What is a tri-service inquiry?
It is a kind of an inquiry, in which the representatives of three armed forces - Army, Navy and Air Force--will be included..
Normally a chopper crash inquiry is done by the Air Force officials only, but since the list of deceased includes the CDS, a tri-service inquiry has been ordered.
A black box is a device (Similar to a hard disk) that is installed in aircraft to help investigators in case of unfortunate accidents.
Why is it called Black Box?
The term “black box” was first used by the British during World War Two and referred to the secret development of radar and electronic navigational aids in British aircraft. These secretive devices were housed in non-reflective black boxes.
While crashes can happen anywhere both on land and over seas, the flight recorder is designed in a way that it can be recovered from underwater locations as well. The device sends out a signal on contact with saltwater that can be picked up within a radius of about two kilometres. The device can withstand water pressure found in depths of up to 6,000 meters.
Double wrapped in a corrosion-resistant stainless-steel container with high-temperature insulation, the black box is designed to withstand the harshest crashes -- on the land and seas.
