Need and justification for automatic, in-flight, thorough built-in test capabilities in advanced avionics systems is discussed and the need for a systems design approach is stressed. The role of an airborne digital computer for sequencing, conducting and evaluating the built-in test and the great flexibility of this computer, its characteristics, program and interface are developed and applicable test methods and design techniques are illustrated by typical examples. Short comings of methods used to continuously monitor all functions in flight and alternate builtin test methods are covered; evaluation logic and time-sharing of tests are discussed.
