JOHN WAYNE AIRPORT NOISE ABATEMENT QUARTERLY REPORTS
SUMMARY:
This report transmits two John Wayne Airport Noise Abatement Quarterly Reports for the
first and second quarters of 2001. The average noise level measured at monitoring station
NMS 10N, located at Columbus Tustin Middle School, slightly increased during first and
second quarters. Average noise levels during both quarters remained below the City,
County, and State criteria of 65 dB Community Noise Equivalent Level (CNEL) for
residential uses.
RECOMMENDATION
Receive and file report.
FISCAL IMPACT
On December 18, 2001, the City Council authorized Wieland Associates to review JWA
Noise Abatement Quarterly Reports. The costs for such reviews are annually included in
the Community Development Department budget.
DISCUSSION
Following the conclusion of each calendar quarter, John Wayne Airport prepares a Noise
Abatement Program Quarterly Report and transmits a copy of the report to the City of
Tustin. Twice a year, the City's consultant prepares a report, which summarizes two
quarterly reports.
Attachment A contains the quarterly reports for the first and second quarters of 2001.
Attachment B contains the summary report prepared by the noise consultant. A brief
overview of the information contained within these attachments is as follows:

Measured Noise Levels
During the first quarter of 2001, the average CNEL at Remote Monitoring Station
(NMS) 10N, located at Columbus Tustin Middle School was 56.9 dB. This is .3 dB
less than the four previous quarters. However, for comparison, the CNEL was .4
dB higher (57.3) during the first quarter of 2000.
During the second quarter of 2001, the average CNEL was 57.5 dB. This is .4 dB
higher than the four previous quarters. For comparison, the CNEL was .5 dB higher
(58.0) during the second quarter of 2000.
All measured noise levels are below the City, County, and State criteria of 65 dB
CNEL for residential areas.
Noise Complaints
During the first quarter of 2001, there were 19 Tustin area complaints compared
with 62 for the same period dudng 2000.
During the second quarter of 2001, there were 17 Tustin area complaints compared
with 34 for the same pedod during 2000.
The number of complaints decreased during the first and second quarters
compared to the same period in 2000. The overall number of complaints during the
second two quarters of 2001 does not appear to correlate with the average
quarterly aircraft CNEL nor with the number of quarterly jet operations at the airport.
The average quarterly aircraft CNEL increased steadily from the fourth quarter of
2000 through the second quarter of 2001, while the number of complaints from
residents of the Tustin area remained relatively steady.
Type and Mix of Aircraft Related to Noise Levels
During the first quarter of 2001, the percentage of quieter Class E aircraft
decreased and the percentage of noisier Class A aircraft increased compared with
the same period in 2000. The average CNEL for the first quarter of 2001 was
slightly lower than the same period dudng 2000.
During the second quarter of 2001, the percentage of quieter Class E aircraft
increased and the percentage of noisier Class A aircraft decreased compared with
the same period in 2000. The average CNEL for the second quarter was lower than
the second quarter of 2000.
JWA Noise Report
February 4, 2002
Page 3
The percentage of quieter Class E aircraft using John Wayne Airport has gradually
increased since the beginning of 2000. This percentage increase in Class E aircraft
was offset by a decrease in the use of the noisier Class A. Based on data from the
first quarter of 2000 through the second quarter of 2001, there does not appear to
be any correlation between the aircraft mix and the average quarterly CNEL at
NMS 10.
Airport Noise Contours
Wieland and Associates, Inc. utilized a noise contour in preparing the attached report.
This noise contour is based on the 2001 contours developed by the noise consultant
for the John Wayne Airport Noise Abatement office. Using this contour, it is estimated
that in 2001 the aircraft-generated CNEL in Tustin ranged from about 59 dB to less
than 55 dB. This is well below the City, County, and State criteria of 65 dB for
residential areas.
Since noise issues are of considerable importance to the City of Tustin, the Community
Development Department will continue to monitor operations at John Wayne Airport
unless otherwise directed by the City Council.

