The controls , with their arrays of complicated dials , were generally designed for a three - man : two pilots and an . A typical trans - port aircraft from this period had more than 100 instruments and controls , the most important of which were packed with bars , and symbols . All of these jostled for space on the various instrument panels , and competed for the pilot ? s attention . Research aimed at a solution to this problem , conducted in particular by NASA in the United States , led to the development of devices capable of processing data , and the raw information provided by aircraft systems , and it into an easily understandable synthetic image . This development was only possible be - cause of a fundamental change in the type of processed by onboard systems . instruments , based on information , provided indications that were linked to the associated physical ( for example air pressure , , or the position of a gyroscope ) . Digital information , on the other hand , results from the conversion of a measurement into code by means of an analogue - digital . The digitisation of the physical data required for flight control and , as well as for more general operational and informational , led to a profound change in aircraft from the 1970s onwards . Thanks to improvements in electronics and computer , data could now be converted from analogue to digital format , processed by , and displayed on computer - type screens in the cockpit .
