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.)

I=92m 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=92s say I spend $6/gal. So, that=92s $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?

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.
