Won't work for two reasons:
1) It is not an iPhone-based training package. If I know which one you are talking about, it is Windows-only and there is not an option even for Mac OS
2) Apple restricts the software you can put on the iPhones via the app store. Until Boeing puts something in the app store (won't happen), there will be no way to get the software onto the phone, even if it were compatible with the iPhone (see #1).
Now, there are finally a few ways to get stuff on an iPhone in an enterprise envrionment, so if your iPhones are provided by PIA and are managed by them, they may be able to "push" apps to your iPhone, so #2 may not necessarily be true.
In the end, though, it all boils down to point #1.
The above post is my opinion. Don't like it? Don't read it.
