Extract

In considering reliability, it is logical to look at sources of uncertainty, variability and inaccuracy. British Civil Airworthiness Requirements - Section D defines the factor of safety in terms of several sources of unreliability, as follows:

uncertainties in loads,

inaccuracies in structural analysis,

variability in the strength of materials.

Type
The use of reliability techniques to improve structural efficiency
