Alternative Name(s): 'Black Box' Flight Recorder
Part of the prototype first airborne Aeronautical Research Laboratories (ARL) Flight Memory recorder unit invented by Dr David Warren. The wire recording unit was connected to this crash signal monitor in a separate impact and fire-proof box mounted in the tail of the aircraft. The unit was first flight tested in Fokker Friendship VH-CAV flying from Essendon airport, Melbourne on 23 March 1962.

This invention subsequently became colloquially known as the 'black box flight recorder'.