INTRODUCTION
This is the 113th Quarterly Report submitted by the County of Orange in accordance with the
requirements of the California Airport Noise Standards (Califomia Administrative Code Title 21,
Chapter 2.5, SubChapter 6: Division of Aeronautics Noise Standards). Effective January 1,
1986, the criteria for defining "Noise impact Area" was changed from 70 dB to 65 dB
Community Noise Equivalent Level (CNEL). Under this criteria, John Wayne Airport currently
has a "Noise Impact Area."
NOISE IMPACT SUMMARY
Caltrans' Aeronautics Program has established guidelines in the California State Noise Standard
to control residential area noise levels produced by aircraft operations using the State's airports.
Under those guidelines, residential noise sensitive areas exposed to an average Community Noise
Equivalent Level (CNEL) of more than 65 dB define the "Noise Impact Area." John Wayne
Airport uses ten permanent remote noise monitoring stations (NMS) located in Newport Beach,
Santa Aha, Tustin and Irvine to measure noise levels, at the following locations:
MONITOR STATIONS
NMS-IS: Golf Course, 3100 Irvine Ave., Newport Beach
NMS-2S: 20152 S.W. Birch St., Santa Aha
NMS-3S: 2139 Anniversary Lane, Newport Beach
NMS-4S: 2338 Tustin Ave., Newport Beach
NMS-SS: 324 '/2 Vista Madera, Newport Beach
NMS-6S: 1912 Santiago, Newport Beach
NMS-7S: 1131 Back Bay Drive, Newport Beach
NMS-8N: 17372 Eastman Street, h'vine
NMS-9N: 1300 S. Grand Avenue, Santa Ana
NMS-10N: 17952 Beneta Way, Tustin
The map in Figure 1 shows the general location of each permanent remote monitor station.
Figure 2 shows the Airport's "Noise Impact Area" for thc previous year (April 1, 2000 - March
31,2001). The Figure 2 information was developed by Mestre-Greve Associates, Inc., in
consultation with John Wayne Airport. CNEL values measured for the period and current
digitized land use information were utilized to calculate the land area acreages, number of
residences and estimated number of people within the "Noise Impact Area".

COMMUNITY NOISE EQUIVALENT LEVELS
The monthly, quarterly and twelve month Community Noise Equivalent Level (CNEL) average values
for each monitor station are shown in Table 2, while daily CNEL values are shown in Tables 3 through
5. Insufficient data is indicated by "#N/A" entries in each table.
Average Single Event Noise Exl:x)sure Level (SENEL) values for Air Carrier and GA Jet aircraft are
shown in Tables 6 through 8.
For the twelve month period ending March 31, 2001, 104 dwelling units in Santa Aha Heights were in
-4-
the "Noise Impacted Area" (within the 65 dB CNEL contour); there has been no change in the number of
dwelling units in the "Noise Impacted Area" from the previous twelve month period ending December
31, 2000.
The State has approved several remedies of aircraft noise levels for noise sensitive property in the "Noise
Impact Area": homes can bc acoustically insulated, purchased by the County, or rczoned for "other
non~noise sensitive uses." As part of the County's Santa Ana Heights Land Use Compatibility Program,
approximately 77 general agriculture (A-1) properties with residential land uses on Orchard, Acacia and
Birch Streets were rczoned for Business Park Use in October, 1986. Each property was individually sold
and subsequently converted to compatible land use. Between 1986 and 1993, 124 residences have been
purchased or otherwise made compatible through thc County's Purchase Assurance Program, Acoustical
Insulation Program or Housing Relocation Program. In September 1993, the FAA approved a grant to
fund a voluntary Accelerated Acoustical Insulation Program (AAIP) in Santa Aha tteights. (The current
AAIP has been renamed "Santa Aha Heights Acoustical Insulation Program" with thc acronym
"SAH ALP".) During the first quarter of 2001, no additional residences were made compatible through
the County's SAIl AIP. A total of 267 residences in Santa Aha lteights have been purchased or
otherwise made compatible through the County's Purchase Assurance Program, tlousing Relocation
Program, Acoustical Insulation Program or SAH AlP.
