First, of course I agree completely to operate successfully LOP you must have two things, GAMI injectors or any other precise fuel injectors and most importantly CHTs for each cylinder. That being said here is the other research you are looking for, I will stop at 3 links but the point is I have done plenty of research on this and LOP if you can do it is by far the way to go. I actually started a discussion on another forum about 6 months ago and spent days doing research on this for a course I am writing.


USA Best Economy

This gentlemen understands the economy of lean of peak, he doesn't realize that his CHTs are actually higher at ROP ops which I will show graphically in the next link. He says, "Trouble is, lean of peak can also result in cooler temperatures, along with reduced cylinder pressures. Braly and Roehl have spent the last 15 years fighting an uphill battle trying to prove that lean of peak is the way to go."


Lean of Peak

Take a look at the second two lines on the graph and note on the right side it points out that this section of the graph is for CHT. Now note the three vertical, left being ROP, center being peak, and right being LOP. You will see the CHTs on this graph confirm with that first link I posted for you. He also mentions, "I was pretty amazed at seeing that drop in temperatures occur. Make no mistake that heat is an enemy of any engine as is carbon buildup." This confirms the carbon build up I was referring to in a previous post, not addressing you but this topic in general.

Finally, the most important link. This link goes into detail on operations lean of peak as well as what is needed and why it is needed. It also explains a bit of detail about the thousands of pilots and organizations that have been using this for years while others avoided it as taboo. It is nothing more than an old wives tail that miss informed pilots have been adamantly against for years, it is time that changes. The article also explains the increase in engine longevity from operations LOP.


I was unable to find the article, maybe someone here will have more luck, on FADEC systems and their leaning procedure, LOP.


On a final note, when you look for articles on this topic pay attention to the time the article was written. There are still many old articles floating around on the internet against LOP and/or for 50 ROP. Almost anything in the last few years, particularly the last year in regards to leaning procedures drastically pushes for and tries to explain away fallacies behind LOP operations.

I hope this satisfies your curiosity for further information on the topic and by no means was I attempting to sound like a smart ass in these posts, so I am sorry if I did. I think I am going to include this each time as I often find my tone doesn't come across right on these forums.
