FEAFAA (Finite Element Analysis - FAA) was developed by the FAA Airport Technology R&D Branch as a stand-alone tool for 3D finite element analysis of multiple-slab rigid airport pavements and overlays. It is useful for computing accurate responses (stresses, strains and deflections) of rigid pavement structures to individual aircraft landing gear loads. FEAFAA is not intended for use as an FAA design procedure. For performing pavement thickness designs in conformance with FAA standards, please download FAARFIELD 1.305.

FEAFAA makes use of the 3D finite element program NIKE3D, originally developed by the U.S. Dept. of Energy Lawrence Livermore National Laboratory (LLNL). This program has been modified by the FAA for pavement analysis and is distributed according to terms of a Software Agreement between the FAA and LLNL. 

Note: Minimum requirements to run FEAFAA 2.0 are Windows XP or higher with 512MB of RAM. However, it is recommended that you have Windows 7 or higher with 4.0 GB of RAM for best performance. FEAFAA 2.0 is compiled to run on 32-bit or 64-bit operating systems.
