Adding Runways
This is an example of adding a model airfield runway.
In google maps, go to the runway you want to add. Use Measure distance tool and measure the distance down the center of the runway. Save this value for the distance (this one shows 418 feet)
Next shorten the line to exactly 1/2 the value, then right click the point and copy the coordinates. This is the midpoint and is used by the map (this one is 39.62696, -104.85306)
Also get the coordinates for the start and end points, these will be used to calculate the direction of the runway.
Next measure the width of the runway (this one is 51 feet)
Go to this website https://www.movable-type.co.uk/scripts/latlong.html and enter in the endpoint coordinates
It will give you the bearing of the runway (you can display the map to verify the coordinates are correct.
This direction is between 1 and 2 degrees, either value will work.
In the CLI enter the airport abbreviation and runway name (these are displayed in the G1000 display when selecting an ILS approach), lat, lon, direction , length, width, and letter if it's a parallel runway
>runway CHER 36 39.626957 -104.853056 1 418 51
After entering both runway, this is what you will see when you fly over it (actually being there or in the simulator)
Here are a few other runways
Rocky Mountain Metro airport (this is a real airport)
