FSX ILS Feather

I am designing a new airport using FSX Planner. I used the ILS tool to place it along the center of the runway on the head of the runway that has the ILS.

I noticed that the ILS feather (the long one) is placed where I put it or move it, that is along the runway centerline.

However, I see that when you do place an ILS feather, there is also another much smaller feather (isoceles triangle) situated somewhere back but with an offset to one side of the ILS feather you place.

This smaller trinagle is ALWAYS appearing when you drop a new ILS. So I wonder where will be the localizer signal? I am asking because I noticed that in one of the airports I have I was doing an automatic ILS approach (normally I do it manually) and the plane caught the glideslope but as it went down it became clear to me that it was going to land on the edge of the runway!

Do I need to move that smaller feather manually to align with the longer feather?

Generally I would expect the smaller 'feather' represents the glide slope. . The ILS localizer would usually be placed at the far end of the runway it serves. The Glide slope will be placed at the touch down point (off to one side of course :)) If this is the case with FSX Planner then you certainly would not want the GS placed with the localizer. This would make the touch down point off the far end of the runway.........
 
Great explanation Jon! that's something the FSX Planner developer failed to explain in the help file. Now I have a better idea. Haven't figured out how to design approaches yet but apparently nobody knows :)

Anyway, the ILS feather thing is finally cleared out thanks to you. Happy New Year 2013!

There is plenty of stuff around on designing Approaches. I would not know how to do it with FSX Planner. In ADE we have a graphical designer for approaches that should make it easier.
