Powerful and flexible, RDS^win is over 100,000 lines of original code. It has over 600 pulldown menu commands plus on-screen buttons and hot keys, and a complete pop-up PDF user's manual. RDS^win outputs analysis results and program data to popup boxes, text files, Windows printers, or directly to your spreadsheet, word processor, or internet browser. It has instant graphing capabilities, formatted results output, and much more.

RDS^win has its own, integral 3-D CAD module that was developed specifically for the design of new aerospace vehicles. It "knows what an airplane is" and has numerous features that allow rapid creation and modification of aircraft and spacecraft components. A new design can be developed in as little as an hour (1-2 days is more typical). Once the design is created, this Design Layout Module automatically extracts the important geometric information and loads it into the appropriate analysis module via an automatically-created RDS TAB file, which is also useful as a source of geometric information for reporting purposes.

RDS^win rapidly analyzes an aircraft's aerodynamics, weights, propulsion, longitudinal stability, and cost, and performs mission sizing and range/loiter analysis. RDS^win has complete performance analysis including takeoff, landing, rate of climb, Ps, fs, turn rate, and acceleration. RDS^win provides graphical output for drag polars, L/D ratio, thrust curves, flight envelope, range parameter, and more. The Professional version also has a built-in optimization capability including classic Carpet Plots and a full Multidisciplinary Design Optimization (MDO). RDS^win works equally well in Metric and FPS units, and all inputs and outputs - past and present - can be instantly switched from one to the other.
