I already use a transponder S mode. Why should I need SafeSky?

The S mode transponder is only detected by secondary surveillance radars (SSR), and therefore air traffic control, as well as by aircraft equipped with a TCAS (Traffic Collision Avoidance System). To date, the majority of aircraft flying between 0 and 5,000 feet is not equipped with this type of expensive equipment. Therefore, being equipped with an S mode does not protect you from a mid-air collision with other air users.

SafeSky aggregates most of the ADS-B, FLARM and OGN traffic, in addition to its own traffic, and is therefore today the most complete platform to SEE and BE SEEN. Discussions are ongoing to integrate S mode traffic into the SafeSky interface in the medium term.
