YOUNG CHRONICLE November 28th, 2014 An Aircraft’s Flight Recorder A flight recorder (or aircraft's black box) is an electronic recording device placed in an aircraft for the purpose of facilitating the investigation of aviation accidents and incidents. Any type of aircraft in any condition of flight can be viewed in terms of its input parameters (e.g. conversations between the pilots, control instructions etc.) and output parameters (e.g. flight sensors). The exact working of the Black Box isnʼt revealed, however the input and out put parameters can be known, especially during investigations. So now we know why a Black Box is has been given the name. Thatʼs because no one knows the internal workings of a black box. The flight data recorder (FDR) is an independent device that preserves the recent history of the flight, through the recording of dozens of parameters, collected several times per second. The cockpit voice recorder (CVR) preserves the recent history of the sounds in the cockpit, including the conversation of the pilots. These two recorders give a testimony, narrating the flight history with accuracy and impartiality, to assist in an investigation. FDR and CVR may be combined in a single unit. The two recorders are required by international regulation to be capable of surviving the conditions likely to be encountered in a severe aircraft accident. For this reason, the Flight recorder is typically specified to withstand an impact of 3400g (gravitational force) and temperatures of over 1,000 °C. So, they should be able to find out what happened to the Malaysian Airlines and the Air Asia Flight. Well, may be. They have found the tail of the Air Asia flight at least. If the Black Box is in the tail, they’ll know what happened. As for Malaysian Airlines, they haven’t found any part yet. This is the New Year Resolution Box.
