Specialized analysis and modeling tools will be required to evaluate the complex flight control systems being considered for future generation aircraft. This paper documents a proven systematic approach for integrating several modem modeling and analysis techniques into one evaluation methodology. The evaluation methodology has been used successfully to evaluate several production fighter aircraft and rotorcraft flight control systems. The modeling tools discussed include: linear model extraction from nonlinear simulations, linear model build-up, and equivalent system model reduction. Efficient techniques for validating and comparing complex linear models are also presented. The stability and handling qualities analysis tools used in the evaluation methodology and described herein result in direct comparisons of control system characteristics with military flying qualities and flight control system specifications. Tool and technique descriptions are supplemented by lessons learned from previous flight control evaluations.
