AIT Recorders has developed a digital air-traffic-control (ATC) data-recording system, which it claims can simultaneously record all radar, voice and environmental data entering an ATC centre, using digital compression techniques. The UK company's Comfile 2000 Digital Recorder uses DAT cassettes as the storage medium, along with a 1Gb hard disk for temporary storage, allowing instant replay of recently recorded information.
