1. A sketch of the obstruction surfaces defined in FAR part 77 is shown in Figure 1 The obstruction surfaces are to be defined for approaches to a 6,000-ft runway designed for use by transport aircraft for non-precision-instrument operations with visibility minima greater than 0.75 mi. The elevation of the runway is 350 ft AMSL. Determine the coordinates of points A, B, C, D, E, F, and G A D C Figure 1: Schematic diagram of FAR part 77 surfaces LJ
