A gaggle of gliders such as the one in that video would currently be treated separately. It’ll clearly be shown on the map and any sensible powered pilot would stay clear of it. If you powered on through or close to it, no spoken output or ground-based controller in the world is going to keep you safe, it’s eyes out constantly presumably! I have no gliding experience. The obvious potential enhancement in SkyDemon is to treat them all as one lump if sufficiently far away.
We’ve put some thought into what we do as you approach your destination airfield but those thoughts aren’t likely to turn into code in the first release. I personally like the idea of verbally advising the pilot how many aircraft are known about in the circuit, how many might also be joining, and notifying them if anyone on the ground lines up on the runway. But of course we are open to suggestions.
The Flarm driven voice systems I've used have a "warn once" option, where they warn you of new traffic that comes within range, but will then assume you keep eyes on it and not warn you (verbally) again for that traffic ID. You still get the "beep beep beep" warning if an imminent conflict is detected.
Even then in congested situations it gets overloaded, I'm not sure how you would build the algorithm but a "multiple contacts" output would be a good option.
