what colour is a black box?

Question

on an aircraft is the black box black.if not what colour an why is it called black box?

Answer 1

When an airplane crashes, what follows is inevitably a search for the black box, or more accurately the two black boxes, one that records the voice conversations in the cockpit and the other that records data about the flight, such as location, speed, and altitude. The odd thing is that whenever the boxes are recovered and shown on the news, they are not black at all. Rather, they are painted bright orange for visibility at a crash site.


So why are they called black? Black box is a generic term for a piece of electronic equipment on an aircraft. The term originated in air force slang during World War II. The first black boxes were radar bomb "sights." Partridge's Dictionary of R.A.F. Slang (1945) contains the following entry:

Black box or gen box, instrument that enables bomb-aimer to see through clouds or in the dark.
The term was also used by US air forces during the war. Hamann's Air War (1945) defines black box as radar.

Later, the term expanded to include various electronic navigational devices. When the flight recorders started being installed on civilian aircraft in 1958, the name was applied to these devices. The original WWII black boxes were literally colored black and many pieces of avionics equipment still come in black housings, but the term is applied to all of them regardless of color.

Answer 2

There are actually two "black boxes". One is the cockpit voice recorder and the other is the flight data recorder. They are orange with a diagonal stripe on them and are equipped with an underwater locator beacon. I was an avionics technician for six years in the Air Force. Also, check my source.
