I've found the Aviation SE to be a really interesting read so far, I'm excited to be here! I'm fairly new, but I'm also old!
What are the inputs for TASAR to crunch flight path optimization? Is it taking a look at the aircraft performance model, wind and weather, and ADS-B IN? Maybe TCAS-II traffic info? Would the weather data come from the onboard WXRadar or ground data?
I've read a few data-points that the long range weather info pilots tend to use is from received data (maybe ground radar or sat based weather data? both?), but the data is delayed to the point of being less useful, would the weather data need to take inputs from both Weather RADAR and NEXRAD type inputs?
