Airspeed of SR20

try and get some time, when you can read the link that Alex gave you. Gordon nicely made the graph that Alex is using. I and many other pilots have that graph laminated and sitting in our planes. It allows you to run the engine both LOP and ROP in the safe areas. Thus as alluded, running an engine at 75% power and ROP is bad for the engine.

read the link and ask questions. This place is full of knowledge.
