MEMO TO: Mayor and Council
SUBJECT: Hiring Process for Full-time Police Officer
DATE: April 29, 1987
THRU: Larry Thompson, City Administrator
As per directed by council on the April 6, 1987, meeting,
the following are suggestions and recommendations for the
hiring of a full-time police officer for the Farmington
Police Department.
The last two full-time police officers hired for the City of
Farmington have been hired through the ranks of our part-
time force. The part-time force has been a valuable tool to
the police department in that it allows us to view the part-
time employee for potential full-time employment. The
hiring of part-time employees has been conducted just •the
same as if we were hiring a full-time employee. The
advantage of this process has been that it has not taxed the
department in the hiring process where we have maybe one or
two part-time people that we are testing and interviewing
for employment versus hiring a full-time employee where we
may have as many as 300 applications to process at one time.
Since 1979, when the city approved the part-time status of
employees in the police department, we have had eleven of
these people go on to full-time jobs in other police
departments, two of which, with Farmington. I believe the
quality of the program speaks for itself as to the quality
of individuals in this program.
I request of the council to interview from within the part-
time ranks, possible candidates to be recommended •to the
council for approval to the full-time position. •
My second request would be to interview former employees of
the police department who have expressed a desire to come
back to Farmington to work. As of this writing, I have had
three former employees express a desire to return to Farm-
ington to work as a full-time employee with the police
department. THey are currently full-time police officers in
other jurisdictions, I believe that any one of the three
would do an excellent job for the City of Farmington. Since
each of these persons are currently practicing law enforce-
ment and former employees of the city, that very little
training would be involved in order for the individual to
assume full responsibilities of the job with very little
cost in training time.
Memo: Mayor and Council
April 29, 1987 Page 2
If I was unable to recommend a candidate to the council from
the above two processes, then I would request of the council
to test for the position and seek the necessary budget
adjustment to cover the cost of the hiring process. (See
attached sheet for break-down of cost to hire. )
Thank you for your consideration in this matter and if there
are any questions or concerns that you have, please feel
free to contact me.
Respectfully submitted,
Stan V. Whittingham

ALF AMBULANCE
1988 PROPOSED BUDGET
To the Honorable Mayor and City Council Members:
Attached to this letter is the proposed budget for ALF Ambulance for the
1988 fiscal year. Per the three City Ambulance Joint Powers Agreement, the
ALF Ambulance Board has reviewed, and are hereby recommending for approval
by the three City Councils the attached budget proposal.
It is my goal for fiscal year 1988 to see ALF Ambulance continue to deliver
high quality emergency medical services to the citizens in the ambulance
service area. We will strive to improve our service wherever and whenever
it is possible.
The following is a breakdown and short synopsis of the budget proposal:
The Ambulance Board has opted to increase the level of service to the three
communities by increasing coverage days of the second ambulance. The second
ambulance (Power Shift) is currently on (4) days a week with current days
and times of:
L: Saturday 12 noon - 10:00 p.m.
Monday 12 noon - 8:00 p.m.
Thursday 12 noon - 8:00 p.m.
Friday 12 noon - 8:00 p.m.
The proposed budget would expand power shift coverage to (7) days a week
with the same coverage of hours as listed above.
Since the start-up of the second unit in the fall of '86, it has proven
itself as quite an asset. Revenue generated from the second unit on
simultaneous calls (two units out at the same time) has nearly paid for the
salaries to staff that unit. Response times and coverage have also been
improved with the operation of the second unit.
Budget increases are:
- Salaries: Paramedics will progress from the 4 year pay level to the 5
year level which is a 2% increase. A maximum of 3% has been budgeted
for a cost of living increase/merit raise.
An additional $19,900.00* has been added to cover part-time salaries
and benefits for the additional (3) days of coverage by the second
ambulance.
* Because of the increase in coverage days with the second ambulance
there will be the ability to handle more simultaneous calls, which
means less dependence on mutual aid. Budget wise I am projecting
approximately $11,000.00 more in billable revenue.
Uniforms: $1,000.00 increase for uniform expense for (5) additional
part-time paramedics.
Fuel: $675.00 increase for gasoline to cover additional days.
Professional Services: $3,000.00 increase. This line item is for our
billing services (currently Sanford Hospital) .
Insurance: $3,500.00 increase. This is truly a hard item to budget
for. Our current insurance premium for 1987 is $11,675.00 which
includes $2,500.00 for umbrella coverage. Hopefully insurance rates
will have stabilized somewhat for next year and we should not exper-
ience a large increase.
Vehicle Repair: $2,000.00 increase. We put on about 20,000 miles per
year on each unit. As their mileage and age increase so will mainte-
nance costs and up-keep. The units also had an extended warranty which
covered them for major repairs, which is currently expired on one unit
and very close to expiration on the other.
This basically sums up the increases for the 1988 proposed budget. If any
Council Member should have any questions of require more information please
contact me.
Respectfully submitted,
Kevin J. Raun
Ambulance Director

