Here's one for an RV9.

I do not recall having encountered one before, as a pilot nor A&P (then again I was more "P" than "A"), and it seems to me to be well within the "designers" realm. However, I would say that a builder, is a liaison between designer and pilot. Here we wear two hats,..yes? Quite obviously, it would be more than useful to have a working knowledge of this.

Thank you for bringing this to light Hank, I will study it further.

As for the comment regarding full power climb, I had read (somewhere), that most test flight engine failures happen with the first power reduction.

More research on the matter is required, but it occurred to me that since Vy is the difference between engine power and the power required to overcome the aircraft's drag, then you would likely benefit from both the lowered speed and performance climb.
