A STUDY TO DETERMINE HOW WELL RATE CAN BE DISCRIMINATED AND CONTROLLED

Abstract

The Army-Navy Instrumentation Program has spot lighted the need for more informat the judgment and control of rates. The embryo helicopter pilot must learn to judge and control several rates of movement before he is able to ac complish the one task of hovering. Little is known of how well rates can be judged and controlled when encoding rate through the use of some symbol or index. Assuming they are judged and controlled within acceptable limits, how should this information be encoded. Sixteen flight-naive and eight flight- experienced people were used as subjects. They were presented two symbols, a line and a circle which either ex panded or contracted. Each subject was given eight trials in each of the four conditions. The analysis of the data revealed that each of the groups tested made smaller final rate and final position errors when using the contracting circle.
