The maneuver loads part of aircraft design has evolved from a relatively clean cut, predetermined analysis to a long iterative process which gradually utilizes flight test information to expand the flight envelopes. It is a process that is also much more demanding because it involves the reliability of the flight control system (FCS) in proving structural integrity. The conclusions of the study were that: there is no consistent set of airworthiness criteria which fully covers maneuver loads of agile aircraft; attempts to update the existing criteria to embrace the vast possibilities of active control systems (ACT) are only partially successful; proof of airwothiness of aircraft with ACT has become more demanding since the load influencing functions of the FCS are directly safety critical and must be analysed for failure to the same quantitative criteria as the structure itself; the existing criteria can and should be used for initial design to define the airframe; certification needs to become adaptive to reflect a long period of testing and FCS changes.
