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.
The traffic will be displayed on the moving
map using standard traffic symbols, white targets (less of a
threat) and yellow targets shown as objects of immediate concern
with their respective altitudes and trend info (ascent or descent).
An added safety bonus is having these targets shown with "VECTOR
LINES". These lines will extend from the traffic symbols
showing the direction of travel, thereby eliminating the need
for the pilot to "study" the screen in order to disseminate
which aircraft is coming in his direction, etc.
The GTX 330 will also have voice capability
enabling the pilot to "hear" the warnings regarding
traffic of concern through their headset or over the cabin speaker.
Adding to the list of useful features,
GARMIN has included an ALTITUDE ALERTER whereby the pilot merely
sets the preferred altitude and the transponder will advise via
voice and visual warnings if the aircraft ascends or descends
through the programmed altitude buffer. The altitude buffer (100ft.,
200ft. etc.) can be set for the pilots comfort level of choice.
In addition, the transponder will display
"indicated altitude" (the altitude the encoder is reporting),
count-up, count-down timers and flight time.
