WARNING : NEXTGEN / Performance Navigation

This Is NOT A Test

(Special warning for Charlotte, NC; the area experience that generated this article.)

If you live within a thirty mile radius of a major airport. Then you MUST read this! You and your family’s life, home, health, property values, and more are in grave danger from a Federal Aviation Administration (FAA) implementation of an aircraft GPS navigation system called NextGen (aka Performance Navigation). Living in a NextGen corridor is almost impossible; read on.

Dozens of medical studies indicate that exposure to jet noise may contribute to any or all of the following problems. Remember!; these studies were completed BEFORE NextGen was rolled out. NextGen cannot possibly do anything other than act as a multiplier of previous study results:

  1. PTSD – Post Traumatic Stress Syndrome
  2. Increased risk of coronary heart disease over normal rates
    1. 60% in men & 80% in women
  3. Increased risk of diabetes
  4. Increased risk of heart attack
    1. each 10 dB rise in jet noise equals a minimum 3.5% increase in hospital cardiac admissions
  5. Increased risk of severe depression
  6. Damage to children’s cognitive abilities
  7. Damage to or loss of hearing
  8. Sleep deprivation leading to health problems, job disruption or loss, and other symptoms/results
  9. Increased risk of domestic violence
  10. Increased risk of substance abuse
  11. Property value collapse
  12. And more ……..

A NextGen corridor is formed when aircraft use GPS coordinates to fly just like an automobile does on the road.

A highway is a very static route for vehicles; its installed path may change, but very slowly over time and with plenty of advanced notice.

A NextGen corridor however can change from one minute to the next based on the whims of flight traffic control. Imagine the Greek Hydra as a metaphor for NextGen corridors and their unpredictability and lethality. If you’ve lived in the same location for your entire life and never had a jet noise problem; NextGen may have a Hydra heading your way tomorrow. I promise you it’s a bad dream you will never forget. Highway construction includes compensation for those losing property in its path. NextGen gets to destroy you for free.

ANYONE in a thirty mile radius of a NextGen airport can easily become a NextGen victim. Gone are the days of “when you live in line with a runway you will have to tolerate jet noise”. NextGen makes everyone a potential victim. You can become one simply because the airlines woke up one morning and found that a five degree shift of a corridor would save them a penny a gallon on fuel. You can go to bed on Tuesday and wake up on Wednesday and watch your lifestyle destroyed and your property investment cut by 50% or more before the day is out.

And, thirty miles is not an exaggeration. The Charlotte Douglas International Airport has received complaints from as far out as Lincolnton, NC; twenty eight miles.

Another negative aspect of NextGen is that it holds flights at lower altitudes for much longer periods assuring ground dwellers much lengthier experiences of discomfort. Departures have been observed remaining at altitudes of 3 to 4000 feet over Franklin Square in Gastonia, NC; twelve miles from  Charlotte Douglas International Airport. I watch them fly low, slow and level over my home every day now, showing no aspiration for altitude; in a line, one every 30 seconds, for hours on end. From the dawn of time to December 13, 2014 my property had never been disturbed by jet noise; the Hydra is here.

If you don’t want this terror hanging around your neighborhood then now is the time to tell anyone and everyone about this danger. You must stand up now or you’ll have no one else to blame when NextGen takes your life away.

Good luck; beware the Hydra hiding in your local airport.


  • I’m not a Luddite; I work in IT.
  • I’m not against air travel.
  • I think NextGen is a reasonable attempt at improving aviation but it appears to have been developed with a complete disregard to surface dwelling human beings. The airspace belongs to all of us; or at least it should, even though now it appears to be the sole domain of the airline industry and we beneath it are expendable in the face of their profits. Unfortunately the USDOT and the FAA who are supposed to promote the health and wellbeing of the American citizenry first aren’t willing to do so. Neither it seems are the political representatives we send to the legislative branch and President Obama and USDOT Secretary Anthony Foxx are good friends so no help is coming form that quarter either.
  • I’m not an advocate of dismantling NextGen but I am strongly opposed to its disregard for earth’s inhabitants and promote redesign to incorporate measures to safeguard our health and wellbeing here on the ground.

Vision Letter to Secretary of Transportation Anthony Foxx (Zero Response)


Mr. Anthony Foxx

Secretary of Transportation

U.S. Department of Transportation
1200 New Jersey Ave, SE
Washington, DC 20590


Dear Secretary Foxx.



