| Backcalculation Software (BAKFAA 3.3.0) | For backcalculating FWD data and computing airport pavement load responses by layered elastic analysis. Use with AC 150/5370-11, Use of Nondestructive Testing Devices in the Evaluation of Airport Pavements. | 6/2020 | 
| Geodetic Calculator (Zip) | Updated version of GEO83 | |
| Runway Exit Design Interactive Model V4 (REDIM-V4) | REDIM is a computer model developed to locate and design high-speed runway exits at airports. The model uses kinematic equations to characterize the aircraft landing dynamics and a polynomial-time dynamic programming algorithm to find the optimal locations of the high-speed exits. The objective of the optimization algorithm is to minimize the weighted average runway occupancy time (ROT) of an aircraft mix selected by the user. A database of aircraft characteristics for four terminal Aircraft Approach Categories (AAC) has been included in the model to facilitate its use in a large variety of airport environments and conditions. The database file relieves the user's data-input burden, specially when the aircraft mix consists of many different types of aircraft. The program is developed to be used as a design and a planning instrument by engineers. Hence, considerable effort has been devoted to user interface such as menu system, interactive data editing, and graphical and tabular outputs. | 11/2022 |
