How “current” is the weather overlay relative to the FlightAware flight track? In other words…if the flight track data is delayed by 15 minutes is the weather data also delayed by 15 minutes? I.E. is the weather radar “in sync” with the flight track?
Great question, I have always wondered that myself. Thanks for the answer.
Welcome to Flightaware!
One follow up question, When you guys generate a flight track pic, is the midpoint weather unique to that flight? Or do you just pull the weather radar data from a “master” radar mosaic. I have wondered what a massive amount of data it must be for a weather radar snapshot of EVERY single IFR flight.
I’m not on the mapping team, but I suppose it’s the same amount of data. We archive the weather every 15 minutes onto a cluster of weather servers and store every weather update ever (35,000/year). Each weather update is 15MB, so that’s 525GB/yr. The storage servers at FlightAware each have 10TB (10,000GB) usable storage.
The map server you’re talking to may have the weather locally or it pulls the correct weather from a nearby weather cluster over gigabit ethernet and zooms it to the right area and underlays it on the map.
Oh, and for people that block ads, remember that we maintain all this kind of infrastructure at several data centers in multiple countries.
