Mode S has send/receive capabilities and GARMIN will be using this ability to send the same primary radar information ATC sees up to the aircraft to be displayed on the GARMIN 400/500 series units. Known as T.I.S., this TRAFFIC INFORMATION is received from the ATC system and therefore requires the aircraft to be within a radar environment.
With the intro of the GTX 327, Garmin revolutionizes a part of the panel that has been long overlooked. This full-featured, TSO certified transponder brings a unique level of functionality and utility to your airplane. Its solid state transmitter provides 200 watts nominal power output and eliminates the need for a cavity tube which will eventually fail and require expensive replacement. And since the GTX327 design is 100% solid state there is no warm up time, lower power consumption and lower heat emission.
The GTX 320A is a full featured, compact, panel mounted Class 1A transponder. The GTX 320A's solid state transmitter provides 200 watts nominal power output eliminating the need for a cavity tube that can degrade with time, fail, or require expensive replacement. 100% solid state also means no warm up time, reduced power consumption and heat for longer service life.
