The accuracy of Class II methods is therefore greater than Class I methods.ĪAA can be used for small airplanes all the way up to military and transport airplanes. Class II uses more sophisticated methods than Class I and requires more detailed information of the airplane to be known. Class II design accounts for power plant installation, landing gear disposition and component locations on the airplane. 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. 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.ĪAA is used for preliminary, Class II design and stability and control analysis of new and existing airplanes. With installations in over 45 countries, AAA is being used by major aeronautical engineering universities, aircraft manufacturers, and military organizations worldwide.ĪAA provides a powerful framework to support the iterative and non-unique process of aircraft preliminary design. Advanced Aircraft Analysis (AAA) is the industry standard aircraft design, stability, and control analysis software.
