Preliminary Guide for the Assessment of Fly-By-Wire High Reliabilities.
Abstract
The problem of demonstrating and verifying the flight safety reliability of a helicopter Fly-By-Wire (FBW) system through laboratory and/or flight tests is investigated. The objective is to provide preliminary recommendations as to the method of demonstrating the flight safety reliability. Acceptance test methods based upon classical parametric statistics, classical nonparametric statistics, and Bayesian statistics are investigated. The following topics are discussed: component reliability predictions; nonparametric examples; confidence; parmaetric and nonparametric sequential tests; parametric examples; exponential and normal distributions; failure terminated and time terminated tests; Bayes' Theorem; Bayesian discrete reliability example; and various prior reliability distributions.
