9 Availability of Data for Modeling Veer-Off Risk The ultimate objective of this project was to characterize the risk of aircraft veer-off within segments or subareas of the RSA, and areas outside of, but contiguous to the RSA. To achieve these goals, it was necessary to develop risk models based on information collected from accident and incident reports.

10 The data collected onsite by the NTSB or received from other organizations, such as the FAA, is entered into the NTSB database. Although some incidents are reported in this database, most of the records available involve accidents and are used to support the NTSB's determination of probable causes and contributing factors.

11 conclusions derived from this study have allowed the identification of potential improvements in data collection that may, in the future, enhance the accuracy of veer-off risk models developed in this research. Most of the improvements that may be achieved are associated with including information to characterize the veer-off path during the runway excursion.

12 layout are available, it may be possible to make the field measurement from a known point and then add or subtract the distance to that point found on the engineering drawing. For example, "aircraft left the runway pavement, 150 feet beyond the north edge of the Taxiway Sierra intersection with the runway." The 150 feet measured in the field would be added to the distance from the beginning of the runway to the north edge of Taxiway Sierra that is measured on the engineering drawing.

13 traveling to the airport that other parties would incur would be minimized if an airport employee takes the measurements and collects the information described in this report. A simple self-administered, computer-based training program to explain the data that needs to be collected for the various types of veer-offs and how it will be used may be the tool to implement data collection.
