IPad mini on a Flight Outfitters kneeboard. iPhone is backup. (Occasionally dust off paper charts and carry them ‘just in case’ for ‘big’ trips.)
I love AvPlan. (I have not tried OzRunways but hear very good reports about it too.)
(Where do you mount/fit/stow the full size iPad Kaz? I’ve always found them to be ‘in the way of something’.)
