AVIP is predicated on the basic understanding of how the equipment will be maintained, the environments it will experience, the property of the materials, and the failure mechanisms and fatigue methodologies inherent to the design. This process establishes the design allowable, manufacturing and process controls for the equipment, and demonstration to meet functional and life performance requirements.This paper provides an overview of the Avionics Integrity Program. It emphasizes fundamental cause and effect aspects of the avionics design. Engineers and managers will benefit from understanding some of the major activities presented in this paper. Returning to good old basic engineering is the first and the most important principle for all of us to follow in acquiring a combat capable, cost effective weapon system.
