eli5 Why can’t black boxes in Aeroplanes update data to a cloud throughout a flight or after a crash has occured? why do we need to find the physical box?
In: 846
Airplanes would need to constantly upload to most likely a satelite link, and that is expensive times 25,000 flights per day in the us. Crashes are also extremely rare, so its not a huge benefit compared to the cost when a black box. The black box is very reliable too, and can record data while a crash is occuring. During many crash scenarios a plan would lose a fragile satelite uplink, while a black box will record till the very end.