MEMO TO: MAYOR AND COUNCIL
SUBJECT: AIRLAKE AIRPORT FORECAST OF AVIATION DEMAND
DATE: APRIL 29, 1987
I have reviewed the Airlake Airport Forecast of Aviation Demand prepared by Airlake
Airport Advisory Committee and would like to make the following observations.
If given a superficial review, the study appears to be sound, given the
statistical methods used to derive the various forecasts. Upon a more detailed
review, however, most forecasts are prefaced by "the data base was slightly
changed" (p.2-4) , "estimated by MAC" (p.2-4) , "amount of available data was
minimal for regression analysis" (p.2-7) , "Based on the assumption" (p.2-8)
"Based on MAC estimated annual operations" (p.2-12) , "lack of historical
data" (p.2-14) , "Due to lack of verifiable data operations were estimated"
(p.2-15) , "since there are no monthly operations records.. . and thus no
accurate way to determine" (p.2-16) , "Due to lack of historical data" (p.2-17)
etc. Yet the tables indicating existing 1986 data are not prefaced by the
term "estimated". When reading the tables, it appears that the 1986 data is
actual when, in fact, most of it is estimated. I would like to see the 1986
data that is estimated be clearly labeled. This would also be the case in
the text (e.g. p.2-15: This resulted in an "estimated" 54 operations per week
or an "estimated" 2,808 practice instrument operations per year.)
A second point is the reference to the impact of the Instrument Landing System
(ILS) recently installed at Airlake (p. 2-16) . The consultant states that the
impact will be mitigated by installation of similar devices at St. Paul
Downtown and Flying Cloud. Rather than present arguments why this might not
be the case (e.g. locations, traffic, etc.) the statement should be clarified
to state "may be balanced. . ."
Third, when certain statistics point to a potential boom at AirLake, the
consultant throws out the data by stating "it is felt that the growth
will not continue" (p.2-4) and ". . .such growth was felt to be unprecedented
and unlikely to continue" (p.2-4) . This is basically the same response the
City receives from Met Council staff when requesting additional urban service
area based on past growth. City staff was told in 1984 that 1983 was an anomaly.
Again, staff was told in early 1986 that 1983, 1984 and 1985 were blips and
that the remainder of the decade would even out. 1986, and now 1987, seem to
disprove these statements. The top graph on p.2-11 shows a steep increase
until 1986, then the consultant levels it off because "it is felt" the growth
should then stabilize.
Finally, the report only considers based aircraft, landings and practice
approaches. The Air National Guard and Air Force Reserve use the VOR located
just east of Airlake for practice. It would seem that these practice drills
would have an impact on airport safety.
•
In summary, while the report is based on statistical method, most of the
estimates are based on estimates, assumptions and gut feelings. Therefore,
the entire report should be clearly stated as such.

