think about it the backbone of our airlines were designed in the 60's and 70's with the 737 designed in 1965 the 747 designed in 1963, the 767 designed in 1970, the 777 was designed in 1988 basicly our airfleet was all designed before the windows pc. thats why there arent Pc's in there 
I dont think people realize how old the fleet of jets are in the united states, the good news is boeing got certified for its boeing 787 dreamliner wich after many delays and 6 years behind on its 827 orders will be starting delivery in japan this month and looks to replace both the aging 747 and 767 fleets |
This ignores that avionics are updated constantly. Just because an airframe was designedin 1965, doesn't mean that the electronics inside are from 1965. Hell, the engines aren't even from 1965. It's very common for the overall weight of an aircraft to increase over it's lifetime as equipment and capabilities get upgraded, necessitating an engine retrofit in some cases.
