One thought on “STX 165R :: What is the difference in benefits versus cost?”
If you have a Garmin 430/530 and only want to be compliant, any Mode S-ES would fit the need. But if you are only a VFR operator without a WAAS GPS installed and has an old Narco or KT76 Transponder asks, the cost effective solution would be a Freeflight or NAVWORX UAT and a Sandia STX 165 Transponder displayed on your MGL, GRT, DYNON or Advance Flight display.
