I am curious if anyone knows the following - on a modern widebody aircraft, what are the common data rates observed between the flying aircraft and the manufacturer or the airline itself?
I've done a bit of searching and found one company (LMS) that provides a data acquisition system during testing; I read that they had the capability of collecting data from roughly 136 sensors and transducers, with each sensor having a dynamic range of 24 bits, with sample frequencies of 80kHz. This works out to roughly 32MB/sec, or ~120GB/hour (1TB/8 hours).
For operational aircraft, how many sensors readings are transmitted back to the manufacturer, at what resolution, and at what frequency?
The reason I ask? I recently read some information in the context of discussing "Big Data" problems and some outrageous figures were being reported. Specifically: "For every 30 minutes that a Boeing jet engine runs, the system creates 10 terabytes of operations information".
This statement is tragic on many levels ...
In any event, thanks for any info or insight.
