Airline Flight Testing for Reliability and Maintainability 640607
A major portion of airline flight test activities is devoted to the testing of airplanes after the airplanes have received a periodic overhaul. These tests are essential to confirm that there are no reliability deficiencies which would affect safety. Flight tests can assist in maintaining the general level of reliability insofar as non-safety aspects are concerned but this is a very expensive method of assuring reliability. The cost and the effectiveness of flight test as a method of controlling the general level of reliability are exemplified.
