OK, here's a question I have not been able to find an answer to anywhere.
What is the effect of DA on static RPM? I know drag decreases as altitude increases and at least partially offset the loss of horsepower. But still, when you get to 7000-10,000ft density altitudes, what happens?
My new digital tach shows my engine is not quite making static RPM (about 75rpm low). But DA today was 7500ft at the runup pad.
