During the period 1 June 1978 and 30 April 1979 the AN/SYQ-7(V)2 NAVMACS A+ System was monitored by FRAP under operational conditions in a heavy ship-to-shore traffic environment on deployed platforms. A total of 19 selected platforms participated in the study during which 53,272 hours of operating time was accumulated. A total of 26 equipment failures were reported, which places the observed equipment MTBF at 2049 hours. At the 90% confidence limits, the actual equipment MTBF is not greater than 2827 nor less than 1629 hours. The observed duty cycle for this system (operating hours/calender hours) was 0.556.
