The PROAV Cable Warning System CWS is a commercially available system designed to detect the electromagnetic field generated by current-carrying wires operating at frequencies of either 50 or 60 Hz. The system is designed to alert helicopter crewmen to the presence of these wires to help prevent wire strike mishaps. As directed by the U.S. Army Aviation and Troop Command, the Aviation Applied Technology Directorate performed an aircraft integration assessment of the CWS followed by field evaluations in Germany and Korea. These field evaluations were not operational tests, since no standard or specification exists by which to judge this system. The CWS was successfully integrated on the AH-64A, AH-1F, and UH-1H aircraft. During the field evaluations, the CWS was flown a total of 207 hours by 40 different pilots. The conclusions were that the CWS was not consistent in its ability to detect wires and provide sufficient reaction time and that pilot confidence in the capabilities of the CWS was marginal to low. Also, significant aircraft integration issues remain unresolved for several U.S. Army fleet aircraft.
