The FAA maintains a RIM program database updated on an annual basis, including only towered airports. During each annual update, all runway incursions and surface incidents (pilot deviation (PD) and vehicle/pedestrian deviation (V/PD)) from the previous calendar year (CY), including wrong surface landings and takeoffs, are georeferenced in the geographic information system database. An annual review of the layout of each airport determines if locations with previously identified nonstandard geometry characteristics have changed and/or been mitigated. New locations with nonstandard geometry characteristics are also identified. If a location has three or more runway incursions in a single CY or an average of one runway incursion per year since the program began, it is considered for inclusion in the RIM inventory.

This report captures the RIM program summary through FY19, annual updates, and current inventory. Since initiation of the RIM program in FY15, a total of 6445 runway incursions (PD and V/PD) and 239 nonstandard geometry locations were added to the database, bringing the total to 11544 runway incursions and 6275 nonstandard geometry locations. At the end of FY19, there were 134 locations in the RIM inventory at 76 airports and 44 locations mitigated since the program’s inception. Airports utilized a variety of mitigation strategies to eliminate the problematic geometry characteristics or reduce their effect at these locations. Mitigation strategies include modifications to airport geometry, changes to lighting, markings, or signage, or changes to procedures or operations.
