Power Wheel app for iPhone and iPad

As a pilot, you want to treat your engine well. Its one of the most valuable parts of your plane and you want it to last. Weve taken the hard-to-read cruise power setting tables and graphs from your POH and made them usable in a brand new way. Now, you can calculate how much power your engine is producing. At any RPM, any MP, any altitude, and any OAT while you operate rich or lean of peak EGT. And when you know how much power your engine is generating, you know how treat it right.

We use the same calculations the engine manufacturers use, applying the same laws of physics and chemistry to calculate what your engine is really doing. At any power setting you choose. Dont be confused: When you know more about how your engine operates, you can make the proper decisions about how to operate it. Choose a power setting that makes sense to you, and then choose a mixture that is good for you and your engine.

Yes, when operating rich of peak EGT, the factors involved are complex. Thats why weve done the math for you, and put it all into a simple to use form thats quick and easy to use, at your desk or in the cockpit using your iPhone or iPod Touch

Now weve taken the same calculations used in the original Power Wheel and put them into your pocket with your iPhone. In fact, Power Wheel for your iPhone does things the Wheel never could, including automatic calculation of the "standard" temperature for your chosen altitude and the calculation of the density altitude as a bonus.

This new version of Power Wheel now supports all normally-aspirated and turbo-normalized engines, both with controllable-pitch and fixed-pitch propellers.
