So my suggestion on NOT using the ipad as a PFD and/or primary moving map may be changing a bit. I got this email this AM from the founder if iHUD for the iphone/ipad. I had asked him a while back (actually before the iphone 4) about utilizing one of the micr AHRS devices that are out and about for connection to an iphone to provide a true back-up (or primary) attitude instrument for flight applications.

Hi Emmet,
It has been a while. But now I have good news. We have worked hard to get iHUD Remote done, which is the real AHRS thing. I know it is not as expected the iHUD Pro, but probably much more designed for the pilot.
Please check iHUD Remote which is available on the App Store

Hope you are doing fine!
Best regards,

The AHRS is the real development. Evidently the internal gyros in the ipad 2/Iphone 4 have been notoriously difficult in eliminating drift/instability due to vibration and other issues encountered in an actual plane. This little guy is a true remote AHRS with air data capability.
What makes this so compelling now is the rate of development and refinement of flight software going on for the ipad. It's so "upgradable" that probably it will become a truly competitive choice as use for a PFD/Moving map to purpose-built aviation tech. It's got to have some of the hardware mfg's a little nervous.

Note that it works with several applications including Wing-X, iHud, and some others. Some providing now true synthetic vision.
Pretty cool!!
