DEMAND/CAPACITY ANALYSIS & SITE SELECTION STUDY

CASE STUDY INSTRUCTIONS
DEMAND/CAPACITY ANALYSIS & SITE SELECTION STUDY
DEER VALLEY AIRPORT (DVT)

INSTRUCTIONS

Conduct a capacity and site selection study at Deer Valley Airport, Phoenix, Arizona. You should do the following:
1. Describe the historical aviation activity at the airport.
2. Develop a forecast of total annual demand for the airport using a trend analysis. You may use Microsoft Excel or other statistical software.
3. Determine hourly capacity, hourly delay and annual service volume for Deer Valley Airport using the short-term planning methodology and FAA Figures provided in
FAA Advisory Circular AC 150/5060-5, Airport Capacity and Delay. This methodology is also provided in Chapter 5 of the Aviation Planning textbook.
4. Select a suitable alternative site for Deer Valley Airport that could the same population as the existing airport.
5. Document your findings in a written paper.
6. Your documentation should be in the form of a written paper that includes the following sections:

1. HISTORICAL AVIATION ACTIVITY
This section should describe the types and levels of aviation activity at the airport over the past 20 years. It should include tables and figures as appropriate.
The tabulated data should include the number of based aircraft, the number of annual airport operations and the split between air carrier, air taxi, general aviation
and military operations as applicable. As a minimum, 20 years of historical data should be provided. Sources of data include: FAA ATADS at
http://aspm.faa.gov/opsnet/sys/Main.asp?force=atads. You may use the information presented in your paper on the airport’s existing conditions.

2. ANNUAL OPERATIONS, ADPM, PEAK HOUR FORECASTS
This section should include a forecast of total annual operations for Deer Valley Airport for the years 2015 through to 2025 using a trend analysis. Your trend
analysis should be based on the 20 years of data. In addition, develop forecast for the Average Day Peak Month and
Peak Hour operation in the years 2020 and 2025. In the Year 2020 the peak month will be March and is 9.5 percent of annual operations. In addition, peak hour
operations are 6 percent of operations during the average day of the peak month. In the Year 2025 the peak month will also be March and is 9.3 percent of annual
operations and peak hour operations are 5.5 percent of operations during the average day of the peak month.

3. HOURLY CAPACITY
This section should report on the determination of hourly capacity for the airport for the years 2020 and 2025. The Airport will close Runway 7R-25L, below, in the
Year 2025 for reconstruction. Explain why there are differences in hourly capacity between the five runway-use configurations. To complete this section you will need
to determine the separation between the runways and the available runway exit locations measured as distance from threshold in google earth. .

The runway-use configurations and the percent of the time they are used are shown in the tables below for the future Years 2020 and 2025. The arrows pointing towards
a runway end indicate arrivals on that threshold and those pointing away from a runway indicate the direction of departures from the runway.

The following additional information is given to complete your hourly capacity calculations:

Hourly Demand
The hourly demand for the Years 2020 and 2025 is presented below.

Hourly Demand – Year 2020
Aircraft Class Number of Aircraft Operations
VFR IFR
A 50 15
B 20 15

D 0 0

Hourly Demand – Year 2025
Aircraft Class Number of Aircraft Operations
VFR IFR
A 52 15
B 23 15
C 15 15
D 0 0

Percent Arrivals
The percentage of arrivals for the Year 2020 is 60 percent during VFR conditions and 40 percent during IFR conditions. It is anticipated that these percentages will
remain the same during the year 2025.

Touch and Go Operations
The table below presents the number of touch and go operations during the hour for the years under consideration.

Touch and Go Operations
Year Number of Touch & Go Operations
VFR IFR
2020 11 0
2025 13 0

4. HOURLY DELAY
This section should report on the determination of hourly delay for the airport for the years 2020 and 2025. Calculate hourly delay in VFR conditions for the Year
2020 and 2025 for runway use configurations No. 1 and No. 4. Explain why there are differences in the delay calculated for these two years. The following information
is required to complete your delay calculations.

Peak Fifteen Minute Demand
The table below presents the peak 15-minute demand during the busy hour for the years under consideration.

15-Minute Peak Demand
Year Peak 15 Minute Demand
VFR IFR
2020 25 15
2025 35 20

5. ANNUAL SERVICE VOLUME
This section should report on the determination of Annual Service Volume using the methodology for short-term planning. Explain how these ASVs compare to demand at
the airport. Plot a graph (with multiple lines) that charts ASV, 60 percent of ASV, and Annual Demand for the years 2020 and 2025. Analyze the graph and report your
findings. As part of your discussion answer the following question: What is the potential impact of the runway closure in the Year 2025?

6. SITE SELECTION STUDY
This section should identify a suitable alternative site Deer Valley Airport. The area of the alternative site should be able to accommodate all of the existing
facilities at the current airport and provide space for growth. You may use image from google maps or google earth in your site selection. At least three alternative
sites should be identified and evaluated. The following should be considered:
1. Convenience to population, including proximity to highways, railroads or other modes of surface transportation
2. Airspace
3. Surrounding obstructions
4. Availability for expansion
5. Availability of utilities
6. Meteorological conditions
7. Environmental and Noise impacts

7. RECOMMENDATIONS
This section should state your recommendations for Deer Valley Airport. These recommendations should be based on your demand/capacity analyses and site selection
study. Identify any further infrastructure development that is required both on and off-airport to support the future airport operations.

Planning/ Technical Report Writing

1. Write in concise clear sentences. Check your spelling and grammar and read your sentences out loud to ensure they make sense.

2. Cite your sources within your text. For example: “According to the Bureau of Economic Analysis (BEA), the population of Brevard County will grow at a rate of
1.5 percent over the next ten years.”

3. Do not use abbreviations within the main body of the document. For example, the symbol for feet or the abbreviation ft. should not be used. Write out the
word feet. Similarly, symbols such as % should be written out in full as percent. Symbols in Tables are acceptable if there insufficient space for the full text.

4. You may use acronyms in the main body of the report. However, they should be fully defined the first time they are used. Do not assume the reader knows what
they stand for. For instance: Medium-Intensity Approach Lighting System with Runway Alignment Indicator Lights (MALSR). After defining the acronym it may be then
used in subsequent text.

5. When using single digit numbers in the main body of the text write out the number and place the number itself in brackets. For example: “In 2010, the airport
had three (3) active FBOs. If your sentence starts with a number, write out the number regardless of the number of digits.

6. Read other planning study reports to see how information is written out or expressed.
