Forecasts of aviation activity are an essential part of the System Plan (MASP) 2008. Planning for changes in aviation demand is a primary objective of the MASP 2008. The amount of activity generated by future users determines the demand for the airport facilities that make up the state system. The primary measure of general aviation demand is based general aviation. Based aircraft at each airport are used to forecast operations and facility utilization.

General aviation represent the majority of the facilities included in the MASP 2008. However, the unprecedented growth in commercial aviation has not been re- flected in general aviation activity. Many facets of general aviation in the U.S. have de- clined steadily throughout the airline industry. Contributing factors of this decline were deregulation of the airline industry, loss of tax incentives for aircraft ownership, high interest rates and lack of new technology. In addition, laws and rulings which have increased the civil liability awards for domestic aircraft suits virtually brought general aviation construction to a halt, and to some extent, moved the manufacturing indus- try overseas. These, along with increased aviation fuel prices, have served to further adversely affect an already depressed industry. These factors have reduced the growth in general aviation activities in Michigan and the U.S. aviation industry in general.

Many of these same factors have helped to lower interest rates, spur the develop- ment of new technology, and produce a turnaround throughout the industry. The laws and rulings covering civil liability awards have almost ceased. These rulings, along with lowered aviation fuel prices, have helped spur the aviation industry and new aircraft manufacturing and sales. Aircraft manufacturers are using new technol- ogy that involves composite materials and Global Positioning System (GPS).

The MASP 2008 serves as an important component of the NPIAS. As such, it includes airport locations that are considered to be important to state air transportation ob- jectives as well as those that are of sufficient national interest to be incorporated in the NPIAS. The MASP 2008 planning process also assists in identifying airports that meet national criteria, but might not be identified by the FAA alone. In addition, the airport development included in the MASP 2008 is limited to those items of develop- ment eligible not only for federal financial aid, but state aid as well. To be included in the NPIAS and become eligible for federal funding, an airport must first be included in the MASP 2008.

MASP 2008 Forecast Objectives

The purpose of state airport system planning is to determine the location, service FORECAST METHODOLOGY level, role criteria, and timing of airport development needed in the state to estab- lish a viable, balanced integrated system of airports. The MASP 2008 is designed to identify those airports that will perform an essential role in the economic and social development of Michigan.

Airport system planning is a continuous process which identifies the level of federal, state and local capital investment required to maintain and develop system airports. It provides guidance for the expenditure of funds under the FAA AIP and the MDOT Airport Development Program. The planning process also supports the development of state aviation policies.

111 APPENDIX These forecasts will also assist in the capital improvement identification needs of the MASP 2008. Airports have been identified as a part of the planning process in order to provide a guide for programming federal and state funds for airport development.

The individual airport master plan objectives are to identify issues, goals and needs of the specific airport and to provide a guide for how to best meet future aviation de- mand. The airport master plan focuses on developing an attainable, detailed, phased development program that will satisfy the airport needs in a safe, economical, ef- ficient and environmentally sound manner. The plan serves as a guide to decision makers, airport users and the public concerning realistic and achievable airport devel- opment in line with both the airport and community objectives. The airport master plan process provides a forum for discussing airport and local community objectives and establishing the linkages between community goals and those of the airport.

General aviation airports with roles of sea plane bases or heliports were not evalu- ated as part of this update of the MASP 2008. Scheduled airline service was not studied under the MASP 2008, but the operations and based aircraft at the air carrier sites were studied.

Forecast Usage in the MASP 2008 Forecasts of aviation activity are important to the evaluation of future airport needs and facility requirements. These are used in different calculations throughout the individual airport master plans and designs. The facility requirements section of the MASP 2008 will utilize these forecasts to determine airport deficiencies and the prior- ity of airport needs for Michigan’s 235 public use airports.

