Joker10 and so what! You want to put a full suite of ProLine or Honeywell in your ol' warbird....I would say NO so I would also say NO for fitting the GTS860 in an Auster. SO how does price enter into fitting a TCAS or ADS-B Rx unit in a small lighty when an ADS-B Tx transponder and a non-TSO Rx unit will do just fine for a VFR pilot, all for under $5000.00AU.
Price is no longer an argument for fitment.
enough of the politics!
Keeping an eye on OSH for more announcments
