Changing ADE to show a view of the airport at night.

Changing the altitude of a stock airport requires a bit of work.  Just changing the value in airport properties will not work.  This is because any altitude change must be read before the stock airport records.  This is the opposite of the usual order where the last loaded file is the one that counts.  So to change the altitude of a stock airport we need to create a small bgl file that loads before anything else.  This is often called a pre-load stub.  ADE can make this easy and will also update any airport elements that have altitudes that should be changed.

The display grid is now drawn based on a given spacing between lines.  The default is 500m (1500ft) however this can be set by the user.  The drawn grid is centered on the current airport reference point and extends 50km in each direction (100km x 100km).

ADE needs to know about library objects before it can place them in the display.  This tutorial shows how to add this information
