Hi 
I wonder if you can help me, I am trying to set up a private airstrip in the custom data of SkyDemon. Its two runways that I have copied the coordinates from google maps and pasted them into the runways editor under position for each end of the runway. I have also calculated the displacement threshold for each end but the ILS function is not working out very accurately . Does the ILS work from the calculated coordinates of the runway or the identifier. I need to do some tweaking but not sure which figures to adjust.
Kind regards
Brinsley
 

The ILS feature takes you to the threshold, so any displacement is irrelevant as (in SkyDemon) the displacement is the bit sticking out behind the threshold. The coordinates you have specified should be for the threshold.

Thanks for that Tim....taken on board about the threshold and displacement......so if the ILS tacking to the airfield is off by a  few degrees to the right when i'm tracking its centreline visually, would you assume  the coordinates I have got from google maps are slightly out ?

That would be my assumption without having any of the actual data to hand.

Good idea.....I'll give that a try !!
