Many of the pages referred to by this site are Acrobat PDF files. The link below will take you to the Accessibility pages of Adobe Acrobat, where they have free tools available for making PDF files accessible using your browser. These are locally created materials or, more frequently, locally rehosted copies of material from other sites. The local copies are then particularly useful within the Air University community for speedy access, and to serve as alternate sources for others. Local copies are only of material released by originators for public viewing.
Local copies are for educational use only.
However, some may be copyrighted and available for free use only within government organizations or government web pages.
