The growing body of technology relative to maintenance monitoring provides substantial evidence that on-condition maintenance will be a reality in the foreseeable future. The Military Airlift Command's MADAR (Malfunction Detection, Analysis, and Recording) System is emerging as the “missing link” which has heretofore retarded progress toward attainment of this increasingly-important goal. The key issue is real time response. Monitoring-system reliability, accuracy, and repeatibility are all of little consequence if the system output is not timely enough to assist the maintenance function. Recent use of communications links by some airlines to transmit recorded data to a centrally-based computer has reduced the time span between data generation and its availability for use. Nevertheless, the response time is still estimated to be somewhere between 5 and 24 hr.
