Good surprise during the ARC transatlantic 2011.
After transferring photos from my device to my iPad, for an unknown reason the storage memory was full. I had 9GB free and I only transferred the contents of a 2GB SD-Card. Mystery !
Anyway, after two or three system messages warning me of the upcoming saturation, iOS 5 has simply deleted all my Navionics map used by iNavX !
When asked by e-mail, Rich Ray confirmed the fact possible :
"This is an unfortunate change in iOS5, the iOS will and can clear any apps downloaded data without notice if another app needs more space.. iOS doesn't give any notification to the app if this happens".
Olivier Bouyssou told me it was possible for developers to store application data in a folder reserved unerasable, but that this was rarely allowed by Apple. This was a big problem because no one knew how iOS selected which apps it cleared from.
Yachtmen my friends, be prudent : if you do not want to lose your charting during the cruise, away from any network allowing you to download them again, monitor the available space of your iPad and iPhone.
Francis,
A fix if it's buggy. For me, This is a "normal" way of working.
Another example :
I have an app on Ipad : save2Pdf. With ios4, you could generate a pdf of any Ipad app, nice. Updating with iOS5, more possible.
Contact with app support ( Paid app with a company behind it with employees). They explained to me that Apple blocked this function without notice. Too bad for me but especially too bad for this society which is very very bad, their business undermined without notice by Apple.
CQFD

Francis, Bad News, but are you sure it wasn't a one-time bug on your iPad ? As you say, You had more than enough space in memory, so the iOS didn't need to delete data.
Moreover, I am not a computer scientist, but I can't imagine that iOS is hard-deleting data like that. It's normal for the system to make room in RAM for other apps, but deleting data seems incredible to me. This would mean that the iPad would regularly delete other large files such as music, photos or videos, which never happens, while most users have an iPad that is much more "full" than yours.
However, it is a proven fact. It has been the subject of several relationships from American developers. For example :

Let's hope that Apple will make a correction to this way of working soon. I don't have any information on that.
Bonjour,
I understand the craze for using an iPad on your boat, however, from the point of view of computer scientist that I am, I find this choice a bit risky for several reasons :
– Product youth : This will be resolved over time.
– No operating system proficiency.
It is important to understand that an iPad works as Apple wants it to and that we install what Apple allows us to install.
Don't make a mistake, it's by no means primary anti-Apple (I'm equipped with all kinds of ibidulles), it's just an observation.
It's not because Apple easily gives Michu the ability to have her cards on her iPad, that we must forget a fundamental reflection :
– Do I master my tool ?
The answer is no, Apple has the keys.
For my own, an iPad will never be able to replace an embedded system dedicated to instruments, unless you dedicate the iPad to the map and no longer do iOS updates, or crossing your fingers every time.

Gulps …

So I'm going to leave my Camera Kit Connection at home, my photos on my iPhone, and my maps on my iPad … And to be continued in the next episode …
Welcome back among the Earthlings Francis !…!
