To maximize the resolution of the vortex mapping in the most efficient manner, the matrix was based on 1/8 of an FlA-18 wingspan, or just under 5 feet. ap the vortex, a grid of test points, or test matrix, was created. Because flight test time was limited, the number of matrix points had to be kept to a minimum without sacrificing the resolution of the vortex mapping. In addition, the guidance (needle)display used by the trailing pilot to fly each test point was limited to 60 target files. Designed within these boundaries, the test matrix was based on 1/8 of an FlA.18 wingspan( F/A-18=37.5 ft), or about 4.7 it a grid of equally-spaced points in the Y-and Z- axis was then set up using this parameter.
