I am considering purchasing PowerFLARM Standard with Butterfly connector. Since most small aircrafts here in Norway don't have FLARM installed and don't have Mode S transponder, SD PowerFLARM will rely on Transponder Mode C signals with only altitude information. This is what SD calls bearingsless targets. According to the SD manual a green ring around my aircraft will indicate proximity and altitude. This is the same way PowerFLARM's own display shows this. However, the SD manual doesn't say how multiple bearingless targets are displayed.

So my question is: how are multiple bearingless targets displayed? Multiple rings? How is altitude information shown for each bearingless target?

From memory, I don't think PowerFlarm supports multiple bearingless targets. There is only one in the information sent to us.
