There is a strong link between the Airworthiness of a particular aircraft operation and the original assumptions regarding Configuration,

You must illustrate your answer with at least one example taken from either civil or military aviation. All reports must be presented on a standard A4 page, with lines double-spaced, in a 12-point font such as Times New Roman, Courier or Palatino. Sensible margins, e.g., 2.54cm should be used. Wherever possible, you should use appropriate graphs, tables, diagrams and figures to augment the text.