Definitions The following are key definitions used in the MASP 2008 Forecasts:

Total Operations: An operation is defined as a take-off or a landing. If an aircraft departs from an airport, flies to another destination, and flies back to the originating airport, the airport is considered to have two operations: one takeoff when the airplane left the airport, and one landing when the aircraft returned. Local Operation: A local operation is a take-off or a landing conducted by an aircraft which is usually based at the local airport. The smaller airports are more often used for local operations such as local training, recreation flights and crop dusting. Itinerant Operation: The definition of an itinerant operation is a take-off or landing conducted by an aircraft that is not based at the local airport and is generally based at least 25 miles from the specific airport. Total operations are important in that they measure the existing and poten- tial activity of the airport. Factors which contribute to these figures include: location of the aircraft traffic counters, weather, economic activities at the airport and the economy of the area and/or the state of Michigan. Other seasonal factors at the airport could be changes in flight training activities, price of aviation fuel, pricing of hangars, and the location of the airport in relation to the home or business of the aircraft owner. Fluctuations may oc- cur for a variety of reasons in any of the above factors. 112 The breakdown of local and itinerant operations are valued in the MASP 2008 because they differentiate between a business flight (an itinerant op- eration) and a training or a recreational flight (a local operation). Operations which are considered itinerant operations are important elements of the local economy. These aircraft are traveling to the local airport from different destinations by corporate flights carrying passengers and freight. The operations which are considered itinerant operations are very important factors in the Michigan Aviation System. These aircraft are traveling to local airports from various cities in the U.S., Canada and Mexico. The forecasts of activity for the MASP 2008 over the 25-year planning period, assuming the base year of 2005, are shown in Table 63. These forecasts of operations are shown in different categories which are depicted to evaluate airport facilities. Each of these different formats are shown because they represent a different element of data for the MASP 2008 forecasts and the necessary FAA design standards for the airport facilities. Based Aircraft: An aircraft is considered to be based at an airport if it uses that airport as a permanent parking area. The number of based aircraft is an important figure because it is used to determine airport facility requirements.

Changes in Technology One reason for optimism in the aviation industry is significant changes in technol- ogy have occurred in all elements of the aircraft fleet. These changes are presenting new opportunities for longer trip lengths (stage lengths), and for more fuel efficient, faster, and quieter aircraft engines.

Some of this new technology has been the use of composite materials and Micro- wave/GPS in aircraft manufacture. A microwave landing system is a new type of instrument landing system which, when fully installed, will allow landing procedures in conditions which are currently not possible. This system is not yet serviceable, and will be used as an approach system due to the advent of the GPS. The GPS uses satellites to determine exact locations, and with the addition of a ground net, can determine altitude. It is being considered as the precision instrument landing system of the future. It is less expensive to equip and maintain onboard the aircraft than on the ground facilities. The GPS would be installed in place of existing Instrument Landing System and microwave landing systems.

Growth in Regional and Classes of Airports Some general aviation airports, especially former U.S. Air Force Bases need upgrad- ing. At these locations there is business and cargo aircraft operating with heavier and larger aircraft than at standard transport locations. These larger aircraft have requirements for all weather facilities, paved surfaces, and lighting, precision landing systems, and fuel sales.

Runways in excess of 5,000 feet can accommodate scheduled air carrier passenger service and can act as cargo hubs. Runway lengths of 4,500 to 6,000 feet would be utilized by business and cargo users. Airport complexity increases with use by jets and cargo aircraft, which demand extra engineering and planning to accommodate. 113 MDOT FORECAST METHODOLOGY Initial investigation has shown that Michigan will continue to experience modest growth in the general aviation industry. The Bureau of Transportation Planning has developed a forecast system which is felt to accurately model the future growth in Michigan’s general aviation operations.

The Bureau of Transporation Planning models are based on linear regression meth- ods using historical data collected from TMS and AIMS.

Developing the MDOT Forecast Models In order to forecast the based aircraft and the total operations at each airport, the Bureau of Transportation Planning and Bureau of Aeronautics & Freight Services concluded that separate models be developed for airports based on class and re- spective region. Separate models for based aircraft and total operations were devel- oped using the categories previously mentioned.

Step one: Model Development and Calibration The first step in establishing the regression models was to graph the based air- craft and total operations in each category versus their respective historical year. Step two: Group Forecasts After the trend, line equations were developed and calibrated for each fore- casted category, values for the forecasted year were determined by inserting the forecast year into equation 1.

