Hello!
...did you use the TGL 36 doc.
We did start based on this one about two years ago. Using "real" EFBs on one aircraft that is large enough for them. After completing the trial period successfully and gaining approval, we derived our own procedures for the iPad from it and got them approved as well. Pending completion of the trial period, but this has been completely uneventful so far. Today, I think the detour via the TGL 36 should no longer be necessary. There are already so many approvals for iPad based electronic charts that the authorities can hardly refuse them any longer.
