Abstract

In an air traffic control system, an in-line, data cable interface is disclosed for air traffic control signals which provides data access for use by an external computer system while preventing the disruption of the existing air traffic control signals. The interface provides non-intrusive data access even when the conductors of the data cable interface are short circuited. An external computer system has an associated software program capable of compiling received signals from the in-line data cable interface together with signals from other data sources and displaying the signals in, upon instructions of the user, hexadecimal form, polar graphical form or table form or recording the data onto computer or floppy disk. The air traffic control data is compared with data from another source such as a noise detector to monitor aircraft noise. The system provides a step-by-step method of testing and eventually integrating software and hardware into the existing air traffic control system without disrupting ongoing operations.
