What is the size of a black box on an airplane?

A black box, typically consisting of two components—a flight data recorder and a cockpit voice recorder—varies in size but is generally about the size of a large shoebox, measuring approximately 12 inches (30 cm) in length, 6 inches (15 cm) in width, and 8 inches (20 cm) in height. Despite its compact size, it is designed to be extremely durable and capable of withstanding extreme conditions, such as high impact and intense heat, to ensure the preservation of vital flight data.
