16 This chapter provides guidance on identifying the appropriate forecasting tools for analyzing planning and environmental problems, depending on the specific issue and the level of detail required or possible. It also describes available default factors, the capability of generating multiple scenarios, and the identification of key variables.

18 preparing peak period and Operational profiles -- Guidebook such as SIMMOD and TAAM are used to evaluate airfield needs and proposed solutions. Following are some general considerations for determining the appropriate level of detail for airfield planning: • New runways or runway extensions usually require FAA funding and a high level of environmental review, which then typically warrants the use of simulation modeling.

how to Use Guidebook and toolbox 19 3.1.2 Terminal Planning For the purpose of this Guidebook, the terminal area is defined as the terminal building including all concourses and gates. Exhibit 3.2 summarizes the types of terminal facilities, the tools typically used to analyze and plan for these facilities depending on the level of detail desired, and the types of forecasts needed to employ these tools.

20 preparing peak period and Operational profiles -- Guidebook There are four main categories, including gate analysis, departing passenger facilities, arriving passenger facilities, and other terminal facilities, in the exhibit. Many of the tools presented in the exhibit can be directly accessed in ACRP Report 25.

how to Use Guidebook and toolbox 21 lead time and probability distribution, the timing and intensity of the peak period flow at a given departure facility may not exactly match the enplaning peak. In addition, the following factors should be considered when determining the level of forecast detail for terminal planning: • At large airports, with a wide variety of airline services and passenger characteristics, inferring the appropriate passenger distributions for each departing passenger facility becomes increasingly complex, and a terminal simulation model requiring a design day schedule may be appropriate.

22 preparing peak period and Operational profiles -- Guidebook as airline offices are not directly affected by peak passenger activity. With the exception of the demand for restrooms, which is determined by a combination of peak arriving and departing passengers, the demand for most of these activities is determined by annual passenger levels or the configuration of other facilities such as gates.

how to Use Guidebook and toolbox 23 Curb and roadway requirements are highly sensitive to the configuration of the airport: the segregation of different types of demand (e.g., passenger versus employee) , and the segregation by vehicle type (e.g., private auto versus courtesy van)

24 preparing peak period and Operational profiles -- Guidebook Noise impacts from aircraft are usually estimated using the INM which has specific input requirements, namely AAD aircraft operations broken out by day/night split and aircraft type. The NIRS model is sometimes used instead; however, it requires a design day schedule as an input.

how to Use Guidebook and toolbox 25 The upcoming AEDT model will replace the EDMS model and the INM model; however, the input requirements will generally be the same. 3.2 Default Factors The seasonal, weekly, and hourly distribution of activity for airports varies depending on their size, their location, and the types of communities they serve.

how to Use Guidebook and toolbox 27 3.3.2 Use of Scenarios One method of addressing uncertainty is to use forecast scenarios. Forecast scenarios, in the form of high and low range forecasts, or more detailed contingencies based on variation of specific variables such as economic growth, are often used to portray the potential variance in annual forecasts.
