-- A review of the Garmin GTX 330 Mode S (aviation radar) transponder
I spent Too Much time listening to the ATC radio comms United copies to its inflight audio entertainment system on the Christmas trip home. (To the point I started wondering if I wrote down the directions given on approach and noted the times, how accurately I could plot an approach on a map afterwards.) So I started looking into all the nifty new things air traffic control can do with modern technology. (By contrast, the technology behind the Instrument Landing System dates to before World War II, though refined.)
