For many years the Air Force, Navy, NASA and educational institutions have sponsored the development of computer software that is useful to aeronautical engineers, airplane designers, and aviation technicians. Public Domain Aeronautical Software (PDAS) was founded to make this treasure house of valuable software available to the aeronautical community for use on desktop computers. These programs include descriptions and complete public domain source code. All are downloadable free of charge from this web site, and a CD-ROM or USB thumbdrive of the complete collection is offered for sale at $99. Many programs have sample cases (both input and output). The source code is not copyrighted and may used in whole or in part in any of your aeronautical studies. Most were developed under NASA or DOD sponsorship, but some are contributions from individual authors and all have significant value added by PDAS.
