Lessons Learned from Utilizing PEMs in a Flight/Safety Critical System

Abstract

In 1997 the Naval Air Systems Command F/A-18 Flight Control Team was tasked with redesigning the Flight Control Computer's processor card. This was mainly due to parts obsolescence. The old processor incorporated mid-SOs technology. The processor card contract was awarded to the current computer manufacturer. Issues raised due to the obsolescence of military rated ceramic microcircuits: Design options limited using only MIL parts or PEMs with full MIL temp rating, Microcircuit Industry market is PEMs, The most common rating for PEMs in the marketplace today is the commercial grade of O deg C to 7O deg C, How to use and quality commercial grade PEMs for a Military Flight Critical System.