TELEPHONE COMPLAINT CALLS (January I, 2001 - March 31v 2001)
The Airport's Access and Noise Office receives and investigates noise calls and complaints from local
citizens and all other sources. During the period January 1, 2001 through March 31,2001, the Office
received 561 complaints from citizens. This is a 79.2% increase from the 313 complaints received last
quarter. It is a 28.7% decrease from the 787 complaints received during the same quarter last year.
Figure 4 shows the distribution of the quarterly telephone calls and complaints from local communities.

Noise Abatement Committee Meeting
March 8, 2001
2:00 p.m.
Eddie Martin Building
AGENDA ITEMS AND ITEMS DISCUSSED:
1. Airport Statistics
Bonnie Streeter gave an update on the Airport Statistics citing information published in
the JWA Airport Statistics report for January 2001. She noted increases from January
2000 levels in the number of passengers, air cargo tonnage lifted, air taxi operations and
military operations. General aviation and air carrier operational levels were both below
last January's levels.
2. Capacity Allocations for the 2001-02 Plan Year
John Leyerle explained that on February 6, 2001, the Board of Supervisors approved the
allocation of commercial, commuter and cargo carrier capacity for operations in the 2001-
02 Plan Year which begins on April 1, 2001. Based on the approved capacity allocations,
we anticipate approximately 130 commercial air carrier departures on average per day
during the 2001-02 Plan Year. John further noted that the Board approved Class E
capacity allocations for the next three Plan Years (through March 31, 2004) in order to
stimulate additional passenger traffic. Capacity plans provided by the air carriers indicate
the potential for some additional flights and service to new markets over the next three
Plan Years.
3. New Entrant on April 1~ 2001 (Aloha Airlines)
The Board of Supervisors approved capacity allocations for Aloha Airlines, effective
April 1, 2001. Aloha has proposed service of two daily Class A departures to the
Hawaiian islands of Oahu and Maui, as well as one daily Class E departure to Las Vegas.
The airport must return to the Board of Supervisors to obtain approval for a lease
agreement with Aloha Airlines. (At that time, leases for Federal Express and United
Parcel Service will also be considered.) Aloha Airlines cannot initiate service at John
Wayne Airport until they receive a signed lease agreement with the County.

Noise Abatement Committee Meeting (continued)
4. Status of the Santa Ana Heights Acoustical Insulation Program (SAHAIP)
Carl Braatz provided an update on the status of the SAHAIP. A job walk for AlP Phase 8
was held recently. This phase will provide acoustical insulation for 24 single-family
dwellings in Santa Ana Heights. The insulation of a 182-unit apartment building located
at the corner of Mesa Drive and Irvine Avenue is 35% complete. After completion of the
apartment complex and Alp Phase 8, there will be approximately 100 remaining eligible
dwelling units in the Santa Ana Heights area. The SAHAIP will send an additional letter
to these properties in the near future, to determine if the owners are interested in
participating in the acoustical insulation program.
Carl also noted that the Daily Pilot newspaper would feature an article on the SAHAIP in
its March I 1, 2001, issue.
Question: Pete Drummond asked what effect an increase in flights at John Wayne
Airport would have on the SAHAIP eligibility area.
Answer: John Leyerle explained that the SAHAIP eligibility area is defined by the
projected 65 dB CNEL contour in the John Wayne Airport 1985 Master Plan. He noted
that the actual measured 65 dB CNEL contour has been consistently quieter than the
projected contour.
5. Any additional questions
Question: In reference to the departure procedures in use by the air carriers, Pete
Drummond asked if the air carriers were executing the left-hand turn from their initial
runway heading to a heading that would position them over the Back Bay for their transit
to the coastline.
