I’m calling the METAR method such as for the ICAO of KRIC. It’s pulling data an hour old. This was reported to me by a customer using my app, I verified this against aviationweather.gov/adds/metars/ that in fact the FlightAware data is not the most current as of the request.
I don’t have the data anymore as the time I checked per my customers report FlightAware was one hour older than AviationWeather’s data. I’m using the flightware service so I’m not sure if that’s cached and may be different than the web page check of the data?
