noises go on for days and even weeks on end; people suffer sleep loss and elevated blood pressure, and some may be going crazy, but their problems are all dismissed by FAA. Oddly, FAA insists that by averaging those weeks over the entire calendar year, no damages are done ‘on average’. This is sort of a variation of a bad strategy for abating pollution: “the solution to pollution is dilution.”

The graphics in this article appear to depict the pre-NextGen and post-NextGen departure tracks. Montgomery County is concerned about the intense concentration for north flow departures heading northeast to NYC and Boston, etc.; the NextGen RNAV departure begins a right turn over the RNAV fix named ALEEX (Cabin John Parkway and I-495), then passes DOGUE (roughly 2-miles NW of the Mormon Temple), inundating North Bethesda. Similarly, residents in the Fort Hunt neighborhoods of Virginia are impacted, because the new RNAV departure procedure in south flow turns west at lower altitudes, roughly two miles north of Mt. Vernon … instead of climbing another couple miles southbound over the Potomac River. Again, all to save the airlines a smidgeon of money, while shifting a heavier noise and pollutant cost onto previously peaceful residential communities. The people below are frustrated not just because the noise pattern persists for hours on end (and can repeat each day for weeks on end), but also because they are trying to squeeze accountability out of one of the most intransigent and insensitive federal bureaucracies ever to exist: today’s FAA.

The Larger Picture

On a national scale, FAA is facilitating hub concentration (see this aiReform Post). Each of the hub-growth airports is also not just seeing a larger number of flights, but the flights are serving a higher percentage of through-passengers, who never even leave the airport terminal. And, for each of these few growing hub airports, other airports are in sharp decline. So, as KDCA grows, there is a shift of flights away from Washington-Dulles [KIAD] and Baltimore-Washington [KBWI]; Dulles is now down 47% from peak traffic year (2005), and BWI is now down 23% from peak traffic year (2001). This is precisely the problem that is growing at a tiny few other major U.S. hub airports, such as Seattle [KSEA] (where Delta is rapidly expanding its schedule) and at both Kennedy [KJFK] and LaGuardia [KLGA] in the New York City area. The KSEA hub expansion is diminishing Portland [KPDX] (down 31% from peak traffic year 1997) and Salt Lake City [KSLC] (down 30% from peak traffic year 2005). In the NYC area, Southwest is expanding while gutting service at Islip [KISP] (down 48% from peak traffic year 2000) American expansion has all but eliminated the use of Pittsburgh [KPIT] as a hub (down 69% from peak traffic year 1997); Delta expansion has all but eliminated the use of Cincinnati [KCVG] as a major airline hub (down 73% from peak traffic year 2004).

NextGen route concentration, caused by autopilot use of RNAV routes, is a serious impact that FAA chooses to totally ignore. Think about it: wherever you live, chances are that any aircraft flying through is not noticeable so long as it is roughly 2-miles or more away from directly overhead. In the case of Bethesda, the pre-NextGen dispersal of departures meant each resident below was subjected to randomized and irregular noise events; but, post-NextGen, the noise events are concentrated and repetitive, like a Chinese dripping water torture.

Of course, this picture reflects the attitudes and values of our nation in 1860. Today, we have technologies that can benefit us, enhancing quality of life … but only if we manage them intelligently.

Heathrow Airport Pays Guardian to Create ‘News Content’

20170110scp-about-explanation-of-paid-content-produced-by-guardian-labs-theguardian-comOne of the more disgusting details from the U.S. elections this past year was seeing the death of the journalism profession. We learned how the mainstream media no longer does hard research, no longer asks tough questions, but instead exists only to collect money for delivering spin and propaganda services. Not just for companies, but also for political parties. Evidently, propaganda going mainstream is a problem in the UK, too.

Here’s a copy of a tweet by BackOffHeathrow, a longstanding and vocal opponent of Heathrow airport expansion. Just like is happening under NextGen routes near a few major U.S. airports, the people who live east and west of Heathrow’s two runways are having their homes and lives destroyed. Same impacts, too: stress and distraction by repetitive noise interruptions, and compromised health due to elevated air pollutants and chronic sleep loss.


