How's things at = Shadetree?

If you are thinking that the ROI is about = fuel savings you have missed the point. While that is nice and = adds up over time the real return is on what you learn about your engine = , its operation, and its maintenance. For example, the stuff on = engine monitors could easily save you the tuition cost in one flight, = save the engine or you and Janet's butts. <g> The = section on detonation and preignition, how to recognize them and what to = do about them is not about fuel saving... it's about life = saving.

While the APS class is known as the "LOP = School", that is only about 5% of the course. (We teach = optimal mixture management whether ROP or = LOP.)

(BTW, forwarded your email about the reunion = to Pat)

I’m not convinced of the = ROI for spending $995 on this course in my particular case. As an = example, for my LNC2 with an IO-360, if I burn 9 gph running ROP and 8.5 = gph running LOP (best case scenario), how long does it take to recover = the expense? To keep it simple, let’s say I spend = $6/gal. So, that’s $995 x gal/$6 / 0.5gph =3D 331.7 hrs, or = about 3 years of flying. So, the question becomes, is it worth all = the hub bub? Again, for me, I think not. For you guys with = the high burn rates, maybe so. But what is your actual hourly = saving and is it worth the additional stress on your engines for the = potentially much lower TBO? You decide and your mileage may = vary.

If you operate your engine ROP at high power = settings you have a much greater chance of damaging your engine than by = anything you might do = LOP.

The next Live APS class is = October 7-9.