MEMORAN APR 2 22987
April 16, 1987
TO: Airlake Airport Advisory Committee
FROM: L. James Fortman, Director of Airport Development
Metropolitan Airports Commission
RE: Draft: Airlake Airport Forecast of Aviation Demand
The process of developing a long term comprehensive airport plan is a complex
one requiring input and data from many sources. This is certainly the case
for Airlake Airport and was the basis for the formation of the Airlake Airport
Advisory Committee. You were asked to participate in this committee because
of interests in the area around the airport, and most importantly, to discuss
and provide input from the people wham you represent.
Attached is the final draft copy of the Airlake Airport Forecast of Aviation
Demand as developed by our consultants, Hoyle, Tanner & Associates, Inc. We
request that you review this document with the group you represent and make
comments or suggestions on whether the document is understandable or if there
needs to be any further clarification. Please remember that this information
is a key part of the planning process and is used to establish the guidelines
for future airport improvements with the short term forecast considered most
accurate. The forecast will be updated in the future on a five (5) year
interval and adjusted to reflect conditions that might change the demand
levels.
We will also be obtaining comments from the Federal Aviation Administration,
the Minnesota Department of Transportation - Division of Aeronautics and the
Metropolitan Council. These comments will be reviewed with the Advisory
Committee as they are received.
We would appreciate having all comments by May 15, 1987.
Thank you for your continuing assistance in preparing the Airlake Airport Long
Term Comprehensive Airport Plan. We do look forward to the comments from your
representative group.