Answer: John Leyerle responded that generally the air carriers are adhering to the
standard departure procedure (called the MUSEL 6 departure) out of John Wayne
Airport. This departure procedure specifies that approximately one mile from the airport
an aircraft initiate a left-hand turn from the 194 degree runway heading to a 175 degree
heading. There is, however, some variability in aircraft flight tracks. If a carrier tums a
few seconds early or late, their variation can be 1,0(}0 - 1,500 feet. Two to three miles
from the airport the departure corridor is 4,000 - 5,000 feet wide. John explained that the
airport has no control over aircraft flight paths. The Federal Aviation Administration has
jurisdiction in this area, and they have stated that this level of dispersion is typical and
fully acceptable for safe aircraft operation. John pointed out that 7%-8% of the aircraft
ground tracks are well over the communities to the west and east of the Back Bay and that

Noise Abatement Committee Meeting (continued)
complaints from these areas comprise a large percentage of the total complaint calls
received by the John Wayne Airport Access and Noise Office.
6. Tentative date for the next Noise Abatement Committee meetin~
The date for the next quarterly Noise Abatement Committee meeting will be announced
by letter approximately two weeks before the meeting.

INTRODUCTION
This is the 114th Quarterly Report submitted by the County of Orange in accordance with the
requirements of thc California Airport Noise Standards (California Administrative C0dc Title 21.
Chapter 2.5, SubChapter 6: Division of Aeronautics Noise Standards). Effective January i,
1986, the criteria for defining "Noise Impact Area" was changed from 70 dB to 65 dB
Community Noise Equivalent Level (CNEL). Under this criteria, John Wayne Airport currently
has a "Noise Impact Area."
NOISE IMPACT SUMMARY
Caltrans' Aeronautics Program has established guidelines in the California State Noise Standard
to control residential area noise levels produced by aircraft operations using thc State's airports.
Under those guidelines, residential noise sensitive areas exposed to an average Community Noise
Equivalent Level (CNEL) of more than 65 dB define thc "Noise Impact Area." John Wayne
Airport uses ten permanent remote noise monitoring stations (NMS) located in Newport Beach,
Santa Ana, Tustin and lrvine to measure noise levels, at the following locations:
MONITOR STATIONS
NMS- 1 S: Golf Course, 31 (X) Irvine Ave.. Newport Beach
NMS-2S: 20152 S.W. Birch St.. Santa Ana
NMS-3S: 2139 Anniversary Lane, Newport Beach
NMS--4S: 2338 Tustin Ave., Newport Beach
NMS~5S: 324 V2 Vista Madera, Newport Beach
NMS-6S: 1912 Santiago. Newport Beach
NMS-7S: 1131 Back Bay Drive, Newport Beach
NMS-SN: 17372 Eastman Street, lrvine
NMS-9N: 1300 S. Grand Avenue, Santa Ana
NMS-10N:I7952 Beneta Way, Tustin
The map in Figure I shows the general location of each permanent remote monitor station.
Figure 2 shows the Airport's "Noise Impact Area" for the previous year (July I, 2000 - June 30,
2001). The Figure 2 information was developed by Mestre-Greve Associates, Inc., in
consultation with John Wayne Airport. CNEL values measured for the period and current
digitized land usc information were utilized to calculate thc land area acreages, number of
residences and estimated number of people within the "Noise Impact Area".

COMMUNITY NOISE EQUIVALENT LEVEI.S
The monthly, quarterly and twelve month Community Noise Equivalent Level (CNEL) average values for each
monitor station are shown in Table 2, while daily CNEL values are shown in Tables 3 through 5. Insufficient data is
indicated by "#N/A" entries in each table.
Average Single Event Noise Exposure I,evel (SENEL) values for Air Carrier and GA Jet aircraft are shown in Tables
6 through 8.
