Somebody told me the
Kinetik box shows
position of all Mode S traffic.
How does that work, for aircraft with Elementary Mode S which is not permitted to radiate that data? Non-EU reg Mode S aircraft will probably be radiating it (because the "Elementary" v. "Enhanced" Mode S is a purely European invention) but an EU reg
banned it for local reg ones.
Such a box would benefit ATC situational awareness but - like London Information which has similar unofficial radar access - they would still not be able to legally make a radio call to an aircraft which they thought would benefit from the information.
