I plan on buying one for exactly that use-case. I have a mini 5 that's showing its age and doesn't have enough storage (downloading flying charts takes up a surprising amount of space) and I didn't want to upgrade to the mini 6 considering how long in the tooth it was getting. The mini 7 isn't some massive improvement, but it's improvement enough in a very good niche for flying.

Edit: For the non-pilots reading this, it's also worth noting that the most popular flying app by far for general aviation at least, ForeFlight, is iOS only. So your choices are generally small iPad or big iPad, and a lot of people don't like big iPad in a small airplane cockpit.