For thc twelve month period ending June 30, 2001, 103 dwelling units in Santa Ana Heights were in the "Noise
impacted Area" (within thc 65 dB CNEL contour): this represents a decrease of one unit in the number of dwelling
units in the "Noise impacted Area" from the previous twelve month period ending March 31, 2001.
The State has approved several remedies of aircraft noise levels for noise sensitive property in the "Noise Impact
Area": homes can be acoustically insulated, purchased by thc County, or rezoncd for "other non-noise sensitive
uses." As part of the County's Santa Ana Heights Land Usc Compatibility Program, approximately 77 general
agriculture (A-I) properties with residential land uses on Orchard, Acacia and Birch Streets were rezoned for
Business Park Use in October. 1986. Each property was individually sold and subsequently converted to compatible
land use. Between 1986 and 1993, 124 residences have been purchased or otherwise made compatible through the
County's Purchase Assurance Program, Acoustical Insulation Program or Housing Relocation Program. in
September 1993, the FAA approved a grant to fund a voluntary Accelerated Acoustical Insulation Program (AAIP) in
Santa Aha Heights. (Thc current AAIP has been renamed "Santa Ana Heights Acoustical Insulation Program" with
the acronym "SAH ALP".) During the second quarter of 2001, no additional residences have been made compatible
through the County's SAH AlP. A total of 267 residences in Santa Ana Heights have been purchased or otherwise
made compatible through the County's Purchase Assurance Program, Housing Relocation Program. Acoustical
Insulation Program or SAH AlP.
TELEPHONE COMPLAINT CALLS (April I, 2001 - June 30~ 2001)
The Airport's Access and Noise Office receives and investigates noise calls and complaints from local citizens and all
other sources. During the period April l, 2001 through June 30, 2001, the Office received 569 complaints from
citizens. This is a !.4% increase from the 561 complaints received last quarter. It is a 21.0q4, decrease from thc 720
complaints received during the same quarter last year. Figure 4 shows thc distribution of the quarterly telephone calls
and complaints from local communities.

NOISE ABATEMENT COMMYlq'EE MEETING
Date: June 21,2001
Time: 2:¢X) p.m.
Place: Eddie Martin Building
AGENDA ITEMS AND ITEMS DISCUSSED:
1. Airport Statistics
John Escobedo gave an update on the Airl~)rt Statistics citing information published in the
JWA Airport Statistics report for May 2001. He noted decreases from May 2000 levels in the
number of passengers, air cargo tonnage lifted, total operations, air taxi operations and
military operations. General aviation and air carrier operational levels were both below last
May's levels.
2. New service destinations by Aloha and Southwest Airlines
Aloha Airlines began service on May !, 2(X)I to Oahu and Las Vegas and added another
flight on June I, 2001 to Maui. Southwest Airlines began new service on June 10, 2001 to
Las Vegas and Phoenix.
3. Status of the Santa Ana Heights Acoustical Insulation Program (SAHAIP)
Bonnie Streeter provided an update on the status of the SAHAIP. She noted that Ibr AlP
Phase VII, the 182-unit apartment building located at the comer of Mesa Drive and lrvine
Avenue is 95% complete. For AlP Phase Vlll, a contract as awarded on May 8, 2001 for the
insulation of 25 additional units. Carl Braatz is in the process of gathering names for the next
group.
4. Demonstration of TAMIS Communicator real-time noise levels
John Escobedo gave an explanation of the noise level measurement display.
Question: Pat Paddison asked do people look at SENEL or Lmax.
Answer: John Leyerle explained differences between CNEL and SENEL.
Question: Roger Sanders asked where do executive jets fall into JWA regulations.
Answer: John Leyerle explained GANO vs. Commercial regulations.
-17-
NOISE ABATEMENT COMMITTEE MEETING (continued)
Question: Roger Sanders stated he gets calls to the homeowners association about jets that
depart every morning at 6:30 am. It is very quiet then. st) this is very noticeable.