2 . 1 Introduction
Historically, aviation growth shows cyclical peaks and
valleys that forecasting tends to smooth out. In
addition, forecast numbers imply a range, not necessarily
a "hard" number . This chapter presents projections for
three forecast years : 1991 , 1996 , and 2006 . These
forecast years represent the short term, intermediate
term, and long term planning periods for the development
of the Airlake Airport Long Term Comprehensive Development
Plan. These planning periods are prescribed only as
guidelines with the short term forecast considered most
accurate . Planned improvements are more closely tied to
reaching forecast levels rather than to actual dates .
Thus , facility improvements will be keyed to a forecasted
level of activity, which might not necessarily fall within
the prescribed planning period.
In this element, the following data were determined to be
most critical in the development of the forecasts for
Airlake Airport:
• National , state, regional , and local trends of
various types and levels of aviation activity.
• Population and socio-economic data.
• Historical aviation data.
Limited historical data exists due to the airport' s recent
purchase by MAC and its function as a non-towered
facility. There has been one previous forecasting study
which included data for the Airlake Airport :
• Year 2003 Metropolitan Aviation System Plan
Technical Report by Charles River Associates
( 1985 ) , prepared for the Metropolitan Council
on aviation activities in the Minneapolis-
St . Paul Metropolitan area.
This study was developed for an entire metropolitan area,
not for any specific airport. The data was generated for
reasons other than that of a long-term comprehensive
airport development plan. Consequently, this source was
reviewed only for general knowledge and was considered not
entirely appropriate to the comprehensive planning
activities being performed for Airlake Airport .
2-1
The key to this forecasting technique was to identify
significant trends and data of sufficient accuracy and
then correlate this information with the expected aviation
activity and demand. Therefore , the significant data
included population trends , county and state aircraft
ownership, and economic development activities of the
area. Generally, the Airlake Airport area has shown a
significant population increase in relation to the
metropolitan area and is forecasted by the Metropolitan
Council to remain one of the fastest growing areas in the
future .
However , national aviation trends indicate that the long
term growth and activity levels of the general aviation
aircraft fleet may be declining . This may be caused in
large part by the rapidly rising aircraft prices ,
declining productivity, high operating costs due to tax
legislated changes and significantly higher product
liability insurance costs . The aircraft manufacturers are
having to pay substantially higher liability insurance
costs not only for their new aircraft but also for older
aircraft , sometimes dating back 25-30 years .
Consequently, aircraft prices have increased, resulting in
current aircraft owners putting their money into updating
their older aircraft with state-of-the-art avionics
( radios , navigational aids , etc . ) rather than purchasing
newer aircraft .
Nevertheless , the activity and numbers of aircraft at
Airlake Airport have increased in recent years .
Additionally, significant interest has been shown in the
development and demand for aircraft storage hangars , thus
influencing future activity levels and airport facility
requirements .
All of these factors will relate to the forecast data
presented in this chapter. These forecasts represent the
potential aviation activity with all of the elements that
tend to create aviation demand, without regard to any
constraints such as airspace , airport access , limited
airport expansion capability, or the airport functional
classification which could limit growth. However, all
potential constraints will be fully considered during the
alternatives evaluation effort and forecasts will be
adjusted as necessary to reflect constraints on either the
magnitude or types of projected aviation activities .
Due to the previously mentioned lack of historical data,
the consultant sought secondary sources of data and
employed various methods of forecasting . These factors
helped to establish reasonable and workable data to serve
as the basis for the planning of the airport ' s facility
requirement . The following four forecasting methodologies
9-9
•
were developed to establish the planning data base for
Airlake Airport and will be described in terms of their
development and application to the forecast of aviation
demand.
• Comparative Trend Analysis - a comparison of
known trends in aviation activity at all MAC
airports except Minneapolis-St. Paul International
(MSP) .
• Growth Rates Based on Population - developed to
generally identify a correlation between the
population trends of the Airlake Airport area
and the recent aviation activity of the airport.
• Regression Analysis Based on Population - a
statistical tool used to measure a relationship
between known variables . In this case, the
independent variable was the area' s
population, the dependent variable was the
airport ' s aviation activity.
• Market Share Analysis - developed to determine the
share of the aviation market that Airlake
Airport holds within the state (Minnesota) .
2 . 2 Forecast Methodology
2 . 2 . 1 Comparative Trend Analysis
Based Aircraft
From MAC records , the number of based aircraft at MAC
owned and operated airports , except MSP, was examined for
the period 1970-1986 . These airports were Airlake , Anoka
County, Crystal , Flying Cloud, Lake Elmo , and St . Paul
Downtown. Each airport was first analyzed individually
for year-to-year changes in based aircraft in order to
obtain an overall trend at airports in the metropolitan
area. Attention was then focused on more recent data,
namely that of 1983-1986 , years for which comparable
Airlake data was available.
A comparative trend analysis of the six airports over the
three year period showed an annual increase in number of
based aircraft only at Airlake and Anoka County airports :
approximately 36% per annum at Airlake, 4% at Anoka.
Crystal , Flying Cloud, St. Paul Downtown, and Lake Elmo
experienced either a decrease or no change. All but Lake
Elmo have physical constraints with little additional
aircraft storage space available at this time. While the
development of the Airlake forecast is undertaken
2-3
initially without consideration of potential constraints
on its development, it is felt that the growth in based
aircraft of approximately 150% in the past three years has
been unprecedented and will not continue at the current
rate . No other airport under consideration has recently
experienced a similar growth .
However, Anoka County airport experielced a generally
steady, overall trend in growth of bared aircraft which is
indicative of the direction in which Airlake is probably
proceeding . Except for a decline of approximately 6% in
1982 and insignificant changes in 1983 and 1986 , Anoka' s
based aircraft have been steadily inc ^easing since 1974 .
Recent general demographic trends in the Airlake and Anoka
communities indicate similar growth patterns . With these
factors in mind, Anoka' s based aircraft annual growth rate
of 4 . 2% was deemed reasonable and appropriate for
application to the most recent Airlake data ( 153 based
aircraft in 1986 ) in order to develop a forecast of based
aircraft .
Annual Operations
The comparative trend analysis method logy utilized in
forecasting based aircraft is basically the same for
projecting annual operations . However , the data base was
slightly changed. Because available operations data at
the non-towered airports is estimated by MAC, only the
towered airports of Crystal , Flying Cloud, and St . Paul
Downtown were considered. From MAC records , annual
operations data at these three airports was examined over
the period 1970-1986 . Individual yearly changes in annual
operations were calculated, and an in-depth analysis of
the period 1983-1986 was developed. Annual operations at
these three airports between 1983 and 1986 increased
between approximately 15% and 30%, with annual growth
rates ranging from 4% to 8 . 5%. Airlake ' s estimated
increase over a similar period was 100%, with a growth
rate of 26% per annum. Again, such growth was felt to be
unprecedented and unlikely to continue at that rate .
However, based on the comparative analysis of the three
towered area airports , a projected annual rate of 5 . 5%,
the mean rate of those airports , appeared reasonable.
Therefore , the 5 . 5% was applied to the Airlake 1986
estimated 40 , 000 annual operations to obtain a forecast of
annual operations .
2 . 2 . 2 Growth Rates Based on Population
Total population and population growth rates are two of
the most significant demographic elements impacting an air
transportation market and thus the forecasting of aviation
2-4
activity. Historically, a general relationship has been
established between population and aviation demand.
Therefore , consideration of local population trends within
the Airlake Airport geographic area is relevant to this
forecasting effort . Two diffe-ent approaches to
developing a forecast relating aviation activity and
population were employed: growth trend analysis and
regression analysis .
A time-distance related market area for Airlake users was
defined for use in both methodologies . Specifically, the
area encompassed all communities , or parts thereof, within
a 15 mile radius of the airport and an assumed driving
time of no more than 30 minutes under normal conditions .
Dakota and Scott Counties had the largest representation
of cities , towns and townships . Hennepin County' s share
was small ; Carver, Ramsey, and Washington were beyond the
15 mile radius .
Examination of population trends began with a compilation
of actual and forecast U.S .Deps.rtment of Commerce (Census )
and Metropolitan Council population counts within the
defined Airlake service area. The results reflected
substantial population increases between 1980 and 2000 :
Percent Increase

