Simulation during control program development
Mahcinbird, HN39
I would hope that simulator programs would extend into regions beyond normal airframe testing limits - based on wind tunnel test data. One can expect aircraft to, on rare occasion, inadvertently experience excursions into extreme realms even with highly trained crews and state of the art instrumentation focused on avoiding it - as nature is always capable of surprising us. Take for instance the temperature fluctuations encountered by the A340 and implications for exceeding mach limit. One would expect such an event could be anticipated during control design but it probably would not be the subject of airframe testing. Thus it seems appropriate to do simulator modeling (during design) - to test the control design for the response to such an event. Perhaps that range of information is only available to A300 Engineering in their simulator.
