No Power

[andyjohnston.net 617]

I have an issue which is affecting all my piston driver aircraft, and I'm wondering if others are experiencing the same or can offer a solution.  Once they get above a certain altitude, usually about 10,000 feet, the power drops off.  I can see the manifold pressure is way down, even though I have the throttle levers maxed.  I have no (to my knowledge) items set in the options which would cause this.  It's really hard to, for example, cross the mountains when then plane can't go very high.

I would check that something didn't get mysteriously changed under Assistance Options, like AutoMixture, etc.

Ah, thank you for the suggestion.  Automixture had changed "on its own" and I reset it.  I was then able to power up to 25,000 feet.

 

Thx again.  🙂
