Aircraft Noise Abatement: At
Last, Some Progress To Report
By T. Sinclair (Tory) Jacobs
In an effort to focus attention
on the need to accelerate implementation of the Miami International
Airport Noise Abatement Program, Commissioner Jimmy Morales arranged
a meeting chaired by Mayor Alex Penelas with attendance by FAA
and Miami-Dade Aviation Department (MDAD) executives.
The meeting served as a catalyst for both
MDAD and FAA to agree to move forward with the long-awaited test
of Flight Track Management. Targeted to start the week of June
3, 2000, Nighttime, East Flow Departures will be utilized from
both runways in service on due-east flight paths and will be
held on tract until over water before being released for turns
onto course.
Provided this 180-day Flight Tract Management
test goes as anticipated and the concurrent Environmental Assessment
Studies are supportive, as early as May 2001, it may be incrementally
expanded for daytime departures.
Results of the current West Flow Departure
Test should be available in the late spring.
New procedures for arrivals from the water
approach, including designated flight tracts and higher elevations
during the earlier segments of the approach are being promulgated
for late summer start.
Currently, the Control Tower (under FAA)
releases flight control immediately after takeoff, so pilots
fan out toward their ultimate headings. By limiting flight paths
to two designated tracks (for east flow nighttime departures)
over minimum residential areas, and by holding aircraft on course
until over the water, neighborhoods should experience considerably
less noise pollution.
Also, raising the altitude of flights
as they approach and depart Miami International Airport
though causing steeper ascents and descents will lessen
the impact of aircraft noise.
Jeffrey R. Bunting, MDAD's Chief of Aircraft
Noise and Environmental Planning, has been authorized to add
four analysts to his staff to facilitate the ANONS and complaint
programs.
All of these initiatives are encouraging,
however, the pace of progress still frustrates all concerned.
Continued vigilance is in order to ensure that these commitments
and timetables are maintained.

Aircraft Noise Abatement Issues
(Yet again!)
By T. Sinclair (Tory) Jacobs
A recent article from the BHA
News on Aircraft Noise Abatement was forwarded to Miami-Dade
County Manager Merrett Stierheim. He responded with the request
that his letter refuting some of BHA's statements be published
in the BHA News. You'll find
Stierheim's letter along with our latest
resonse below.
We are encouraged to have finally gotten
the County Manager's attention...that is, if we really have his
attention as yet. Often, CEOs don't even read letters, but just
pass them along to appropriate department heads for action, comment
or response...and even when they sign the response, it goes out
unread. Naturally, these busy executive depend on staff. ..they
just cannot stay abreast of all issues under their purview.
We believe that when the top county officials
finally realize what is, or is not, going on at Miami-Dade Aviation
Department, MIA will no longer be the only major U.S. airport
without a Noise Abatement Program in place.
Outrageous, isn't it?

Aircraft Noise Abatement Task
Force Meetings Moved to County Commission Chambers
Thanks to Commissioner Barbara Carey's initiative, the monthly
Aircraft Noise Abatement Task Force Meetings have been moved
from MIA to County Commission Chambers in order to afford improved
public access and participation as well as television coverage
on Channel 34.
The first meeting at the County Commission
Chambers took place on May 26th. Awareness of the impediments
to noise abatement progress were heightened by the presence of
Nancy B. Shelton, FAA Manager, Airspace Branch out of the Atlanta
office that oversees MIA's operations.
Commissioners Jimmy Morales and JL Plummer,
Jr. both were eloquent in their remarks on the critical need
for immediate remedial action.
However, the exchanges between FAA representatives and Miami-Dade
Aviation Department representatives at the meeting and in subsequent
correspondence strongly suggest continuation of delays.
The failure to implement, even on a test
basis, the Chief Pilot's subcommittee noise abatement procedures
is a major disappointment. Many interested parties believe the
recommended procedures can be activated without FAA approval,
at least on an 180-day test basis. The validity of this position
was recently confirmed by the noise abatement official at another
Florida airport, a facility that put in place an aircraft noise
abatement program over 10 years ago. Miami is reported to be
the only major U.S. airport yet to have activated a noise abatement
program.
The Aircraft Noise Abatement Task Force
Meetings at County Commission Chambers are scheduled for 6:00
p.m., the last Wednesday of each month. Check with the Aviation
Department at (305) 876-0569, for schedule changes.

President's Column By T. Sinclair
(Tory) Jacobs
Aircraft Noise Abatement. . .At Last, Progress!
