Ahmedabad accident: What questions will be answered from the ‘black box’ of the crashed aircraft?

The ‘Black Box’ is a set made of the voice recorder (CVR) and a flight data recorder (FDR) in the cockpit of the aircraft.

These include a complete conversation between pilots and air traffic control (ATC). Along with this, it also records flight data parameters like the height, direction and air of the aircraft.

All this information is necessary for investigators to find out when, how and why the aircraft crashed.
