Curious as to how ADS-B data is distributed and shared.
Appreciate the FA site says data may be delayed by 30 seconds or more but am wondering; do FA and Flightradar24 use the same data sources? Reason I ask is that Flightradar24 appears to be real time whereas FA is definitely delayed - unless of course viewing Skyview on my own R-pi.
This discrepancy came to light when I was speaking to a friend in US (I am in UK) and telling her when aircraft would pass overhead, the FA map was too delayed for this to be accurate whereas FR24 appeared to be real time.
Not an issue, just curious.