Ramsey County 2 . 8 3 . 7

In contrast , the U.S . Department of Commerce' s recent
population forecast indicates slower growth in both the
state of Minnesota and the United States as compared to
the Airlake service area.

Minnesota 6 . 6 16 . 5
United States 6 . 5 14 . 3
Source : U. S . Department of Commerce.
Based on these national , state , and regional forecasts , it
appears that the Airlake service area will continue to
grow rapidly, especially in the early part of the study
period.
As mentioned in the previous section, the recent increase
in the number of based aircraft at Airlake is
unprecedented. The largest percent change in based
aircraft at other MAC airports (excluding MSP) was at St .
Paul Downtown with 9% during the period between 1984 and
1986 . In determining a based aircraft growth rate at
Airlake related to population trends , a comparison of
actual growth increases was made .
1983-84 1984-85 1985-86
Airlake service
area population 2 . 5% 4 . 8% 5 . 0%
Based aircraft 3 . 3 47 . 6 64 . 5
Based on this trend, it is expected that based aircraft
will continue to grow at a faster annual rate than that
of the population over the forecast period. Annual growth
rates of 5% and 2% per year per 10 , 000 persons , or twice
the population annual growth rate ( 2 . 4% each year from
1986 to 1991 , under 1% thereafter) are considered
reasonable . In other words , the increase in the number of
based aircraft per 10 , 000 persons will grow faster, but in
approximate relationship to the growth in the Airlake
service area population: 5% from 1986 to 1991 , 2%
thereafter .
Annual operations were assumed to grow at a slightly
higher rate based on recent facility improvements , the
installation of an instrument landing system ( ILS )
approach and Airlake' s airport function as a secondary
reliever within the metropolitan airports system. These
rates were estimated at 8 . 8% up to 1991 , and 2 . 7%
thereafter to 2006 .

