  • Such a device is completely independent of aircraft systems, contains no flammable batteries(!) and cannot really pose any additional risk to an aircraft to which it is fitted.Caveats: It stops working when the aircraft stops moving, and there is a limit to how much power one can draw in this parasitic way.As an extension to the basic concept, one could add a wide-angle camera that takes snapshots
