Hi
How must an aircraft be equipped to be visible on Flightradar24 if it doesn't have an ADS-B transponder? and what modes has to be enabled as a minimum?
More specifically:
Is the Mode S Acquisition Squitter used for MLAT calculations? (Acquisition Squitter contains only the Mode S ICAO address and it is the basic Mode S squitter used by TCAS equipped aircrafts). Or is it only replies from ground interrogations (Mode S all-call etc) that are used for MLAT.
Is the Mode A/C replies used for MLAT calculations (for aircrafts without Mode S transponder)?
