| The experience of users of motion simulators for training has lead to the conclusion that motion is beneficial to transfer of training. However, there is need for data relevant to the question, how much motion should be used. The purpose of the study was to provide data relevant to the specification of motion requirements for ground-based trainers for aircraft pilots. The study investigated three categories of motion: no motion, ... |

J. A. Bynum; W. G. Matheny; J. E. Flexman; R. K. Wilson; LIFE SCIENCES INC HURST TEX
|
| The investigation tested a model which hypothesizes that the critical visual cue for control of a helicopter is the relationship between a fixed internal referent placed on the helicopter windscreen and an external referent placed on the ground plane. To investigate the likelihood that a pilot could maintain vehicular control through detecting changes in the inter-referent distances, both laboratory and field experiments were designed. The laboratory investigation was concerned with ... |

J. R. Thielges; W. G. Matheny; HUMAN RESOURCES RESEARCH ORGANIZATION ALEXANDRIA VA
|
| The visual Discrimination Analysis is a method of examining the cue structure of the helicopter pilot's visual environment. It is hypothesized that the critical cue is the relationship between two referents--a fixed internal referent placed on the helicopter windscreen and an external referent located on the ground plane. Cue value is analyzed through the geometric relationships of these referents for the six degrees-of-freedom: pitch, roll, yaw, altitude, range, and latitude. ... |

|
| The problem of human factors field evaluation within the Navy was examined for the purpose of formulating recommendations for improved evaluative methods and techniques. It was concluded that human factors evaluation does not receive emphasis or support comparable to that given equipment evaluation or commensurate with the importance of the human operator to the successful functioning of the system. Much more definitive and timely information must be provided the human ... |

Experiment One incorporated the coefficient changes in the longitudinal mode; Experiment Two in the lateral mode; and Experiment Three in the combined longitudinal and lateral modes. On the basis of study results, it was concluded that feasibility of these reduced ... |
