EFFECT OF VISUAL INFORMATION ON THE MANUAL APPROACH AND LANDING.

A pre-experimental theoretical analysis has been performed in terms of the optimal control model. This pilot-aircraft model analysis resulted in approach performance predictions which could be compared with the experimental results of a moving base simulator program. The results illustrate that the model provides a meaningful description of the visual (scene) perception process involved in the complex (multivariable, time varying) manual approach task with a useful predictive capability.
