Chimbu Chuck,
How does this work??
Light aircraft don't (usually) have an ADC, or any other digitized IAS data, the Garmin 330 Mode S transponder plus GDL 90 GPS source has no IAS input of any kind, I was not aware that IAS was a required input into an ADS-B/C message??
I was referring to my day job, actually mostly night job, Boeing 767. We have been told that IAS is displayed to ATC - I remember thinking when told "FCK that SUCKS!!"