(click on image to view archived copy of this ‘paid content’)

Why so much misery and destruction? Primarily to accommodate air travel by airline passengers from North America, Asia, and Europe. Many people use Heathrow as an entry-exit point for Europe; many of them pass through Heathrow because the major airlines decided decades ago that they would use this piece of land for sorting their passengers and maximizing their company profits. By far, the biggest airline at Heathrow is British Airways (BAW, Speedbird). Airline profits are improving, while resident quality of life is steadily declining. No wonder so many people are fighting so hard to stop a third runway at Heathrow.

The Airport Paid For This (with your money)…

Notice who paid for this item that looks like a ‘news article’, which is one of a series of ‘paid content’ by the Guardian Labs team. Yes, Heathrow, the airport authority. Where do they get money to buy these services? From the passengers who fly through Heathrow. The airport authority, just like the regulator, can skim money off of the process, and evidently has no accountability or restrictions to preempt using that money beyond what is needed to operate the airport. In this example, they use that money to promote the airport’s expansion, and in opposition to the anti-expansion efforts by impacted airport neighbors seeking sleep and other relief. They use that money to create paid content, aka ‘Fake News’.

…And it is Nothing but Spin and Propaganda

This is a full-fledged program. On the upper left of the webpage it says, ‘Heathrow sustainable mobility zone’. Click on this and it opens up a whole new webpage with many more ‘articles’.

Take a close look at the article title: ‘How Air Traffic Controllers are Helping Clean Up Aviation Emissions’. The spin implies new technologies are being used to reduce the environmental impacts of aviation. It is spin partly because the methods listed in the ‘article’ for reducing impacts are nothing new … techniques and technologies that have already been used for decades. But, more critically, the spin flies right past the real elephant in the room: that for each of us, when it comes to generating CO2, hours spent travelling as a commercial air passenger are the worst hours in our life. Frankly, the only way for one individual to do more damage to the atmosphere, more quickly, is either to take up a new hobby setting arson fires, or have too much money to blow and start zipping about in your own private jet.

Obviously, if the aviation stakeholders here (the regulators and airport authorities and airlines) REALLY wanted to reduce aviation emissions, they would do five things:

  1. the regulator would reduce Heathrow arrival rates, and the airlines would agree to alter their schedules accordingly, so that the four holding stacks for Heathrow arrivals, as discussed in the ‘article’,  would never even be needed again;
  2. they would get the airlines to do a much better job filling the seats on their flights (the passenger load factor for British Airways, is barely above 80%, an absurdly low rate of seat occupancy that greatly increases the per passenger carbon emissions);
  3. they would agree to impose uniform fees that disincentivize use of Heathrow as a hub airport, while also encouraging airlines to fly a larger percentage of their passengers on nonstop-direct flights to their final destinations (for example, impose a steep fee for flying through, or impose fees that are directly proportional to the itinerary distance flown);
  4. they would advocate for imposition of a heavy aviation carbon tax (which should also replace most other aviation fees and taxes) so as to disincentivize hub connections that are not efficiently located along the direct route of flight; and,
  5. they would immediately abandon the third runway at Heathrow — this additional runway, and the industry that profits from it, are just further bad investment to accelerate the fossil fuel destruction of our planet.

EPA’s Online Resources


(map and table, showing EPA’s ten administrative regions)

The U.S. Environmental Protection Agency (EPA) was created in 1970 “…for the purpose of protecting human health and the environment by writing and enforcing regulations based on laws passed by Congress.”

The effectiveness of EPA has been questioned by practically everyone; pro-commerce types swear EPA is too onerous, while pro-environment types insist EPA consistently falls short in protecting the environment.

Back in 1970, the year of the first ‘Earth Day’, our Congress was as constructively focused on environmental issues as they have ever been. Sadly, most Congress’s since have served commerce far ahead of people, passing laws, bending rules, and granting targeted exemptions that always further undermine EPA. This includes in the area of aviation impacts. Congress has consistently redistributed authority away from EPA and into FAA, on critical environmental matters including aviation noise and leaded aviation fuel. And, Congress has also consistently federalized authority; they’d rather strip local officials of their basic rights to run their local airports to serve the needs of their local community, and instead give that authority to faceless and unaccountable FAA bureaucrats.