The dumping of jet noise by the FAA and Charlotte Douglas Internal Airport (KCLT) on a, previously near jet noise free, low income, highly senior citizen populated, neighborhood; the Catawba Heights area; a blend of Mount Holly (also greatly affected) and Belmont, NC citizens in Gaston County.



I’m the keyboard behind the @StopCLTNoise account on Twitter. I am also a resident of the Catawba Heights community; sandwiched in between the city limits of Mount Holly and Belmont, NC.

As a direct recipient of the KCLT jet noise assault it is my goal to seek methods whereby our community is returned to its former quiet, peaceful state or negotiate methods of acceptable remediation. I have some suggestions I will detail later in this document describing the means of achieving these goals.

I also wish to state at the outset that the saying “if you live near an airport you’ll hear jet noise” is an undeniable fact. Even truer is that this fact applies most directly to anyone choosing to live directly in-line with the runways of an airport. I see no reason those living to the sides should be overly inconvenienced by it. I’ll detail a solution in a moment.

As previously stated; our area has never been high in jet noise and in the nine years I have lived here, to hear an annoying jet aircraft traversal was an exceedingly rare event. That is one reason I chose this location to build, what I intended to be my retirement – end of life years retirement home. I expect to soon have a dataset resulting from an FAA FOIA request; data necessary to identify the past location of the noise we now endure. Even absent that data I can verify from direct experience that the current noise did not reside here in Catawba Heights and state categorically that there is no good or fair reason it should have moved here. For the record I also expect this data to put paid to the lies foisted on the public by the FAA and US Airways that ‘nothing has changed since 1979’. To make these statements to the public via news media when they know NextGen implementation, happening all around us, is the cause and the changes are real, is inexcusable!

Executive Summary:

There are some problems inherent with NextGen as it applies to KCLT. Lacking inside information it took me a while to identify them, an aviation engineer should have been able to predict them rather easily I think. I’ll never know, nor do I really care, why that did not occur to the designers. One thing is obvious; no one took seriously the nature of the flora, fauna and humans that existed on the surface below their airspace.

  • The KCLT NextGen ‘racetrack’, the stretched, open-ended oval created by arrival streams is too tight. This results in the departure pattern being kept close to the surface out as far as 15 miles or so. This low speed, low altitude departure process is the root of our noise problem. It is also a passenger safety hazard as any pilot knows that speed and altitude is a jet’s best friend. Passenger jets don’t glide and are very hard to recover when low and slow. They’re also not as fuel efficient as they are at high altitude. One could reduce noise by and improve passenger safety by: stretching and widening of the ‘racetrack’.
  • There is a better way:
    • Close the ‘racetrack’ loop.
    • What’s good for arrival merge is good for departure dispersion.

Remediation Options:

The drawing at the end of this document visually describes what I’m about to propose in general terms. I’ll readily admit I am not an aviation design engineer so what I propose is strictly generalized.

A vision for the future of KCLT, ‘General’ Aviation Rules for KCLT Traffic:

  1. Extend a line describing the path of a runway ~25 miles in both directions.
  2. Disallow any arriving or departing jet aircraft to descend below ~10,000’ outside a corridor .5 miles either side of the line.
  3. Discourage any future residential construction within the one mile corridor described in rule 2 for the length required for the entrance or departure of jet aircraft.
  4. Encourage only commercial construction within the one mile corridor described in rule 2 for the length required for the entrance or departure of jet aircraft.

Applicable Notes:

  • This automatically widens the ‘racetrack’ to infinity by limiting passenger jet activity to above 10,000 feet over the vast majority of residents.
  • This automatically closes the racetrack’ loop by creating the opposite of an arrival merge fix; a departure dispersion fix.
  • Utilize as much runway for departures as possible as this gets the aircraft to a departure dispersion fix faster.
  • Generally, don’t let anything below 10,000’ unless it is lined up on the runway to arrive or depart.
  • Obviously rules can be broken for traffic required wave offs, emergencies, etc.
  • Require departure streams to cross above arrival streams
  • In the short term these options would limit noise to properties chosen by its owner to be in line with a runway.
  • In the long term the noise would only affect commercial enterprises that don’t care about the noise.
  • I’d estimate these rules would put the beginning arrival merge and departure dispersal fixes approximately ten miles from the airport.
  • This should be easily adaptable with NextGen.
  • This increases passenger safety.
  • I don’t know if this would work for other airports.
  • Most importantly this would constrict any noise problems to a confined area and promote a future with little need for noise complaints
