Results are presented of an investigation into reliability characteristics demonstrated by selected avionic equipment over the major portion of their expected service life. It was found that avionics equipment items of various types demonstrate remarkably similar trends of a gradual decline in reliability during prolonged service. The data provide a basis for modification on J.T. Duane's learning curve approach (1964) by extending its applicability to project a reliability profile over an equipment's planned service life. The revised equations are then used to predict changes in equipment reliability and availability, thus providing a capability to more accurately estimate life-cycle support resource requirements and costs.