2 . 2 . 3 Regression Analysis Based on Population
Regression analys:.s is a forecasting technique for
estimating the mathematical relationship between one
dependent variables and any number of independent
variables . In fo -ecasting Airlake aviation activity, the
independent variable was population, the dependent
variable was number of based aircraft . In order to
develop a forecast , based aircraft at Airlake for the
period 1983-1986 were regressed in a simple linear formula
against populationdata for the Airlake service area.
While the amount of available aviation data was minimal
for regression analysis , the R-squared value , which
represents the degree to which an independent variable
explains the variz.tion in the dependent variable (based
aircraft) was . 9343 , indicating that a relationship did in
fact exist . In other words , as the Airlake service area
population increased, so did the number of based aircraft
at Airlake Airport .
A second analysis was performed using annual operations as
the dependent variable . The R-squared value was . 9634 .
Using projected service area population data, a forecast
of based aircraft and annual operations based on these
mathematical relationships were developed.
2 . 2 . 4 Market Share Analysis
A market share analysis was performed in order to develop
a forecast based on Airlake Airport ' s participation in
aviation activity within the state of Minnesota.
Participation in a larger context was not meaningful at
this time because of the limited amount of available
Airlake data and the magnitude of its numbers .
Based Aircraft
The total number of registered aircraft in the state of
Minnesota was obtained from FAA records for the years
1980-1985 . Estimates for 1986 , 1991 , 1996 and 2006 were
developed by applying a 1 . 0% annual growth factor to the
1985 data. This 1 . 0% factor was based on a FAA annual
growth rate forecast showing :
Total Active Aircraft 1 . 4%
Active Single Engine Aircraft 0 . 9%
Source : FAA Aviation Forecast, FY 1986-1997 .
2-7
Given the decline in general aviation shipments over the
last several years , a 1 . 0% growth factor appears generous .
The FAA reports declines in general aviation shipments of :
1979 4 . 3%
1981 21 . 0%
1983 37 . 0%
1984 10 . 0%
Source : FAA Aviation Forecast , FY 1986-1997 .
In order to develop a forecast , aircraft registration
records for each of the seven counties in the metro area
were examined and each county' s share (%) of the Minnesota
total was calculated for the years 1980-1985 . This showed
a remarkably stable market share for each county over this
time period .

However, when Airlake' s market share was determined, the
rapid growth experienced in based aircraft was reflected
in an increase in market share : 1 . 0% in 1983 , estimated at
2 . 6% in 1986 . Based on the assumption that Airlake ' s
growth in based aircraft will continue , its market share
should continue to increase , approximately doubling its
percent of market share between 1985 and 1991 , and
leveling off to a relatively stable share thereafter.
2-8
Annual Operations
Forecasts of annual operations at Minnesota non-towered
reliever and general aviation airports were developed from
FAA actual and projected Minnesota state data. The FAA' s
anticipated annual growth rates were extended over the
forecast years . The market share of operations at each
MAC airport ( excluding MSP) was calculated and analyzed
for trends . As in the case of based aircraft , the market
share of operations appears to remain stable over a period
of time .

However, Airlake' s share is growing as its aviation
activity increases . Its operations market share was 1 . 5%
in 1984 , and estimated at 2 . 3% in 1986 . Based on this
trend, it is reasonable to anticipate that Airlake ' s share
in the Minnesota market will continue to gain at
approximately 0 . 1% per year for the next five years , and
subsequently 0 . 5% until 1996 , when the share will
stabilize .
2-9
2 . 3 Preferred Forecast
Each of the four forecasting methodologies derived varying
aviation activity figures , none of which stand out as
being unreasonable or unreliable , and resulted in a range
of forecasts for Airlake Airport shown in Figure 2-1 . In
order to establish a workable set of forecast data for use
in the planning of airport facility requirements , it was
determined that the most reasonable activity data would be
selected from the forecast range for each forecast year
( 1991 , 1996 , 2006 ) . The data selected for planning
purposes were, in most cases , the high numbers from this
forecast range . The high numbers provide the most
effective means of planning the facility requirements
based on the maximum levels of aviation activity which are
expected to occur. This forecast data is usually updated
every five years to take into account any aviation or
economic trends that have had an impact on the airport .
Airport improvements are therefore based on the more
reliable , or short term five year data, rather than the
long term, 20 year data. The following sections identify
the preferred forecast of aviation activity for Airlake
Airport .
2 . 4 Based Aircraft Forecasts
The projection of based aircraft is used as a foundation
to determine many elements of future airport facility
requirements including hangars , tie-down areas and
aircraft parking aprons . As mentioned in the Introduction
of this chapter, the most reasonable numbers , as derived
from the forecast methodologies , are the basis for
planning . With these factors in mind, Table 2-1
represents the based aircraft for the forecast years at
Airlake Airport.

