Defining the terrain and obstacle profile settings

The terrain and obstacle profile element provides a view of the runway and approach surfaces as well as any obstructions and terrain that protrude through them. The appearance of this element can vary based on your organization's requirements and the specification used, FAA or ICAO. The properties for the element are divided into the following groups:

• General—Properties related to the element height and resetting the properties to the default values
• Scale—Properties related to the horizontal and vertical scale units
• Grid—Properties related to the grid that is displayed on either side of the runway in the terrain and obstacle element
• OIS—Contains a property related to the symbol for the obstruction identification surface (OIS)
• Surface—Properties related to the appearance of the surface
• Runway—Properties related to the runway symbol
• Obstacle—Properties related to the appearance of penetrating obstacles and the symbols used

When you modify a symbol that is part of the element, there is a separate dialog box that appears so you can customize the color, size, and other aspects of the symbol's style. Due to the size of the element, it is not possible to preview it on the Terrain and Obstacle Profile dialog box.
