I have read the RVator article where Vans talks about the condition for the cruise speed test is 8000'DA, max RPM (or best) and ROP for max power at that altitude.
But . . . I can not find where the conditions of "top speed" testing have been stated. So, just where does the normally aspirated airplane make its highest TAS? Is it down low where the engine makes the most power, but the airframe drag is also way higher or some odd place (yet to be found) in between sea level and the specified cruise condition?
