I wonder if it's one of those new TIO-540'd Airvans that the company thinks should be ran at 80% power for cruise.
So what's the problem with that?
You're talking what, 256 hp from a 540 cubic inch engine, hardly pushing the limits.
As long as 80% is operating within the manufacturers limits and not a company wet dream then what's the problem.
"Normal Power" in the Piper Aztec used to be 80% also.
