How Unusuality and Reality Intersect in Flight Safety: A Simple Metric for Determining Major Hazards to Commercial Flight Operations from the Unremarkable Accumulation of Minor Unfavorable Elements and a Recommended Operations Adjustment Procedure to Avoid Mishap Occurrence

Abstract: The cascading collection of seemingly minor unfavorable elements during a particular commercial flight can often arouse little notice because there may be no collective safety measuring system or metric to assemble disparate elements. However, just as the story of “the straw that breaks the camel’s back[1]” informs us, flight crew members facing unusual accumulationsContinue reading “How Unusuality and Reality Intersect in Flight Safety: A Simple Metric for Determining Major Hazards to Commercial Flight Operations from the Unremarkable Accumulation of Minor Unfavorable Elements and a Recommended Operations Adjustment Procedure to Avoid Mishap Occurrence”

Qantas Weight and Balance: Don’t Scrape Your Tail, Instead Hold Your Nose Steady

The below cited flight safety story contains a reference to an ATSB report, about which I have a comment. The story alleges that the report cites an incorrect weight and balance calculation as the problem. They say, “This meant that the captain had to apply a significant amount of back pressure [to the yoke] atContinue reading “Qantas Weight and Balance: Don’t Scrape Your Tail, Instead Hold Your Nose Steady”
