ADS-B OUT Tips by Darryl Ramm
ADS-B Out Info -- think about ADS-B out installs over this Winter

GPS Antenna not included, The Trig TA50 is the recommended GPS antenna.

A small price for safety and performance

Flying in busy skies, or in remote areas means that many pilots want to exploit the visibility and safety that ADS-B provides. ADS-B In traffic receivers, used in general aviation today, allow a pilot to view ADS-B Out equipped aircraft on a cockpit display.

However, most traffic receivers will only display aircraft traffic that generate a non-zero quality indicator, (also referred to as SIL 1). In contrast a zero quality indicator (referred to as SIL 0) ADS-B Out, is ignored and not displayed on a traffic display – rendering an aircraft invisible.

Using lower grade SIL 0 equipment your aircraft will be hidden from view. But you don’t have to compromise your electronic visibility when you fly with Trig. A TN72 will be visible across all ADS-B In traffic platforms. By installing a TN72 with your Trig transponder you will have a certified collision avoidance safety benefit – that’s easy to install and proven to work with Trig transponders.

The TN72 will commence shipping in September 2017.


  • Interfaces with Trig transponder to provide ADS-B Out
  • GPS receiver – certified to TSO-C199
  • Enhances visibility and safety
  • Collision avoidance (uses non zero quality indicators)
  • Enables live tracking of aircraft
  • Triggers traffic information services (TIS-B only available in U.S.)
  • Low cost and light weight
  • Global Trig warranty


In all non mandatory airspace, or where equipage is voluntary, the TN72 is an attractive and practical ADS-B position source. It meets the FAA’s TSO-C199 certification standard for a Traffic Awareness Beacon System, known as TABS for short. Trig’s TN72 supports current and future air to air collision avoidance and situational awareness applications. This enhanced visibility can be useful for tracking club aircraft in real time, improving safety in the circuit and reducing the risk of air-to-air collision.

In countries where ADS-B airspace is mandated, operation in 2020 airspace usually requires full compliance with TSO-C145 GPS technology, our TN70. It’s worth knowing that in the U.S. to receive a full traffic service from ADS-B ground stations, aircraft must be ADS-B Out equipped. The TN72 is well suited to glider pilots, with a Trig transponder a full traffic service will  be triggered (an ADS-B traffic receiver is required). Powered pilots can also use the TN72 as a highly cost effective way  to trigger traffic information outside of 2020 airspace.

Trig are leaders in ADS-B (Automatic Dependant Surveillance Broadcast) technology, we were the first company in the world to meet FAA TSO C-166b the latest standard for ADS-B transponders. Every Trig transponder is Mode S, but also ADS-B capable. Once installed ADS-B equipment transmits your aircraft’s precise location directly to other ADS-B equipped aircraft, improving your electronic visibility and safety.
