I installed the current iFlyEFB on the new TriplTek tablet and took it flying today and noticed the glide ring for the first time. I decided to try it out. I was 3000ft. AGL - flew till our airport was just under the edge of the ring and pulled power. I set up my usual glide speed and ended up needing to slip the last bit before landing to make the first 1/3rd. of the runway (2600 ft). I'm impressed! I think the glide ring is a very valuable addition to iFlyEFB - Thanks!
