Re,
If reading the flight data is so nebulus then why are some airlines routinely using it to monitor performance of all pilots (FOQA)?
What about the flight data is inaccurate?
The data is easy for airlines to read because they invest tons of money, (hundreds of thousands, in some case millions) in their FOQA programs, which includes the proprietary software which is capable of reading the information that comes from the SSFDR.
This is not "Excel spreadsheet" work, nor is it "hacker's" work.
If, as I take it, you are speaking for those who would have this data on their laptops etc so they can for themselves make up their own minds as to the veridicality of the SSFDR data, please tell me what you know about flight data analysis - not in general; the details, so at least you may establish yourself as someone who comprehends what is being demanded here.
