In part 3 of my 12th anniversary series "Imagining the Impossible," I describe in detail how to take over the 777 flight control system from the passenger cabin
Hey Trip, sorry for the slow response, I was traveling. I would say that taking over the flight controls would have to come after communications were cut, and before the SDU was hacked. My guess is that the plane was diverted and the plane was depressurized, then the hijackers took control of the cockpit, repressurized the plane, and started feeding spoofed location velocity data into the SDU via the ARINC 629 bus.
Thank you for finally putting this piece together. So how would this fit into the data bus timeline? How does the restart of the SDU figure into this?
