Maybe this is a well known technique, but I just finished my BFR today in a C152. As part of an engine failure simulation my instructor told me this airplane will automatically go to best glide speed by trimming to full up on the trim wheel. So, she cut power, I trimmed full up, and lo and behold it went right to best glide speed. I thought this was a fantastic thing to learn about this airplane and had never been exposed to this technique before. I have electric trim in my 9A, and although I'm not flying yet I'm interested in pursuing this setup if I can. So, have any of you set up your airplanes to take advantage of this technique?
