Ok, so I have had ~43 VFR hours flying with my iPad2 (iOS 5.x) with the GNS 5870 to provide GPS information. I have also added a non-glare film to the display. At the very least, the surface is much more "slippery" and those pesky fingerprints are a thing of the past.I use the iPro Aviator knee board. I had made a board from an old aluminium knee board, but it is difficult to write clearences on top of the 'Pad.
On the software-navigation-side, I am using Air Nav Pro 4.x, ICAO Map for Germany (home is now EDFE, was EDMA), the Kagi supplied AIP Approach Charts for Germany. Other Apps include Fore Flight Checklist Lite, AeroWeather, WX Wind Charts, and Sporty's E6B for the Pre-Flight. Flight Route Planning is done over FL95.de (Sorry, only in German, but the functions this web site has *for free* simply are impressive!!) I have tried GoVFR, but I find FL95.de still better for my flights in Germany.
Up until now, the Air Nav froze once at an not critical part of the flight and once it did not get the signal from the GPS unit, but that could have been my fault. After about 10 minutes, I could copple the units again. The iPad has always worked. I have been flying mostly in C152s and 172s and since recently, in a AA-5. The iPad has always been readable in every lighting situation.
The situation awareness is simply astounding, especially around EDDF/EDFE where the airspace can be complicated and the clouds like to hang low. What I really appreciate about the moving map is that the traffic circuits come up automatically; it really makes flying to an unknown field much easier. Combine the iPad with a Garmin (add your favourite model), you have an unbeatable combination.
I do not use the Checklist App in flight. For start-up, taxiing, and before departure, yes, but I find it still to unwieldly to switch between apps especially in the pattern when my eyes need to be looking outside and not concentrating on app switching. Paper checklists are aways ready to grab.
My battery life seems to be about 4-4.5 hours. Like fuel, I do not like to run her dry, but after a 4 hour flight I have ~18% battery. I have the WLAN turned off, Bluetooth on (GPS unit) and brightness at max. On longer legs, I could turn the unit off, but Air Nav sometimes has issues with finding its location again. I think it would be better to have a external power supply, either a cable from the cigarrette lighter or an extender battery.
Can I do without using an iPad? Yes. Do I want to? No.