Answer: John Leyerle explained that there are 4(X),(XX) GA operations ever5, year. We
monitor all these operatk)ns and compare noise levels with noise limits. Explained the denial
penalty.
Question: Joseph Edwards asked why are there st) many more noise monitors It) the south
as compared to the north and also is it possible that other areas are getting overflown where
there are no monitors and therefore nol being recorded.
Answer: John Leyerle explained that in the early 1980's thc Board of Supervisors
wanted to expand JWA. Communities to the north and south were concerned. Law suits lead
to a Federal Court settlement agreement in 1985. Parties to the final settlement agreement
were the City of Newport Beach, AWG and SPON. While some representatives from Tustin
and Santa Ana where involved at some stage, the parties to the final agreement were from thc
Newport Beach area. Thus the number and location of the noise monitors was influenced by
the involvement, or non-involvement, of communities. Other reasons are that there is more
noise generated on departures due to takeoff' thrust versus arrivals. The noise impacted area
of the 65 dB CNEL contour is located in Santa Aha Heights which is south of the airport.
Communities to the north are removed from the 65 contour by many miles. The question of
why JWA doesn't site additional monitors comes up periodically. The airport has always
been supportive. If a community is willing to t'und the placement of a new monitor, at a cost
of $25,000 to $50,000, JWA would be happy to do that. However. due to the passage of
ANCA in 1990, any new restrictions on noise that were not specifically grandfathered, are
prohibited. So data from any new locations would have to be for informational purposes only.
To the best of our knowledge, the contours in the quarterly relx)rt and the annual contours
show that there are no communities other than the Santa Ana Heights area that are in the 65
dB CNEL impact area.
Question: Robert Shepherd asked isn't the CNEL the average noise and doesn't it
average in the quiet times.
Answer: John Leyerle defined CNEL as "24 hour weighted noise average". He also
explained that the CNEL has been the standard for federal, state and local authorities since
the 1970's. Mark Esslinger additionally explained that the quarterly report contours show the
measured 65 dB CNEL contour, but that the projected contour from the 1985 JWA Master
Plan is the contour adopted by the Board of Supervisors. This projected contour was
computer-calculated. John Leyerle added that the actual contour has been consistently smaller
than the projected contour.
-18-
NOISE ABATEMENT COMMITTEE MEETING (continued)
Ouestion: Roger Sanders asked is monitor I at Iht MtJSEL intersection.
Answer: Ramey Gonzalez explained that monitor 3 is closer to the MUSEI~
intersection and is where the commercial carriers execute their power cutbacks.
5. Any additional questions
Question: Pat Paddison stated in looking at the monthly CNEL tables in the most recent
quarterly report noticed that many monitors don't have a full months worth of data.
Answer: John Leyerle explained that monitors were up and running during that period,
but we experienced problems with the monitors from time to time. The noise staff works
diligently to resolve these problems as soon as possible.
Question: Robert Shepherd asked if the commercial carriers noise compliance period
was reduced from a calendar quarter, would that be in violation of ANCA.
Answer: John Leyerle explained that he could only speculate. The Board of
Supervisors has agreed to proceed with an EIR for the renegotiation of the settlement
agreement.
Question: Pat Paddison stated he keeps hearing that "nothing has changed" (with regards
to aircraft over his home) and maybe that's true as far as the FAA is concerned, but it has
changed dramatically over the last several months. Who brings the planes onto the ILS.
Answer: John Leyerle explained that the FAA has full control of airspace traffic, along
with the pilot in command, by Federal law. There is more control in a controlled airspace, in
Anaheim, as aircraft come from eastern airports to get on to the ILS, air traffic controllers at
Coast TRACON in San Diego are continuously in communication with the aircraft pilots
directing them through the airspace. The FAA's primary concerns are safety and efficiency.
They need to maintain separation of three miles. In the presence of wingtip vortices, they
need 5 miles of separation, e.g. the B757 aircraft which flies into JWA frequently. Two other
things have changed. The number of aircraft in the airspace has increased and the bunching of
aircraft operations in that airspace during peak-use times has also increased, thus increasing
the chances of routing over the Anaheim Hills area.
