The software for the ARTISTS' PERSPECTIVE MODELER (APM) system described in this User's Guide might no longer be available on a CD. It contained two spreadsheet programs; a basic "clean" one, and another with the input and output data for the subject airplane in the User's Guide. Also on the disk wa an "Offsets Generator" program and instruction for its use.

The APM software requires Microsoft Excel 97 or later. It's for use on a PC but it has also been tested on Excel X for Macintosh.
