Abstract : The objective of the investigation was to determine if it is feasible to significantly improve the recovery time of the RBDE-4 system after it has gone through an interruption of primary power. Tests made on two RBDE-4 systems showed they were left inoperable for approximately 2.5 minutes, even though the interruption of primary power lasted only a few seconds. Further tests and investigations provided a quick recovery modification to the RBDE-4 scan converter. This modification returns the RBDE-4 system to normal approximately 120 seconds earlier than without the modification. Since primary power failures often occur at a time when air traffic controllers most need the radar information, a return to normal 120 seconds earlier is considered a significant improvement in recovery time.
