Websites Displaying Airspeed

[JScriven]

Hi everyone

I'm looking for information about the airspeed/heading of planes. As I understand it, FR24 displays groundspeed and track, although IAS is available through Mode-S. A few of the other radar spotting sites display simply "speed". Does anyone know of any sites that give IAS data?

Thanks

Also, can I confirm that IAS is transmitted on Mode-S? If I were to buy a receiver, could I downlink the data that way. The reason I'm asking is I'm trying to complete a research project looking at the viability of using Mode-S data for various applications.
