Abstract
A three-dimensional grid is created by a series of panels arranged in a s-circle about a seated subject. The panels are configured or otherwise arranged to allow the seated subject full range of reach in all directions. The subject may be seated or standing and is placed a distance from the panels. The panels include a plurality of rods which slideably project through the panels in the direction of the seated subject. To determine reach, the subject reaches toward the rods and pushes them with either hand as far away from him/her as possible. Measurements may then be taken from the end of each rod that has been moved. Similarly situated panels, including visual indicia, may be used to evaluate field of view.
Claims8
An aircrew field of view measurement device for evaluating a subject's crew person rearward vision related to equipment located within actual cockpit structures each having known dimensions and each having a rearward structure and an aircraft cockpit located therein, said measurement device comprising:
- a plurality of vertical panels each located a predetermined distance behind said subject crew person and arranged in a semi-circle, the predetermined distances between said subject and said panels approximating the distances between said subject and said equipment within said actual cockpit structures;
- and
- a plurality of indicia on said panels, said indicia being arranged along a horizontal line across each of said panels and being sighted by said subject crew person turning his/her head so that said indicia is within said subject's crew person rearward vision.
The method of measuring aircraew reach capability relative to a fixed point, comprising the steps of:
- placing a plurality of vertically standing panels arranged in a semi-circle in front of a subject;
- placing a plurality of horizontally extending rods through said panels in the direction of said subject to points within an extent of said subject's reach which involves little difficulty to achieve;
- pushing the ends of said rods toward said panels by said subject which involves the full extent of said subject's reach to achieve;
- and
- measuring the distance the ends of said rods extend from said fixed point.
