APPENDIX B

The next step is to determine the orthonormal distance from the airport to the facility.

The first method is to use Equations B-1 and B-2. A second, graphical method is

illustrated below using Airport 2. Begin by placing the origin in the center of the

runway. Next, draw a line splitting the runway in half lengthwise. This line represents

the x axis. Draw a line from the facility that is perpendicular to and intersects the

x axis, as shown in Figure B-5.
