Ethiopian aircrush

As investigations into the Ethiopian Airlines plane crash continue, investigators hope the black box that was recovered from the wreckage will help uncover the mystery behind the tragedy.
In a separate story, TUKO.co.ke reported that the black box was recovered on Monday, March 11, one day after the plane tumbled out of the skies of Ethiopia and crashed in a ball of fire around Bishoftu.

The aircraft was headed to Nairobi from Addis Ababa but the journey was cut short about 60 kilometers from Addis Ababa, killing all 157 people on board.
The aircraft's black box has been taken for examination and relatives hope data retrieved from it will explain to them why their kin's lives were shattered so tragically.

Black box examination is a complex process and it is mostly carried out in the manufacturer's warehouse.
Some government agencies and airlines also have capacity to conduct the procedure.
Modern airplanes are fitted with this equipment that is tasked with recording almost everything that the plane experiences.

The black box is made up of the Cockpit Voice Recorder (CVR) and Flight Data Recorders (FDR) .
It is engineered with sophisticated technology that allows it to withstand very high pressure and temperatures.
It also has a beacon that fires signals to investigators if it comes in contact with water.
This comes very handy in cases where a plane crashes in the ocean and the wreckage sinks to the bottom.
Black boxes are located at the rear of the plane as this area is presumed to suffer less damage during a crash and thus can keep data safe.
Detectives are set to recover the following information:
Flight Voice Recorder (FVR)
Conversation in cockpit
Investigators will be able to listen in to what the pilots said to each other before and during the crash. The conversation will paint a picture of what the crew saw and how they reacted.
The pilot's voices will also be key in establishing whether they were tired. This can be picked from sounds like yawning.

Alarm
Automatic alerts from various alarms in the cockpit will also be heard. They will reveal what on board computers were informing the pilots and also lead to establishing if the crew responded appropriately.
Engine power
Though the CVR captures audio from the cockpit and part of the cabin, it also picks sound from the engines.
By listening to the engines, investigators will be able to know whether they were running normally.
They will also be able to establish if the engines were producing enough thrust to throttle the plane.
Flight Data Recorder (FDR)
The data recorder captures information generated from hundreds of sensors and stores it on an electronic chip.
After recovery, this information can be downloaded on a computer then fed to a flight simulator to recreate the flight.
Inside the simulator, investigators will hear and also experience everything that played in the ill fated fight.
