Why Do We Call Flight Data Recorders As Black Boxes?

Black Box is also a date recorder, it is like a hard disk, which keeps recording the new data while erasing old one.

Every air craft will have more than one data recorder, one for cockpit and other for recording various sensors.

David Warren of Aeronautical Research Laboratories in Melbourne is credited with the invention of the black box in 1953.

Initially it was black in colour, since it is hard to find in charred remains later started painting it bright orange.

It records actual flight condition including altitude air speed, heading, vertical acceleration and aircraft pitch.

The hard disk is enclosed in a protected box, which prevents damage from impact, fire, water and even accidents.

In 1960, Australia become the first country to make flight records mandatory in all the aircrafts.

The term "black box" was a World War II British phrase, originating with the development of radio and electronic navigations.
