TN72 – AFFORDABLE ADS-B
The TN72 GPS Position Source brings ADS-B Out capabilities to your Trig transponder. Light weight and easy to fit, the highly affordable TN72 uses certified technology making you visible to all ADS-B In traffic devices.
Flying in busy skies with a TN72 will reduce your risk of collision and improve flight safety. In the U.S. the TN72 used as your ADS-B Out solution will trigger a full traffic service uplink – received using ADS-B In equipment.
When using a TN72 there are two different ways to set up your Trig transponder (shown below). The TN72 hardware is the same in either installation.
TN72 GPS – X configuration uses SIL 3 in the transponder settings, and fully satisfies the technical requirements of FAR 91.227 for 2020 compliance. Light-sport, experimental and homebuilt pilots who have fitted a TN72 are now flying inside ADS-B airspace and have passed FAA compliance checks with flying colours.
TN72 GPS – TABS (Traffic Awareness Beacon System) configuration uses SIL 1 in the transponder settings. TABS is the FAA technical standard that enables voluntary equipage of ADS-B Out. The TN72 using TABS is ideal for certified gliders and Part 23 aircraft, operating outside of U.S. 2020 rule ADS-B airspace as a means of enhancing visibility and triggering traffic.
Glider customers in the U.S. looking to get ADS-B equipped may wish to see our ADS-B gliding guidance document this highlights equipment and regulations, for both certified and experimental gliders. In Europe and other countries, where the use of ADS-B equipment is voluntary, then the TN72 TABS configuration is the best way to remain visible to other traffic.
Installing a TN72 and suitable GPS antenna is a small price to pay for enhanced visibility and peace of mind.
• Simple ADS-B Out upgrade for all Trig transponders
• Suitable for experimental aircraft / gliders and light-sport pilots for 2020 compliance in U.S.
• Safer – visible on all ADS-B In systems
• Enables live tracking of aircraft (with suitable ADS-B In equipment)
• Triggers traffic information services (TIS-B only available in U.S.)
• Low cost and light weight
• Two year world wide warranty
The 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.
The TA70 certified antenna is designed to compliment the TN72. In installations where a smaller antenna is required then suitable alternatives can be used, see our FAQ section. In countries where ADS-B airspace is mandated, operation in ADS-B airspace by certified types usually requires full compliance with TSO-C145 GPS technology, our TN70.
Trig are leaders in ADS-B technology (Automatic Dependant Surveillance Broadcast) and the first company in the world to meet FAA TSO-C166b, the latest standard for ADS-B transponders. Every Trig transponder is Mode S, but also ADS-B Out 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.
