Hi guys, trying to figure out what I may be doing wrong here.

I keep losing power or manifold pressure about 10-15 minutes into each flight and end up having to make an emergency landing.

All engine instruments are in the green...not sure what I am doing wrong.
Figured I am mistreating the engine but when I return to the hanger it says its in excellent shape. No fouled plugs etc.
Also not out of fuel.

Any suggestions where I may be going wrong here?

Thanks Jason

Check the weather around you: you might need to use the carb heat!

ah, certainly a good thought. Didn't think I would need it flying in summer weather. Hadn't occurred to me

Yeah, hot and humid weather, or any conditions when there's moisture in the air (such as rain) present a risk of carburettor icing in the Comanche. Take a look at this article and the included chart if you get a few moments Jason, it gives a good summary of the phenomenon: Melting Moments: Understanding Carburettor Icing.

Cheers,
Nick

Yup sounds like carb heat for sure, if in doubt/questionable conditions turn it on is a god rule in the simulator for it.

thanks,
Lewis
