Question for the Geeks:
Since modern aircraft are apparently connected full time/real time by satellite and other methods of data communication, why aren’t the Flight Data Recorders given a channel to transmit data ?
I mean, the actual amount of data is really fairly small. A few Kilobytes a second for flight instrumentation and engine data, a few more for cockpit voice and radio traffic.
Really a fairly small amount f data, considering the connections most modern aricraft have today to send and receive data from their systems.
SO why? Why don’t we have a portion of one of these channels set aside? Why don’t we have the last moments of cockpit and voice data and radio traffic stored on someone’s server where we could get to it to see what the pilots were seeing and hearinf and saying to each other?
Sure, these systems could be disabled, and the Flight Data Recorders (the “Black Boxes” which are actually bright orange) would be the only backup. But if they were disabled, we’d know that something was up….