A regulatory agency can be constrained by laws, but the most fundamental power is in information. Thus, even a defanged EPA can empower people, so that each individual can understand environmental impacts and effectively advocate for their family, to protect their environment. EPA can serve us – and they do, with work such as their ‘Citizen Science for Environmental Protection’ Program (selected content copied and archived here). But, and especially in the present political landscape, it is UP TO EACH OF US to do the work beyond the data: we have to take that data, formulate the message, and advocate the change.

So, for example, we can look at reports such as this one, showing diminished air quality and other impacts in the neighborhoods to the north of SeaTac Airport [KSEA]. We can also look at the December 2016 report done by the National Advisory Council for Environmental Policy & Technology, ‘Environmental Protection Belongs to the Public – A Vision for Citizen Science at EPA’.

Where Do We Go Now?

If we take away one lesson from the politics of 2016, it should be this: a Democracy is doomed to fail, where the people are not actively engaged in the decision-making process. We cannot expect to achieve the ideals we want and need as a nation (or as a small, local community), if people do not participate. We cannot be distracted; we cannot be lazy; we must guard against the manipulation of voting data and other forms of election fraud; and, we must not allow the selective disenfranchisement that is happening due to ‘the new Jim Crow’ discriminatory laws. Similarly, we cannot expect to benefit from the sound application of science where many of our elected leaders are collaborating with lobbyists seeking to discredit science; climate change denialism is a good example of this failure.

With that in mind, there is a glimmer of hope for the new administration. The GOP has championed de-federalization and expanded LOCAL authority in all matters. Thus, it is conceivable that we may be surprised; Trump, Ryan, McConnell and others may shrewdly use aviation as an example, demonstrating how to reduce bureaucracy, save money and localize control while de-federalizing the authorities that FAA has increasingly abused.

FAA’s Refusal to Manage Airport Capacity

Satellite-based (aka, NextGen) technologies have been in use for decades, and at most airports they have enabled minimization of distance flown and fuel burned. In fact, at the very few airports where NextGen is failing, the problem is not the technologies: it is too many flights, and FAA’s lazy refusal to impose more restrictive airport flow rates.

If you spend any time studying today’s routes and flight profiles for U.S. commercial passenger flights (and it is REALLY easy to do, with FlightAware, FlightRadar24, and other websites that present FAA’s ATC data), you will see that all flights are already capable of and actually flying optimized routes: long, direct flights from origin airport to destination airport, with smooth and continuous climbouts and descents. But, for a small handful of airports, you will also see that ATC ends up creating long conga lines of low, slow and loud arrivals (the Long Island Arc of Doom is the classic example) … simply because there are too many flights arriving in too small a time window.

The root problem is the hub system, and FAA’s policy of enabling undisciplined hub scheduling by the dominant airline. FAA does this to maximize a theoretical number called ‘runway throughput’, and thus to help the airlines to maximize their profits. In simplest terms, a hub airline can tweak their profits upward a percentage point or two, if they can process say a dozen simultaneous arrivals, sorting the passengers quickly between gates, then send all those flights outbound at exactly the same moment.

Obviously, this is only theoretically possible. Because of limited runway capacity, each arrival and each departure needs roughly a one-minute window where the runway is theirs alone, so the scheduled ‘banks’ of a dozen ‘simultaneous arrivals’ and ‘simultaneous departures’ get spread out over two 12-20 minute windows. To safely handle the arrival banks, ATC has to level off the arrivals and extend the arrival pattern to long final legs, spacing the flights at roughly one-minute intervals; to process the departure banks, ATC issues immediate turns on departure (with terrible impacts in places like Phoenix), so that takeoff clearances can be issued in rapid succession.

The reality that FAA and Bill Shuster refuse to accept is this: runway capacity is limited, and we can pretend to be creating new technological solutions, but so long as there are only so many arrivals that a key hub airport can handle per hour, it is folly for FAA to let hub airlines schedule in excess. It only guarantees delays, which then cascade into other airports that otherwise would never see delays. Also, it is important to note that hourly flow rates do not address the problem. Delays happen every time, when just two arrivals aim to use one runway at the same minute. So, if FAA is to work with the airlines to design delay-free arrivals, the schedule needs to look at small time increments, even how many arrivals every 5-minutes. Fortunately, this finer data granularity is easily studied with todays digital processing capabilities.

