We're moving everything to the iPad and I've done my last paper Jepp update a month ago!
I would like a plot chart on the iPad that you can draw on.

Change to iPad Pro ...
We changed cockpit iPads to Pro recently and now with Apple Pencil we can draw on almost any document with the right program (only our documents in Apples own Pages and Numbers have to be converted to MS Office documents, because Apple support for that technology is not sufficient in their own office suite ... what the hack is going on at Apple development?).
A pilot fellow took my plotting charts to his wife's multimedia company big scanner and made a PDF of it. On the iPad Pro I can now draw on it like on any paper and keep the paper for backup in the case. I guess it is just a matter of time until the charts are available officially as PDF.
