Find a recent edition of Jane’s all the World’s Aircraft in a technical or public library. Examine the data given in Table 2.1 for soft failures for the 6 aircraft types listed. From the book, determine the approximate number of electronic systems (aircraft avionics) for each of the aircraft that are computer-controlled (digital rather than analog). You may have to do some intelligent estimation to determine this number. One section in the book gives information on the avionics systems installed. Also, it may help to know that the U.S. companies (all mergers) that provide most of the avionics systems are Bendix/King/Allied, Sperry/Honeywell, and Collins/Rockwell. (Hint: You may have to visit the Web sites of the aircraft manufacturers or the avionics suppliers for more details.
(a) Plot the number of soft fails per aircraft versus the number of avionics systems on board. Comment on the results.
(b) It would be better to plot soft fails per aircraft versus the number of words of main memory for the avionics systems on board. Do you have any ideas on how you could obtain such data?
