Comparing STCs

We use separate STCs to provide ADS-B for legacy Learjets both with and without TCAS II, which offer state-of-the-art equipment and full ADS-B functionality. The key difference is that ST02230SE is installed in aircraft without TCAS-II, while ST02455SE provides installation compatibilities in aircraft with TCAS-II. Both ST02230SE and ST02455SE have the option of ADS-B “In”, making it easy to take advantage of the subscription-free weather and traffic information offered by ensuring customers can send FIS-B and TIS-B data to common, cost-effective devices such as tablets.
