I see the letters to Messer's McCormick and Truss both infer Flightradar24 displays all aircraft.
Any ATC confirm what percentage of aircraft outside the "J" curve it displays vs reality? Or have a TAAATS screen grab of a time period the same as Flightradar24 for a comparison?
Closest I can come up with is this, which according to a Google search comes from an Airservices presentation to the Engineers Australia Southern Highlands and Tablelands Regional Group conference. While 2 years old it does show far more traffic outside the "J" curve than Flightradar24 does now.
I also stumbled across this. Quite cute I thought.
