Section 4: Pilot’s Guide
4.1 Using the GTX 330
Standard operating procedures apply to GTX 330 transponders when used with GRT EFIS systems.
Please refer to the Garmin GTX 330 user manual for transponder operating instructions.
4.2 Traffic Display Icon
When the display unit is programmed to the specifications in Section 3, traffic alerts will pop up
on the map and/or primary flight display automatically when within range of radar-based TIS
(Traffic Information Service) or ADS-B when equipped with an ADS-B receiver.
ADS-B and TIS traffic alerts use the same symbols. Note that if target aircraft do not have Mode C
capability, altitude information is omitted from the icon.
In the example given here, your aircraft is the large icon in the
center of the circle. The target traffic is at your 1 o’clock position,
700 feet above you, climbing at least 500 fpm, and heading nearly
the same direction.
