And what happens if it isn't? And how would be this be any worse than no device at all?

  The device recording plane data is presumably connected to important plane systems to record them. Can data/electricity only flow one way? Are you sure?

    Why? for location data all they need is GPS. If you know location you find the black box which has the telemetry data. Is there a reason a location tracker can't be self contained with it's own power supply and no connections to a plane's telemetry feed?

      If you do that, the next time there's a crash like Air France 447, you'll see rending of garments and crappy articles like this (again) saying "Why have a black box when you can just transmit the data?!?!?!" http://en.wikipedia.org/wiki/Air_France_Flight_447#Underwater_search http://en.wikipedia.org/wiki/Air_France_Flight_447#Underwate... > French Bureau d'Enquetes et d'Analyses (BEA) chief Paul-Louis Arslanian said that he was not optimistic about finding them since they might have been under as much as 3,000 m (9,800 ft) of water and the terrain under this portion of the ocean was very rugged. Although France had never recovered a flight recorder from such depths, there was precedent for such an operation. Crashed: June 2009 Black boxes found: May 2011

        Notice that the AF447 had great telemetry reporting its position right before the accident. Searching for things at the sea bottom is simply hard.
