Need to look up some quick performance data during your next flight? Do a quick and dirty Weight & Balance? It's all at your fingertips.

The Diamond DA40 is the latest edition of POH data applications for the Apple iPhone/iPod touch. The data for this application was taken from a June, 2008 POH.

Various performance data have been entered into this program such as weight and balance, take off distance, landing distance, climb performance, and climb performance. For the first time ever, a checklist option has been added for the most common

As always, when in doubt or error, you should always refer to the official documentation supplied with your aircraft.

"I personally use several of the PunkStar Studio iPhone/iPod applications. Some, like the Cold Air Calculator, are incredibly useful for even the most advanced pilot, while others, like the Hold Pattern Calculator, are perfect for demonstrations with my students (who are thrilled when they see it for the first time). I'm a loyal customer/user of several of the PunkStar Studio apps (even non-aviation related) and look forward to their future releases. I highly recommend their products to all aviators, from the professional airline pilot and flight instructor to the casual pilot."
