I'm a GA Pilot and I've wondered
How things like this are feasible.
One aircraft system I use has wifi and bluetooth capability for navigation as well as entertainment purposes. The wifi can be used for a specialist iPad app (called an Electronic Flight Bag/EFB and there are a few products there that do this job) talks to the plane's systems and does "things". I'm guessing/presuming that security is not much of a factor in the design consideration as opposed to ease of use for a not-so tech-savvy pilot just wanting it to "work".
I've also thought that the risk of someone being within wifi range to do nasties whilst the aircraft is in use (ie flying) is extremely low.
Not to mentoin if it _does_ go horribly wrong I can press the red button which disables all the electronic bizzo and fly by looking out the window and looking at my paper maps.
Few things to think about really.
