Amazon.com description: Product Description: The companion RDS-STUDENT aircraft design software is a valuable complement to the text. RDS-STUDENT incorporates the design and analysis methods of the book in menu-driven, easy-to-use modules. Like the book, the program is metric-friendly and all inputs and outputs can be interchanged between metric and fps units with the press of a button. An extensive user’s manual is provided with the software, along with the complete data files used for the Lightweight Supercruise Fighter design example in the back of the book. RDS-Student has been extensively revised for the 4th edition of the book. RDS-STUDENT runs on any PC-compatible system and runs on any version of Windows or DOS.
