Abstract:
A collision avoidance system for a warning aircraft includes a transmitter and receiver for interrogating the transponder of a warned aircraft. A computer to be installed in the warning aircraft is programmed with the distances or rates of closure at which the warning aircraft and the warned aircraft constitute traffic for one another. When the computer has determined that the warning aircraft and a warned aircraft constitute traffic for one another, a warning system broadcast an appropriate vocal warning.
