CA,
How would the 13 inch model be more effective?
My airline:
The maintenance release document must be paper. If international the master flight plan and plotting chart must be paper.
Other than that, the IPad and ACARS suffices. I don’t see ACARS paper going away for quite some time.
We have MDM on our iPads. We use Content for our manuals etc. Jepp FD pro for backup manuals. Another app for flight by flight backup charts to FD Pro. App updates are almost transparent and seemless. Our inflight internet access is very good and works 95% of the time (North America), turning the system off then on seems to fix the other times.
The biggest EFB problem I have noted is app updates and their improved features are communicated poorly to our pilot group. I find many pilots not taking advantage of what the iPad and flight related apps have to offer.
