Proper way to lean a C337?

Recommended Posts

Hopefully this will help with my other aircraft that have both propeller and mixture controls, but I am constantly getting a "loss of power due to improper leaning" message when I fly my Carenado C337.

 

The easiest solution would be to press CTRL-X and let FSX resolve it, but I would really like to learn how to do it myself.

 

Any tutorials, guidance, etc. would be greatly appreciated.

 

Thanks,

Ernie

It is usually ineffective to lean below about 3,000'. But after climbing through 3,000', look around the  panel (right side) and find the EGT (Exhaust Gas Temperature) gauge. Begin leaning the mixture and watch the gauge. The temperature will begin to increase until it reaches a peak temp and begins to drop off. You should also hear a slight drop in the power as it reaches its peak. When you reach peak bring the mixture forward, back to richer, until the temp falls to about 40 degrees below peak or usually two increments.

 

This technique is known as flying "lean of peak". Some pilot/owners today advocate flying rich of peak to maintain lower temps and less fuel use, but that is still a bit controversial.

 

Oh, and you might want to just turn off that message. It can be rather bothersome once you have perfected the technique. Should work fine on most of your other piston aircraft.

 

Good luck with your 337.

That is called running rich of peak...

 

Lean of peak means you continue leaning (mixture aft) below (past) peak.

Oops! Thanks for the correction, Ozzie. Of course you are correct. I said it totally backwards.

 

I should have proof read a bit more carefully.

No problem sir.  Just wanted to make sure we "all on the same page".   :P

Thanks.. I'll give it a try this evening..

 

I usually turn off the flying tips, but find them somewhat helpful when I trying to learn a new aircraft.  Once I've got some hours off they go.