The solution is obvious: we need Congress to change the laws, so as to disincentivize excessive hub scheduling; and, we need FAA to aggressively restrict airport flow rates at key delay-plagued hub airports, so that the conga lines never need to happen.

An Example: Seattle Arrivals

Here’s an example of what happens at an airport, when just one more flight creates enough traffic, to necessitate ATC stretching the arrival pattern. Seattle is a great example, because it is a major hub airport but [KSEA] is far from other major airports, thus flight patterns are not made more complicated by airport proximity issues. The dominant airline is Alaska (including its feeder, Horizon), but Delta began aggressive hub growth in 2012. The airport has triple-parallel north-south runways; a south flow is by far the dominant airport flow configuration. Whenever ATC has enough arrivals to reduce spacing to less than two minutes apart, the arrivals are extended downwind, turning base abeam Ballard (12nm), abeam Northgate Mall (14nm), abeam Edmonds (20nm), or even further north (see this graphic that shows distances on final from the runway approach ends).

The scrollable PDF below has sample arrivals on December 29th, with altitudes added to the screencaps, to illustrate level-offs and descent profiles. Five sample arrivals are included:

  • Horizon #2052 vs Horizon #2162 vs Horizon #2405: all are Dash-8s, from KPDX. Horizon #2052 has no traffic and is able to use the preferred noise abatement arrival route over Elliott Bay; the other two flights both have to extend to well north of Green Lake, including a long level-off at 4,000ft.
  • Alaska #449 vs Alaska #479: both are from KLAX. Alaska #449 has no traffic and is able to use the preferred noise abatement arrival route over Elliott Bay; Alaska #479 has to extend to well north of Green Lake, including a long level-off at 3,800ft, starting to the west of Alki Point.

One Table Shows the Reality of NextGen

Here’s some data to ponder as we start into a new year: a table, showing commercial operations at each of FAA’s OEP-35 airports, from 2007 onward.

Focus first on the pink column, three columns from the right edge; the airports are ranked in descending order, by the percent decline in annual operations, comparing 2015 with 2007.

Note that the largest declines, at Cincinnati [KCVG], Cleveland [KCLE], and Memphis [KMEM] are huge: down 61%, 53%, and 43% respectively. Note also, the declines are even larger when you compare Total Annual Operations in 2015 vs the various historic peak years for each OEP-35 airport, in the two columns on the far right; for these figures (which include general aviation and military operations data), all airports have declined, ranging from 74% to 2% and averaging 24%.

Click on the image below for a scrollable view; the PDF file may be downloaded.

Three facts stand out from this table, and they all strongly contradict the sales pitches that FAA and industry have been collaborating on the past few years:

  1. Note the bright green line across the table. Just under it are five airports: Charlotte [KCLT], Reagan National [KDCA], Miami [KMIA], Seattle [KSEA] and San Francisco [KSFO]. These are the only five of the OEP-35 airports that recorded an increase in commercial operations from 2007 to 2015; i.e., 6 out of 7 OEP airports SLOWED substantially while the national population grew.
  2. The airport identifiers marked in a dark-red background color are the airports that in 2016 had extensive noise complaint histories (documented online, and in the mainstream media) related to route concentrations under NextGen. Routinely, FAA has imposed these routes without adequate public review, abusing the ‘categorical exclusion’ process. Numerous legal actions have resulted.
  3. For all OEP-35 airports combined, commercial operations have steadily declined 11% from 2007 to 2015, nearly every year. This is industry contraction. And furthermore, the vast majority of U.S. commercial airports peaked in the 1990s, some more than two decades ago!

WIth the new year, we’ll see a new adminstration and changes at FAA and DoT. Don’t be fooled by the impending onslaught of yet another round of propaganda. The U.S. NAS is operating at far below historic peaks and continuing to trend downward. Growth is rare, and limited to key airports where airlines are concentrating flights into superhubs that severely impact local quality of life. The only true beneficiaries of NextGen and ATC privatization are industry stakeholders (especially the airline CEOs, FAA officials, lobbyists, and manufacturers, plus a few elected officials), who will narrowly share the profits while completely ignoring the larger environmental costs.

We don’t need oversold technology fixes pitching RNAV and RNP solutions that have been used for decades; technologies that could and would serve us all beautifully, if FAA would assert its authority with balance, and manage capacity at the largest U.S. hub airports. We need airports to serve communities while being truly environmentally responsible. And for that to happen, we need a new era of transparency and accountability at FAA. We need reform.

