Frequently Asked Questions

What else will I need to be ADS-B compliant?
The TN70 certified GPS reciever provides a compliant position source for your ADS-B Out system. A Trig transponder will also be required – this acts as the hub of your ADS-B Out solution transmitting data to ground stations and other aircraft (which are ADS-B equipped). In the U.S. FAA FAR 91.227 requires your installation to be capable of identifying the correct phase of flight – this demands some means of Air-Ground determination. Our STC provides a simple means to meet the regulations using the latest transponder software with automatic air ground, this removes the need for a squat switch or air ground switch.
