The "study sim" is a genre of simulation games that focuses on modelling an aircraft's systems as accurately as possible. Advancing computer technology made this possible, with the development of highly detailed models that improved upon the fidelity of avionics, weapons systems, physics, flight models, graphics, etc. and allowed for fully interactive cockpits where virtually every control was mapped and functional. This was important as modern jet combat aircraft and helicopters have a variety of complex electronic and weapon systems that are specific to a particular aircraft.
