What information is held in the black box of a plane?

Black boxes will help to reveal what triggered an accident, and anything that went wrong. It records information about the plane during its flight, and is built to withstand any damage from crashes or explosions, fire or water.

In really basic terms, it’s the plane’s recording device. It’s placed in an aircraft with the primary purpose of facilitating an investigation should an accident or incident take place. It will record data, as well as things such as a cockpit voice recorder for pilot exchanges and cockpit sounds. It will also pick up engine sounds.

The type of data a black box will track includes altitude, airspeed, flight heading, vertical acceleration, autopilot status and pitch. All of this can help to work out what went wrong, in cases such as the Air India flight.

The cause of the crash remains unclear. However, because the pilot made a mayday call ahead of impact, it suggests they did know something was wrong. According to reports, in can take up to two weeks for data from a black box to be fully analysed.

Speaking to GB News, aviation expert and former pilot Emma Henderson explained how vital the black box will be to the Air India investigation. “Aviation always learns from these terrible tragedies, and the way we learn is to find out that information which is stored in the black box,” she explained.

“The cockpit voice recorder, all of that is stored there and will be extracted. It’s literally like putting a jigsaw puzzle together, so all the pieces will be placed together so that we can see a full picture of what happened between the moment that aircraft took off and the moment it crashed into the ground.”
