Well, there is one device that is installed in 25,000 gliders worldwide and one that is installed in...how many? 500? People can decide which is the tail and which is the dog when it comes to wagging. I think if I showed up in most European countries with an electrical device requiring 110 volts I would not get agreement that the entire continent is incompatible and needs to change to 110 volts.

The TAdvisor, and probably the OGN devices soon, are not worst than flarm to do this job.

That isn't even how they talk about themselves.

Here is what T-Advisor says about the themselves: "The functioning idea of the T-Advisor is not the one of an Anticollision or Collision Avoidance System, rather the one of the Traffic Advisor, an Early Warning System."

OGN's main purpose is tracking, not collision detection. Here is what they say about themselves: "The objective of the Open Glider Network is to create and maintain a unified tracking platform for gliders and other GA aircraft. Currently OGN focuses on tracking aircraft equipped with FLARM, FLARM-compatible devices or OGN tracker."

Hair-splitting and straw-manning are not a productive ways to advance the conversation.
