Abstract Two case-studies on uncommon metals whiskers, performed at the Reliability Analysis Laboratory (RAL) of Northrop Grumman Innovation Systems, are presented. The components analyzed are an Oven Controlled Crystal Oscillator (OCXO) and an Electromechanical Relay. Investigative techniques were used to determine the chemical and physical makeup of the metal whiskers and develop an understanding of the underlying effects and mechanisms that caused the conditions conducive to whisker growth.

Safety Metrics

This article details a novel method for the determination of safe flight paths dynamically following an in-flight distress event. The method is based on probabilistic safety metrics which also include the touchdown and evacuation/rescue phases after landing. Two case studies simulating in-flight distress events, one from the west and the other from the east coast are presented using these formulations for a quantitative analysis. It is found that the nearest landing sites are not always the safest ones showing the benefits of the newly developed safety metrics. Finally, the path safety levels are plotted as a function of mission safety probability values using innovative polar plots that provide useful information to pilots.