Looks like we're all about to
get on the same page in support of a realistic program to reduce
our exposure to aircraft noise. We sought American Airlines'
help to formulate noise reduction procedures to supplant MIA's
noise measurement program. We were already all too aware of the
problem. . .we are looking for solutions.
American Airlines' recommended program,
which has worked in other communities, includes:
- Departure Flight Track Management with
take-offs to the east to follow expressways 836 and 112.
- Accellerated Climb Profiles so that aircraft
will be higher, sooner.
- Preferential Runway Use to the west when
wind conditions permit.
- Elimination of intersection takeoffs.
These are 24-hour procedures, not just
night hours. Compliance, initially, is voluntary. AA has already
secured commitments for full compliance by carriers responsible
for 87% of the MIA flights. AA hasn't had time to contact the
other 13% as yet. We are indebted to AA for taking the leadership
position.
The airlines are practicing enlightened
self interest. The Accelerated Climb Profiles will use more fuel,
thus add to costs. But the carriers recognize the community's
disenchantment with the lack of progress in establishing an effective
noise reduction program.
The airline industry wants to avoid the
proposed FAR Part 150 Noise Assessment, an expensive study that
would take some five years to complete, during which time local
authorities, airlines, and the air traffic controllers would
loose control to the extent that they could not manage noise
elimination or reduction through voluntary, cooperative efforts.
Plus, the much-needed fourth runway would be delayed for years,
and most probably, permanently eliminated. Also, the FAR Part
150 Study could lead to imposition of huge financial burdens
on Miami-Dade County to cover costs of residence acquisition
and/or sound-insulating programs for tens of thousands of homes
in the noise exposure area.
We now have a promising noise reduction
program that can be put into practice this month! Professionals
in the field believe that we'll immediately be aware of significant
reductions. And, at the end of the six-month test, indicated
changes, if any, can be made.
According to knowledgeable industry executives, FAA approval
is not required. . .just the commitment of the Miami-Dade Aviation
Department.
We have the full support of the City of
Miami Administration and Commission.
Since the Miami City Commission passed
a resolution on January 26th in favor of this program, the Brickell
Area Association, the Brickell Key Master Association, the Downtown
Development Authority and the Executive Committee of the New
World Action Committee of the Greater Miami Chamber of Commerce
have joined the Brickell Homeowners Association in full support
of the program.
Our job now is to insist that our County
Commission and administration get on the same page.
We're ready to help them find the right
page. This is a WIN, WIN program for all!

Aircraft Noise: Residents Urged
To Report Disturbances
In the ongoing battle to control aircraft noise levels, especially
in residential areas like Brickell, Miami International Airport
is setting up a special telephone line for residents to report
disturbances. The line is intended to help airport officials
identify airlines which are not abiding by the recommended noise
abatement procedures.
The Brickell Homeowners Association has
been participating in the monthly meetings of the MIA Noise Abatement
Task Force, comprised of citizens, business executives and airline
and airport officials. The group is working with MIA to address
ways to ensure that airlines comply with recommended procedures.
Much of the control of aircraft noise
has to do with how steep the plane makes its arrivals and departures
and whether it waits to make its turns over water or neighborhoods.
While there are Federal Aviation Association regulations in place,
it often seems to boil down to technique and common courtesy
on the part of the pilot.
Jeff Bunting, who heads the noise abatement
effort at MIA, worked with BHA to install aircraft noise monitoring
devices at The Palace and Bristol Tower earlier this year. These
devices established a baseline noise level with which to compare
over time.
To help in the effort, residents are asked
to report disturbing noise incidents with the following information.
The report can be called in, faxed in, or mailed to Jeff Bunting's
attention. Although the form below need not be used, it covers
the pertinent data Bunting seeks. It isn't expected that all
people will be able to identify the aircraft, but "any kind
of information is helpful," Bunting said.

Column: Rumble Over Miami: AIRCRAFT
"Noise" Intrusion, By Francisco J. Garcia
Few of us who live and/or work
in the City of Miami have not at some time experienced noise
intrusion caused by an aircraft thundering by overhead. Worse
yet, many who work and live in the city are systematically subjected
to these highly disruptive, not-to-mention irritating, incidents.
It doesn't help that aircraft fly-bys are regularly scheduled,
for no closing of windows, no raising the stereo's volume and
no pillow over the head can baffle the annoying vibrations that
shake us about from the inside, out.
Once, while speaking about this very issue
with Captain Edward Ferrer, a seasoned aviator with more than
50 years of military and civilian flight to his credit, I expressed
my astonishment at just how loud departing aircraft noise can
be. He stated matter-of-factly: it's no more than the noise of
a blowtorch as heard through a fan... a million-fold!