[KORD]: Safety is Losing Out with the O’Hare Modernization Plan

One week ago, United 441 departed Orlando [KMCO] late in the day on a scheduled trip to O’Hare [KORD]. The flight history was normal up until the last moment, when the Boeing 757 slid off the edge of the runway and ended up in the mud at 12:53AM. FlightAware shows the flight made it to the gate two hours later.

It turns out, the flight was cleared to land on Runway 4L at a time when runway traction was reduced (after hours of light snow and mist) and the winds were poorly aligned with the runway (nominally a 70-degree crosswind per this official weather: METAR KORD 180651Z 33017G25KT 1SM R10L/P6000FT -SN BR BKN017 OVC043 M08/M11 A2994 RMK AO2 PK WND 33029/0618).

A group in the Chicago area, FAiR.org, issued this press release, making some very credible points. It appears that, in the mad rush to spend billions replacing the O’Hare runway system with a gazillion east-west runways, the busiest commercial airport in the world is losing its capacity to offer runways aligned with the wind, which are needed most during poor weather. The multi-parallel runways, and the NextGen reliance on automation (in the tower, and on the flight deck), are increasing runway throughput but decreasing safety margins.

Click on the image below for a scrollable view; the PDF file may be downloaded.

And what is driving all of this? The desire to be the world’s number one airport, in terms of operations per year. For a few years, Atlanta [KATL] took that title away from O’Hare. Atlanta operates using a set of five parallel east-west runways. Atlanta is Delta’s superHub, and an enormous fraction (well over half?) of arriving passengers never leave the airport… they sit and wait enjoying the comfortable seatpitch on the same plane, or they walk to another gate and depart on a different flight.

FAA is collaborating with the airlines with the same business plan at O’Hare, which is a superHub for both United and American. The safety consequences are not insignificant, but there are environmental impacts, too. Here’s two serious environmental problems with these superHubs:

  1. when a huge portion of arriving passengers are using the airport only as a connecting point, the number of flights in and out of the airport each day far surpasses what is needed to serve the actual community. So, you end up with double, triple, or more flights per hour as are needed. Under NextGen, some neighborhoods like Bensenville are inundated with nonstop noise related to the superHub airport.
  2. the carbon footprint for each passenger is greatly increased. Essentially, every time a passenger connects at a superHub not on the direct route between origin and destination, it increases miles travelled. It is quite common in the U.S. for airlines to offer discounted airfares to fill seats, so they offer itineraries that add 20% or more to the miles travelled. This translates to that passenger generating a proportional increase in fuel consuming to carry their butt/baggage to their destination. More time, more hassle, more CO2, but too many of us are conditioned to ignore that because we ‘stole a great deal’, saving $20 when we clicked the buy button.

[KSEA]: One Way FAA can Use NextGen to Optimize Noise Mitigation

Here’s a tip for how to very effectively expose FAA’s NextGen failure: study how ATC handles arriving flights during low-traffic time periods. For example, at the SeaTac Airport [KSEA], where Delta’s decision to start up a new hub in 2012 is causing substantial growth in annual airport operations, the arrivals stay busy through most of the day, but there are a few hours each night when you can find only one arrival being worked. So, the question is, what is the shortest arrival routing ATC will issue when working a single, all-alone arrival, and how does that arrival route change with the addition of more arrivals?

When you study the empirical flight data, you quickly find the answers, and they consistently show: FAA’s largest impediment to system efficiency is simply TOO MANY FLIGHTS. In other words, if FAA really cared to optimize safety and efficiency, they would focus on managing capacity, keeping operations per hour below thresholds that precipitate delays and congestion.

Consider a Recent Arrival: United 505 from Denver

One example of this was United 505, which arrived after 2AM on Tuesday, December 20th. First, notice the overall flight on the satellite view below: as has been the case for many decades, they flew a straight line from Denver, with no zig-zags. Notice, too, that the only significant distances were added at Denver and at Seattle, as needed to accomplish transition to and from the enroute portion of the flight.

How Can FAA Better Use the NextGen Technologies?


