+xSkyDemon uses TCAS-like conflict detection algorithms. An urgency situation is measured in terms of the number of seconds before a conflict is likely. Like TCAS, this is not a fixed number but variable depending on the nature of the closing situation, but will be between 30 and 60 seconds.
Thanks Tim.
This is important, because the glider fraternity all say that Flarm is better, because it gives a conflict alert. But on Sky Demon, PAW is doing exactly the same.
Thanks,