No question about it, aircraft fly-bys
are disturbing; their recurrence, trying, and everyone's seeming
inability to do anything about them, downright infuriating. Miami's
residents know this. Miami's businessmen know this. Miami's Planning
and Development Division knows this. More importantly, Miami's
Commissioners know this, they too are residents. Most important
of all, perhaps, is that something can and is being done about
noise intrusion. As always, however, the swiftness of the results
is inversely proportional to the complexity of the issue.
Unfortunately for us all, this is indeed
a very complex issue. An overview of the main factors conspiring
to complicate it may elucidate our path toward a solution. First,
it is important to realize that aircraft noise intrusion is foremost
a Miami issue. Not to imply that other municipalities don't suffer
adverse effects as a result of Miami International Airport's
operations, but none more intensely and none more innocently
than Miami.
None more intensely
Miami happens to abut the Airport in the upwind direction. Aircraft
must takeoff against the prevailing wind and in South Florida
prevailing winds travel in a westerly direction.
Aircraft must therefore takeoff in an
easterly heading. Upon leaving the tarmac, engines roaring in
an effort to gain altitude, departing aircraft rumble over Miami
the first five to six miles of their voyage. It is in these first
crucial moments, while the aircraft must break the gravitational
pull, that the engines are strained to the fullest and are therefore
at their loudest. This fact coupled with the still close proximity
of the craft to the ground in the incipient stages of levitation
accounts for the disproportionate impact borne by Miamians.
None more innocently
This may be a somewhat academic consideration, but in my mind
none too trifle. Miami, as a municipality, clearly predates Miami
International Airport. In fact, it happens to be the only municipality
in South Florida that predates heavier-than-air flight. Much
of
Miami's framework and infrastructure was
certainly present prior to construction of the airport. In contrast,
a significant part of the development in other municipalities
has occurred in spite or perhaps because of the airport's location.
Their complaints seem therefore to have a hollower ring. I won't
dwell much, I would only suggest that some deference is owed
to Miami.
Secondly, there is the issue of jurisdiction
or better stated who can, if they should will it, do something
about aircraft noise intrusion in Miami. The answer to this question
is at the crux of why a solution to this problem is so difficult
to achieve. The ultimate authority to effect substantial change
is essentially three-times removed whence the problem occurs
and three-times disjointed. Federal, regional and county authorities
share operational responsibilities, although the way in which
this unfolds frankly eludes me. Lest it seem I have been remiss
in my research, let me clarify that this shared administration
is no exact science, rather an elusive alchemy.
In the interest of fairness, I will assert
my firm subscription to the principle of checks and balances.
It must be recognized that matters of international, or even
national, commerce and travel should by no means be subject to
the caprices or idiosyncrasies of any one region or municipality.
This justifies federal involvement. I hasten to add, however,
that the interests, especially as pertains to quality of life
of individual citizens, should not be compromised by a bureaucracy
too large to micro-manage any issue. The bottom-line, as I have
come to understand it, lies with the ability of the municipal
(county) authority to powerfully advocate and protect the interests
of its constituency.
Let us further consider that our municipal
airport authority, Dade County Aviation Department (DCAD), must
also look after the gainful and efficient operation of the Airport.
Nor would Miamians settle for less, given the pivotal role the
airport plays in our regional economy. This being the case, the
only sensible and practical solution seems to be to find a means
to abate aircraft noise intrusion to a satisfactory level without
unduly infringing on the safety and efficiency of airport operations.
Sensible and practical, yes...but feasible? Also yes!
The City of Miami Committee for Aircraft
Noise Abatement and the Planning and Development Division have
produced a Noise Mitigation Program which sets forth the means
to accomplish just this objective. Its strategy is simple to
follow and simpler to understand. In a nutshell, three simple
measures would take us the greater part of the way there. They
are:
1) Whenever prevailing winds allow (usually
at nighttime), direct aircraft to takeoff in a westward heading.
This would take aircraft away from Miami instead of toward it
as they takeoff which is, again, when they make the most noise.
Directly west of the airport there is an industrial area and
beyond, the Everglades. Any adverse effect would be minuscule
when contrasted to that suffered daily by countless Miamians.
2) Direct aircraft to maintain takeoff
heading until an altitude of 3,000 ft. is reached. This would
eliminate aircraft maneuvering over populated areas. Reducing
the amount of time spent by the craft over these areas would
result in increased safety and reduced noise intrusion.