TF = M * (Ty) + B (Equation 1)

TF = Total Based Aircraft/Ops in Forecasted Year (Ty) M = Slope of Trend Line Ty = Forecast Year B = Y - Intercept

An example of Step two, using equation 1 is shown below. The example problem determined the forecasted based aircraft in 2030 for the model developed and illustrated in figure 2. Example: Determination of Total Based Aircraft Using Equation 1. T2010 = 1.7818 * (2030) - 2840 T2010 = 777 (Based Aircraft in Year 2030)

The output from the equation gives the “total” (based aircraft or operations) for the entire category in which the model forecasts. If, for example, the model were used for all C-II class airports within the Bay region, the equation would forecast a total of 777 based aircraft in the year 2030. The forecasted values, both based aircraft and total operations, for each year (2010, 2020, and 2030) were then used to determine a growth factor. Step three: Growth Factors The growth factors were determined based on the actual 2005 data. The individual

114 growth factors are obtained by dividing the respective growth at each air- port by the 2005 data, as shown in equation 2.

⎡ B f − B2005 ⎤ GF = ⎢ ⎥ (Equation 2) ⎣ B2005 ⎦ GF = Growth Factor Bf = Forecasted Value B2005 = 2005 Value This example illustrates the determination of a growth factor for the year 2030 at airports within a class and region that had a total of 720 based aircraft in 2005. From the previous step, it is determined there will be 777 based aircraft in the year 2030. Example: Calculation of Growth Factors

⎡777 − 720⎤ GF = 1+ ⎢ ⎥ ⎣ 720 ⎦

GF = 1.0792 Step four: Individual Airport Forecasts After the growth factors for each category of airport were developed, the growth factors were multiplied to each airport’s respective 2005 value to de- termine the forecast year projection for each individual airport. If the growth factor is below 1.0000, it is projected that the based aircraft or total opera- tions is expected to decline from the 2005 value. A growth factor which is higher than 1.000 would lead to the assumption that the airport is forecasted to grow in either based aircraft or total operations. PF = P2005 * GF (Equation 3)

PF = Forecasted Based Aircraft/Total Ops At an Airport P2005 = 2005 Historical Data (Based Aircraft or Operations) GF = Growth Factor (Determined in Previous Step)

The example below shows the projected aircraft in 2030 for an example air- port which had 75 based aircraft in 2005. The airport has a projected growth factor of 1.0792 (determined in previous step). Example: Individual Airport Forecast PF = 75 * 1.0792 PF = 81 (Forecasted Based Aircraft in 2030)

Step five: Local - Itinerant Split The previous steps have shown the procedure to calculate the based aircraft and total operations at an individual airport for a given forecast year. The following procedures discuss and illustrate the procedure for calculating the local and itinerant operations split at each airport. The growth in operations within the forecasted period is expected to occur in itinerant operations while local operations growth projections are expected to decrease. More growth is anticipated within business (itinerant) operations 115 than local. In order to take these presumptions into account, factors were de- veloped which allocated the total growth at an airport into the respective lo- cal/itinerant operational split. Smaller airports (A-I, B-I, and D-II) are expected to have 50 percent of the total growth in local operations while larger airports (C-II, C-III, C-VI, D-III, D-IV, and D-V) are expected to experience much higher itinerant operations growth. The table below shows the percentage of total growth which was allocated to local and itinerant operations.

Table 53 Local/Itinerant Split Factors Class Percent Local Percent Itinerant A-I 50% 50% B-I 50% 50% B-II 30% 70% C-II 20% 80% C-III 10% 90% C-VI 0% 100% D-II 50% 50% D-III 0% 100% D-IV 40% 60% D-V 0% 100% Source: MDOT Intermodal Policy Division The total growth forecasted at each airport was split between local and itinerant operations by the percentages shown above. The two values (local and itinerant growth) were then added to the respective 2005 local/itinerant split.

The equations below show the steps taken to find the local/itinerant operations split.

TG = PF – P2005 (Equation 4)

TG = Total Growth From 2005 PF = Forecasted (Based Aircraft or Total Ops) at an Airport P2005 = 2005 Historical Data (Based Aircraft or Operations)

SF = S2005 + (TG * S%) (Equation 5)

SF = Local/ Itinerant Forecast Value S2005 = 2005 Local/Itinerant Value S% = Percent of Total Growth Allocated to Local/Itinerant Operations

The following example is based on an airport with 5,000 total annual operations. In particular, the airport is a C-II airport and the forecasted total operations are 8,000 operations in a future year. Currently the airport is assumed to have 50 percent of the total operations being itinerant. 116 TG = 8,000 5,000 TG = 3,000

Local Operations: Future Year SL = 2,500 + (3,000 * .2) SL = 3,100

Itinerant Operations: Future Year SL = 2,500 + (3,000 * .8) SL = 4,900
