Software User Manual 49 Exhibit II-14. CurrentService worksheet. CurrentService Worksheet This worksheet shows the average weekly departures and average seat size for 2009 for each domestic market served nonstop at the airport. Exhibit II-14 is an example for ACY. This worksheet is consistent with the embedded TAF forecast, which is the default used in the model. The Baseline TAF forecast for ACY is found at the top of the Baseline&Scenarios work- sheet, and shown in Exhibit II-15. Updating the Baseline Forecast in the CurrentService Worksheet In the CurrentService worksheet, an important feature allows users to update air service information by adding service to new cities and/or changing the number of weekly departures and average seat size in existing markets (in the right two columns). Caution: It is very important to note that whatever changes are made in the CurrentService worksheet will become the Baseline Domestic Forecast in the Baseline&Scenarios worksheet. In effect the user is creating an updated Baseline using more current information. Exhibit II-15. Baseline forecast from the Baseline&Scenarios worksheet.

The revised CurrentService worksheet is shown in Exhibit II-16. Notice that changes in the CurrentService worksheet are in red. As noted previously, these changes in air service are automatically translated into a new Baseline Scenario in the Baseline& Scenarios worksheet. Once the Update Tables button is pressed in the CurrentService worksheet, the software automatically moves to the Baseline&Scenarios worksheet shown in Exhibit II-17. Notice that the Default Baseline Forecast is now higher than it was before the new service to Detroit was added. Caution: When updating the CurrentService worksheet, it is important to reflect all of the changes in air service, which will then be reflected in the New Baseline Forecast. Exhibit II-17.
