In 11-17 January 1995 issue of _Flight International_ there is an article titled ``Lessons from the Cockpit.'' A brief history of "glass cockpit" was given. Much of the article dealt with the German pilot union's reactions to a number of recent Airbus's mishaps (namely, Lufthansa's 93 A320 crash in Warsaw, China Airlines' 94 A300-600 crash in Nagoya, TAROM's 94 A310 near crash near Paris-Orly, Air Inter's 92 A320 crash, and Airbus's own A330 test-flight crash in 94). Interestingly, it was mentioned in the article that there was a Service Bulletin issued by Airbus in Dec 93 that the French authority (DGAC) classified as a mandatory airworthiness directive (AD) requiring French operators to incorporate the autopilot-software modifications for the A300/310 in two years. As speculated in the article that if China Airlines had implemented the modifications, the accident might have been avoided. In conclusion, the article said (a direct quote): Meanwhile, Airbus is gaining operational experience every day with DFBW (Digital Fly-By-Wire), using a digital system which is not designed to make the pilot feel as if he is flying a traditional aeroplane. Boeing is about to enter the operational ring with its 777, an aircraft which artificially reproduces for the pilots the characteristics of a traditionally controlled aeroplane, although it is flow using digital-control laws. Is Boeing right in its premise that reality must be disguised to achieve the best possible man-machine interface? Or, there being no prefect solution, do both companies' approaches have an equal chance of being effective? As the world progresses into digital future, only time will tell.
