As usual, Margaret Heffernan makes a lot of very good sense.
(I believe always keeping a very open mind to be rather wise.)
I've been flying VFR GA with someone on PPRuNe for more than 30 years. I check just about everything that person does and have never been unprepared to question anything that I was doubtful or unhappy with. I suppose that's now known as good CRM.
The properly (IO520) engine monitored aircraft with Gami Injectors runs LOP in the cruise. I'm happy about that because it is logical to do so.
