A36 turbo-normalized

I am a professional pilot with 50+ years of experience but, have never operated LOP. Have read all of Tornado Alleys information but still not completely sure about operation. I plan to operate WOT @ 2500 rpm. I always understood that you should operate engine at 75% or less power. According to TAT the fuel flow would have to be 15.1 gph to get 225 hp, or 75%. What if your EGT/TIT peaks, then lean further to get 60 degrees below peak, and this FF is above 15.1? What am I missing?

Reading the published information and asking questions is a good start. However, it sounds like you need some hands-on experience, suggest you employ a BPPP instructor that is keen on LOP ops. The reason for this would be two-fold.

First, it allows you to learn by observing the procedure, and doing it correctly.

Second, an experienced hand may also ferret out a problem with your equipment (engine, instrumentation) that you may not realize after years of ROP ops.

Hi, Kenneth:

You also might want to view Module 4, Engine Mixture Theory, in the Beechcraft Essential Systems and Techniques course ("BPPP BEST"), free in the ABS Online Learning Center on this website. Under TRAINING selected PILOT TRAINING and then open the ABS Online Learning Center.

Will view the information above. I am also going to fly with a BPPP instructor so as to learn how to do it correctly. Thanks.

Martin Pauly has a great video on the topic in an A36, albeit not a turbo. Informative nonetheless.

I would give the folks at Tornado Alley a call. They are very good at support and assisting with correcting problems that may exist. As far as TIT goes, there are many turbocharged engines that can not be run LOP due to TIT reaching red line before the desired LOP mixture is reached, and which do not run smoothly if leaned to a point where you are below red line (doing the "big pull" to get there), but this is not a problem I have seen on the aircraft we maintained that had the Tornado alley turbo normalizing system.
