Advanced Aircraft Analysis

Advanced Aircraft Analysis (AAA) is the industry standard aircraft design, stability, and control analysis software. With installations in over 45 countries, AAA is being used by major aeronautical engineering universities, aircraft manufacturers, and military organizations worldwide.

AAA provides a powerful framework to support the iterative and non-unique process of aircraft preliminary design. The AAA program allows students and preliminary design engineers to take an aircraft configuration from early weight sizing through open loop and closed loop dynamic stability and sensitivity analysis, while working within regulatory and cost constraints.

AAA is used for preliminary, Class II design and stability and control analysis of new and existing airplanes. Class II design incorporates detailed weight & balance, aerodynamics, stability & control calculations including trim analysis and flying qualities used in conjunction with the preliminary design sequence. Class II design accounts for power plant installation, landing gear disposition and component locations on the airplane. Class II uses more sophisticated methods than Class I and requires more detailed information of the airplane to be known. The accuracy of Class II methods is therefore greater than Class I methods.

AAA can be used for small airplanes all the way up to military and transport airplanes. The program is designed to assist in the design learning process while reserving for the user the individual creative judgment which is essential to the process of airplane design.

Advanced Aircraft Analysis (AAA) applies to most fixed wing configurations (civil and military aircraft) and allows design engineers to rapidly evolve an airplane configuration from weight sizing through detailed performance calculations and cost estimations.

All applicable performance and flying quality regulations are available in the AAA program. This provides the designer with an instant appraisal of the status of the design relative to these regulations.

AAA uses both British and S.I. units. The program can switch between both units within the same project. The calculator allows temporary change of units (for instance enter engine power in HP, while the project is in SI units and needs kW).

The design methodology used in Advanced Aircraft Analysis (AAA) is based on Airplane Design I-VIII, Airplane Flight Dynamics and Automatic Flight Controls, Parts I and II, by Dr. Jan Roskam, and Airplane Aerodynamics and Performance, by Dr. C.T. Lan and Dr. Jan Roskam. AAA incorporates the methods, statistical databases, formulas and relevant illustrations and drawings from these references. Visit our online store to purchase these and other high-quality aeronautics resources.

Advanced Aircraft Analysis (AAA) has been under development for more than 20 years, at a cost of over 60,000 man hours and more than three million dollars. AAA Version 3.12 has:

• 277,464 lines of code
• 4,501 unique parameters
• 9,850 variables on all windows
• 2,845 output parameters
• 561 different series of calculations
• 498 different I/O windows
• 120 different plots
• 95 different tables

Several Reasons to Purchase Advanced Aircraft Analysis (AAA):

1. You will spend more in a two-month period developing your own in-house code, in man-hour cost alone, than if you purchased one commercial license of AAA.

2. You will save over 80% in man-hour costs using AAA for preliminary design, versus using handbook and spreadsheet calculations.

3. Using AAA will greatly reduce calculation errors.

4. Being able to use multiple flight conditions (forward c.g., aft c.g., low speed, high speed, flaps up, flaps down, etc.) is a unique feature of AAA and significantly reduces time to track data and prevent potential errors.

5. The "Recalculate All" feature in AAA is a significant time savings tool and allows you to export the data for different flight conditions into an Excel or text file. All plots for trim diagram, for example, can be saved as separate graphics files, using this same feature.

6. We use AAA for our airplane design consulting services. We are constantly updating and refining the methods used, based on our research and wind tunnel tests that we perform. This leads to regular software version updates, which benefits all of our software clients.

Advanced Aircraft Analysis Modules

Advanced Aircraft Analysis consists of 10 independent modules. Each module is designed to perform those tasks necessary to evaluate the characteristics of a given aircraft at each stage of the preliminary design. Download the AAA module descriptions (pdf)

Software License and Evaluation

Advanced Aircraft Analysis (AAA) can be installed as a Node Locked License (AAA is only valid on the PC the software is installed on) or Floating License (AAA can be used on any computer in the network).

Software purchase will include CD-ROM, WIBU Key (Universal Serial Bus), printed user's manual and 12-months software maintenance (technical support, service releases and upgrades). We offer educational and multiple license discounts.

We also offer a limited time and functioning version of AAA for trial use and evaluation. You cannot save, print, copy, paste or export files. AAA is limited to one flight condition and is valid for 30 days. Due to America Online's network procedures, AOL users may not be able to download AAA. Request Software Pricing and Evaluation

AAA Student License

If you are currently enrolled as an aeronautical engineering student, you can purchase a 12-Month Student License of AAA. Software is fully functional and can be renewed after 12 months. Software can only be used for class work and university sponsored design projects. Software cannot be installed in a University lab, shared with or transferred to another student. Applicant must have a valid student ID to qualify for student pricing. Software purchase will include AAA and user's manual (pdf) on CD-ROM and WIBU Key. AAA can be installed on registrant's personal PC and laptop only. Purchase AAA Student License ($150.00).

AAA Reader

The AAA Reader is a standalone program that allows users that do not have AAA to view data stored in AAA files. The AAA Reader is available as a free download from our website. Download FREE AAA Reader.

AAA Atmosphere Module

The Atmosphere, from AAA, can be used to calculate the Mach number, Reynold’s number, Temperature, Kinematic Viscosity, Density, Dynamic Pressure and speed of sound along with density, pressure and temperature ratios at various altitudes and speeds. The user can switch between British and SI units. This is a very handy tool for aeronautical students and engineers, is included in AAA,and is available as a free download from our website.
