Vertical launch includes all facilities and land area directly related to vertical launch operations, inclusive of launch pads 39A, 39B and 41. It also includes immediately adjacent launch support facilities required to be operational at the time of launch. Quantity Distance (QD) arcs, launch hazard impact limit lines, other safety setbacks, and exposure limits are considered restrictions on the use of land adjacent to the Vertical Launch area. Land within these QD arcs is not designated part of the vertical launch land use.
