Human factors engineers and specialists work with varying sizes of humans in a variety of design situations. The Human Factors Design Guide are specifically developed to assist these professionals in their work. There is a long-standing discussion of whether the working environment should be designed to accommodate human characteristics and functions, or whether the human should be selected and trained to operate efficiently in a pre-set operating environment or condition. Take a stand for either of these views and defend your reasoning. Select a particular aviation or aerospace example to illustrate your case.
