Typically, designers responsible for safety-critical elements of aviation — e.g., airframe structures, engines, flight decks, instrumentation, and aircraft flight path automation — must refer to their company’s formal design philosophy and adhere strictly to its current principles and rules.
This article cites, as an explanatory example, a design philosophy likely to be familiar to most aviation professionals: one geared to airframe designers who work for aircraft manufacturers. A technical paper by a Boeing subject matter expert — published in 2005 by the American Institute of Aeronautics and Astronautics (AIAA) — contains insights into how airframe designers work within a clearly established philosophy and well-defined criteria, while considering emerging technology and recognising newly evolving critical design parameters (see Reference).
This overview contains a definition, conceptual scope, and basic elements (examples) that cover how the design philosophy guides or influences professional decisions and practices, in this case, by teams of aeronautical engineers.