Question: Pat Paddison asked is there any way to change things.
Answer: John Leyerle's reply was the closer you are to any airport, the more difficult it
is to effect change.

Review of John Wayne Airport Noise Abatement Program
Quarterly Reports for the I~t and 2"d Quarters of 2001
Deal' Ms. Willkom,
As requested, we have reviewed the referenced quarterly reports for the noise
abatement program at John Wayne Airport. The following provides our
findings with regard to airport operations and their impact on the City of
Tustin:
1. Referring to Figure 1, the average annual CNEL at NMS 10N was 57.2 dB
for 2001 based upon data for the first two quarters. This is 0.1 dB lower
than the average annual CNEL of 57.3 dB for 2000. (NOTE: The noise
contours for John Wayne Airport are based on average annual CNEL
values measured at each remote monitoring station.)
2. The average annual CNEL o1'57.2 dB in 2001 implies the leveling off ol'a
modest upward trend in the aircrali noise exposure measured at NMS 10N.
This trend is illustrated in the following table:
1994
1995
1996
1997
1998
1999
2000
2001
56. i dB
56.4 dB
56.8 dB
55.9 dB
57.0 dB
56.8 dB
57.3 dB
57.2 dB
Refen'ing to Figure 2. thc number of noise complaints received from the
Tustin area does not appear to correlate with the average quarterly aircraft
CNEI, measured at NMS 10N, nor with the number of quarterly jet
operations at thc airport. As indicated in the figure, the average quarterly
CNEL increased steadily I'rom the fourth quarter of 2000 through the
second quarter of 2001, while the number of complaints from residents of
thc "l'ustin area remained relatively steady.

As indicated in Item 1, above, the annual average CNEL measured at NMS 10N was
57.2 dB through the second quarter of 2001. This is slightly less than the 58 dB that
was estimated for the station in the referenced aircraft noise impact study for the
Phase 2 Access Plan.
Aircraft Noise Contours
Figure 3 provides the estimated location of the John Wayne Airport noise contours for
2001. These are based on the 2000 contours developed by the John Wayne Airport Noise
Abatement Office, and data through the second quarter of 2001. Referring to Figure 3, it
is estimated that in 2001 the aircraft-generated CNEL ranged from about 59 dB to less
than 55 dB. This is well below the City, County, and State criteria of 65 dB for residential
areas.
Use of Quieter Aircraft at John Wayne Airport
The correlation between the increasing use of quieter aircraft at JWA and the change in
CNEL within the City of Tustin has been assessed. The Federal Aviation Administration
(FAA) classifies aircraft into three categories based on noise levels. In order of
decreasing noise levels, there arc Stage I, Stage II, and Stage III aircraft. John Wayne
Airport has only permitted Stage IIl aircraft since the early 1970's.
The airport has its own classification scheme for passenger aircraft. In order of
decreasing noise level, these are Class A, Class AA, and Class E aircraft. Table 1
provides the estimated number of each class of aircraft that used the airport between the
first quarter of 2000 and the second quarter of 2001. Also provided is the measured
average quarterly CNEL at NMS 10N. Table 2 provides the same information, but the
values have been normalized to 17,000 aircraft operations (takeoffs and landings) per
quarter. In this way, a correlation can be established between the quarterly CNEL and the
mix of aircraft types.
Referring to Table 2 and Figure 4, the percentage of quieter Class E aircraft using John
Wayne Airport has gradually increased since the beginning of 2000. This increase in
Class E aircraft was offset by a decrease in the use of the noisier Class A aircraft.
However, during this same time period, the average quarterly CNEL has been relatively
steady. Therefore, based on data from the first quarter of 2000 through the second quarter
of 2001, there does not appear to be any correlation between the aircraft mix and the
average quarterly CNEL at NMS 10N.
