BLACK BOX IN AIRCRAFT

The Black Box

A black box in aircraft

Although they are called "black boxes," aviation recorders
are actually painted bright orange, are a group of data
collection devices mounted on the tail of an aircraft.

Dr. David Warren, a Australian aviation scientist
proposed a flight recording device and by 1958 he had

produced a prototype “ARL Flight Memory Unit”

  

Data from both the CVR and FDR is stored on stacked

memory boards inside the crash-survivable memory unit

(CSMU).

The black box is powered by one of two power generators

that draw their power from the plane's engines. One

generator is a 28-volt DC power source, and the other is a

115-volt, 400-hertz (Hz) AC power source
