The effect of visual information on the manual approach and landing

The visual scene is an important source of information for the manual approach and landing task. This study deals with the effect of this information in combination with basic display information on the manual approach performance. In this context, a pre-experimental theoretical analysis has been performed in terms of the optimal control model....

Thresholds for the visual perception of position deviations and motion

During a visual approach to landing a pilot uses cues in the visual scene for the control of aircraft attitude and flight path. The accuracy with which some relevant display elements can "be set at a desired, nominal, position was determined in an experiment via the phychophysical "method of adjustment". Furthermore relevant literature with...

Visual scene perception process involved in the manual approach

The outside scene is often an important soiirce of information for manual control tasks. In the context of aircraft control the most important example is the visual approach scene. This study deals with modelling the visual scene perception process on the basis of linear perspective geometry and the relative motion cues and investigates its...