3) Direct airlines to adopt the Air Line Pilot's Association
(ALPA) noise abatement takeoff profile. This takeoff procedure
requires the pilot to achieve a safe climbing speed quickly and
maintain constant acceleration until the aircraft travels beyond
audible range. This procedure minimizes the increased noise generation
stage and essentially requires the aircraft to glide noiselessly
upward until it is too distant to be heard. Only at that time
may cruising speed be attained.
Finally, it may please you to know that
Miami-Dade County is in the process of assembling a committee
to study Miami's and other proposals in the interest of understanding
the diverse countywide issues and concerns pertaining to the
Airport's operations and in an effort to enact a master plan
that will allow the Airport to be the good neighbor it can and
should be.
Noise appears in quotation marks because
noise by definition is a disagreeable series of vibrations detectable
by the ear. The infra-sound vibrations produced by aircraft,
are not detectable by the ear and therefore technically not noise
and yet they are possibly the most annoying part of so-called
noise intrusion. The part that causes your windows to rattle.
Francisco J. Garcia, architect and urban
planner, is the Urban Design and Special Projects Coordinator
for the City of Miami Planning and Development Division and a
member of the Miami Committee for Aircraft Noise Abatement.

Airplane Noise: Residents Losing
Sleep Under Loud Planes
Has airplane noise that you hear in your home increased? Are
you being awakened in the middle of the night by planes? Have
to stop telephone conversations? Aren't there regulations about
airplane noise, especially at night?
A return visit to the BHA by Dade County
Aviation staffer Jeff Bunting gave residents several explanations
and somewhat distant hope about airplane noise in the Brickell
Area. Indeed, noise has increased as Miami International Airport
continues to grow in passenger and cargo volume.
The details about the situation and what
can be done get a little confusing, but what is important to
know is this: Residential Brickell is under a flight path taken
by planes using the southern one of two east-west runways at
M.I.A. The Winter 1992 BHA News reported that the Aviation Department
said once a delayed refurbishing project closing the northern
runway was finished, the less noise sensitive northern one would
be used again at night and the southern one over Brickell would
be closed from 10 p.m. to 7 a.m. In 1995 we reported that Jeff
Bunting said a lot of noise abatement boils down to pilot technique
and consideration. He explained how M.I.A. was working with pilots
to get them to fly high over residential neighborhoods and would
be adding shoreline and islands to the radar screen so pilots
could see where they are in relation to neighborhoods. The BHA
also reported in both issues that the elimination of Stage 2
aircraft for the quieter Stage 3 aircraft would be complete by
the year 2000, greatly alleviating the problem.
All Night Long
Closed runway? Nothing doing, Bunting said. "Miami International
is open 24 hours a day." He explained the northern runway
is the preferred runway and air controllers try to direct pilots
over that one. The one over Brickell, however, is longer and
easier to use, especially if the plane is an overloaded cargo
carrier, which Bunting said, is frequently the case. If a pilot
tells the controller, "I want to use the other runway,"
the controller must comply.
What about the campaign to make the pilots
fly higher, make their turns farther out, over water? It seems
that it just hasn't worked so well. There are no fines or penalties
at M.I.A., unlike at other airports, thus no incentive to pilots.
"In Miami we have informal noise abatement procedures,"
Bunting said. "We're looking to formalize them." He
has a plan for consolidating the flight path, which now looks
like a hodgepodge of arcs of every degree from the airport out
to the Atlantic. The proposed plan calls for turns 10 miles out
and at a higher altitude.
But whatever he proposes can't shift the impact on residents
from one neighborhood to another. Not 1.5 decibels higher. The
Aviation Department is purchasing a ground-level microphone-recording
system to measure noise to prove that they're not increasing
in one area too much.
"I can't rob Peter to pay Paul,"
Bunting quipped. That's why he can't move the flight path over
downtown, even though it's virtually shut down at night and void
of people. He has to have the ground readings to prove no one
is adversely impacted.
If the Federal Aviation Administration
approves his plan, it still must be approved by the Metro-Dade
Aviation Committee and the full County Commission body. The Commissioners,
elected by district, will each protect their neighborhoods if
they perceive they'll be adversely impacted, Bunting explained.
"What about the promised newer, less
noisy aircraft?" residents asked. Many said that when they
look out their windows to see what's making the obnoxious noise,
they often see what look to be older aircraft, surely not Stage
3. Bunting explained that the phase out is measured by fleet.
So, an airline might have an adequate percentage of its overall
fleet as Stage 3, but is not obligated to spread them around
airports. All their old planes may be used for cargo going to
and from M.I.A. All the old Stage 2 will be gone, but not until
December 31, 1999.