(VFR sectional with a red curve added, depicting an optimized noise mitigation approach over Puget Sound and Elliott Bay. Crossing altitudes at 8000ft and 3000ft are added, red text on green background.)

The residents of Seattle are lucky to have a large water body that aligns well with their main commercial airport. But, the basic design elements needed to optimize noise mitigation were not fully considered when FAA was selling NextGen. Key design elements should have included:

  1. keep the arrivals high as long as possible. (way back in the 1970s, FAA actually had a noise mitigation program called ‘Keep em High’!)
  2. for the final ten miles, set up each arrival for a continuous rate of descent, optimally at around 300-ft per mile flown. (thus, arrivals should be designed to cross a fix at roughly ten-miles from the runway end, and 3,000ft above airport elevation)
  3. for the distance from 20-miles to 10-miles from the runway end, design a higher rate of descent, perhaps 500-ft per mile flown. (thus, arrivals would descend from 8,000ft above airport elevation to 3,000ft above airport elevation, during this 10-mile portion of the arrival; with this design, commonly used flight automation systems would enable pilots to easily comply with the designed optimized descent profile and route)
  4. plan to have ATC accomplish sequencing, spacing and speed management to the point where the final 20-miles of the approach begins. (in this case, roughly mid-channel over the Vashon ferry route, at an altitude nominally 8,000 feet MSL)

Interestingly, this proposal is quite similar to one of the approaches that FAA designed and implemented, the RNAV (RNP) Z Runway 16R Approach:ksea-20161204cpy-rnav-rnp-z-rwy16r-ifr-plate
For years, in an extended and heavily-coordinated pitch to sell the NextGen program in Seattle, FAA and others pushed the idea that all arrivals from the west side (from California, Oregon, Hawaii, coastal BC & Alaska) would be routed inbound over Elliott Bay during the predominant south flow landings at SeaTac. This was a good idea, but FAA did not go far enough. I.e., when FAA designed this approach procedure, they focused solely on the portion from the middle of Elliott Bay to the runway; they should have also focused on how each flight would get to that point in Elliott Bay (look for ‘SEGAW’ in the plate above). A truly optimized approach would define fixes and precise altitudes, starting between the fix VASHN (on the approach plate above) and the Fauntleroy ferry dock; such an optimized approach would route each arrival over-water and eventually over the vicinity of the stadiums, and would include speed and altitude profiles easily achieved by today’s air carrier fleet. Note that the profile view for the current deficient approach procedure (above) starts at fix WOTIK, which is at a 6-mile final and well south of Spokane Street.

‘NextGen Fixes’ Tend to be Slow, and Tend to Serve to Advance the Propaganda

Thankfully, some progress has been seen for the [NextGen impact case] at [KSFO], but the repetitive noise impact problems persist nationwide, and in fact, appear to be worsening. In almost all cases, the rare ‘NextGen-fixes’ have three key elements:

  1. the NextGen-fixes further crystallize FAA’s ongoing delay tactics; i.e., just getting to the time when an announcement can be made with a new NextGen-fix eats up months and even years. Moreover, the declared ‘solution’ consistently contains absurdly long timelines for each subsequent goal or step.
  2. the NextGen-fixes tend to help the Public nowhere near as much as they serve FAA and the elected officials. The announcements make elected officials look like they are serving their constituents, thus bolstering their incumbency chances … even though these same officials could and should be far MORE aggressive in demanding performance and immediate corrective actions by FAA. And,
  3. the NextGen-fixes continue to sell NextGen as a solution, when in fact it is the problem. I.e., the news releases and other documents are constantly laced with keywords and quoted lines from FAA’s fraudulent NextGen salespitch.

Here’s a short (just over 1-minute) home-video showing and explaining the impacts FAA’s NextGen SERFR arrivals are having on residents between Santa Cruz and San Francisco.

The Impacts of Repetitive Airport Noise: One Man’s Story from Near UK’s Heathrow

Here’s a copy of a Post blogged today by HACAN Clearskies, related to impacts near the London Heathrow Airport. This story is one man’s anonymous experiences. He first believed he would never be bothered by airplane noise, but the persistence eventually led him to anxiety attacks. He is thankful for his dog and having the limited resources to escape, to drive away to a park. But, obviously, people should not have their homes destroyed in the name of air commerce, with assistance from faux-regulators like UK’s CAA and our FAA.
