Hijacking airplanes with an Android phone
I used to make avionics for a living and I don't even understand what this man is talking about. (I don't think he does too) That seems to be just an ACARS sniffer.ACARS and ADS-b has nothing do to with aircraft control systems. You don't need an android app to intercept satellite communication and even if you 'root' the ACARS computer, it is not connected to the systems that could control the airplane.Also: to pass DO-254 at level A you must have physical switches for flight/computer functionality, that said, no software can engage autopilot or change AP behavior, you need physical switches to do that. They are NOT similar to keyboard buttons, those switches actually interfere at the hardware level.