2 . 4 . 1 Based Aircraft Mix
Based aircraft must be identified and forecast by type to
primarily determine hangar requirements , noise contours
and other planning parameters . In 1985 the known based
fleet included 83 single engine aircraft , 6 multi engine
aircraft and 4 helicopters . It is assumed that by 1991
Airlake will base at least one business jet and turboprop
aircraft . The largest share of the forecasted fleet will
remain single engine aircraft but at a decreasing
percentage over the study period. Multi engine aircraft
are forecast to increase at an increasing rate ,
helicopters are forecast to increase slightly, and turbine
powered aircraft are forecast to increase generally
according to FAA forecasts . Table 2-2 reflects the
forecast fleet mix as applied to the based aircraft
forecasts .

2 . 5 Operations Forecasts
Introduction
Aircraft operations forecasts are used as a basis to
analyze runway and other airport facility capacities . As
with the previous section, annual operations will be
derived from the same forecasting methodologies used to
determine based aircraft . It should be noted that the
operations forecasts are based on the most current data as
collected by MAC, and represents MAC-estimated annual
operations due to the lack of verifiable data from a
control tower.

Therefore , using the same criteria and factors for
forecasting based aircraft , Table 2-3 shows the forecast
of annual operations at Airlake to be used for planning
purposes .

2 . 5 . 1 Operations Per Based Aircraft
Although not a forecast technique, the calculation of
operations per based aircraft is used as a check of the
validity of future reasonable growth activity at the
airport .
In order to put the Airlake Airport operations per based
aircraft in perspective, Table 2-4 compares these figures
for all MAC airports ( except MSP) over a ten year period.
This data is calculated from historical MAC records . It
shows a fairly high figure in 1976 for all the airports
that tends to decline over time . Table 2-4 further
identifies the future operations per based aircraft at
Airlake Airport based on forecast data for the forecast
time period.

2 . 5 . 2 Local/Itinerant Forecasts
On a national level , general aviation has benefited from
many technological improvements to aircraft, primarily
avionics and airframe composition material . While
increased costs of these improvements have adversely
affected the small private owner, this trend means
increased purchases of larger aircraft with more
sophisticated avionics for corporate and business travel .
This development impacts total operations because
itinerant flights will tend to grow faster than local
operations . Although the majority of operations at
Airlake Airport will remain local operations , the increase
in itinerant operations will correspond to the previously
mentioned national trend.
As stated earlier, the lack of historical data made it
difficult to identify any specific local/itinerant
operations trends at Airlake . Therefore , the consultant
analyzed known data for the MAC towered airports except
MSP (Crystal , Flying Cloud, St . Paul Downtown) . This data
came from two documents : the FAA FY 1985 Air Traffic
Activity and the FAA Terminal Area Forecasts , 1985-1995 .
From both documents the consultant generally found an
operations split at Crystal and Flying Cloud of 60% local
and 40% itinerant . The St . Paul Downtown split was
generally the opposite, or 40% local and 60% itinerant .
Due to the St. Paul Downtown airport ' s function as a
corporate/business aircraft facility, it was determined
that the operations data would be inappropriate for
purposes of this comparison and was therefore not
considered.
As a result of this comparison , a further determination
was made by the consultant that Airlake Airport operations
would eventually attain a similar 60% local and 40%
itinerant split by the year 2006 . Together with Airlake' s
existing estimated local/itinerant split of 85% local and
15% intinerant, the interim forecast years of 1991 and
1996 were calculated according to the corresponding
decline in local operations from 85% in 1986 to 60% in
2006 , and the corresponding increase in itinerant
operations from 15% in 1986 to 40% in 2006 . Table 2-5
represents these assumptions and calculations .

