ABSTRACT
This chapter applies the basic outline of human information processing to the aviation context. Visual illusions in flying are frequently associated with inappropriate experience or expectation on the part of the pilot. Mental models are usually accurate and bear a good relationship with the real world, but sometimes the data provided by the sensory systems can lead to a model being made which is inaccurate. There are a number of ways in which the pilot can suffer from illusions of orientation. The only solution to all forms of spatial disorientation is for the pilot to trust the most reliable form of information available to him, and this will almost invariably be his instruments rather than his own sensations. Any pilot exercising a skill, such as lowering the undercarriage would make the decision to do so, and then monitor his own behaviour in order to ensure that the correct skill was exercised.