2 . 5 . 3 Annual Instrument Operations
Due to the lack of verifiable data from a control tower ,
annual instrument operations were estimated by the Fixed
Base Operator (FBO) . Practice instrument approaches were
estimated at six per day during the week and twelve per
day on the weekend. This resulted in 54 operations per
week or 2 , 808 practice instrument operations per year.
Actual instrument operations , or those which file an
instrument flight plan and land at the airport in
instrument conditions , were estimated at 48 operations per
day. The number of days in which instrument conditions
are present ( i . e. , less than 1 , 000 ft. ceilings and 3
miles visibility) is 24 days, as taken from known Wind
Rose (wind speed/direction computation) data. Therefore ,
there are 1 , 152 actual instrument operations per year.
When combined, there are 3 , 960 total instrument operations
(practice and actual ) per year . With 40 , 000 annual
operations in 1986 , there were 0 . 099 annual instrument
operations per annual operations .
A similar comparison to the MAC towered airports (Crystal ,
Flying Cloud, St. Paul Downtown) was made to determine any
trends in instrument operations and to reflect the
expected increase in sophisticated corporate/business
aircraft. As stated earlier , this national trend could
affect the number of operations since the more
sophisticated aircraft would tend to operate an instrument
approach at Airlake Airport, thus impacting total
instrument operations . This comparison of data was made
from the FAA Terminal Area Forecasts , 1985-1995 . It
showed a relatively stable rate of instrument approaches
over the time period 1983-1995 at all three of the towered
airports .
2-15
Another important factor which could influence the number
of instrument operations at Airlake Airport, and most
probably the practice instrument operations , will be the
installation of an Instrument Landing System ( ILS )
approach at St . Paul Downtown and Flying Cloud in the near
future . Although the number of sophisticated aircraft
could tend to increase instrument operations at Airlake
Airport , the consultant determined that this increase will
be balanced out by the installation of ILS approaches at
St . Paul Downtown and Flying Cloud, thereby lessening the
practice ILS approaches at Airlake Airport . Consequently,
and for planning purposes , the factor of 0 . 099 annual
instrument operations per annual operations will remain
constant throughout the forecast period. Table 2-6
reflects the annual instrument operations based on these
assumptions .

2 . 5 . 4 Peak Hour Operations
Peak hour operations forecasts are calculated from the
number of operations during an average day within the
month having the most operations , or the peak month. Peak
hour calculations are used to primarily determine runway
capacity, with additional use in analyzing other airfield
components and terminal capacities .
Since there are no monthly operations records at Airlake
Airport , and thus no accurate way to determine the
relationship between peak month operations and annual
operations , a percentage relationship was calculated from
the three towered airports in the area: Crystal , Flying
Cloud and St . Paul Downtown. Table 2-7 shows the
percentage of operations from the peak month to the total
annual operations for 1986 from the three airports .

St . Paul Downtown August 13 , 879 124 , 786 11 . 1

Table 2-7 shows an average of 11 . 1% of peak month
operations to annual operations at these airports. This
percentage was then used to determine the peak month
operations at Airlake Airport . Average day operations
were computed as 1/30 of the peak month . The consultant
then determined that based on its previous planning
studies of airports with similar characteristics , such as
a single runway, non-towered, active general aviation
facility, the peak hour operations could be determined as
15% of average day operations . Table 2-8 reflects these
peak hour calculations , identifying the maximum number of
aircraft operations which can be accommodated on the
airport ' s runway in an hour.

2 . 5 . 5 Night Operations
Night operations are defined as those which take place
between 10 P.M. and 7 A.M. Due to the lack of historic
data, night operations were based on an environmental
assessment study of Airlake Airport previously developed
by the consultant , and it was estimated that two percent
of the annual operations will occur at night . For
2-17
planning purposes , this figure was determined reasonable
and will be assumed constant throughout the study period.
Projected night operations are shown on Table 2-9 .
