Group: Forum Members Posts: 31, Visits: 108	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 Tags Custom data ILS Private Airstrip

Group: Forum Members Posts: 31, Visits: 108	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 ?

You should gete a pretty good average position which will match what your GPS in the plane is getting. Ditch Google Maps for that and do it in the real world. -- Chris. P.S.: I am sure there are apps available which let you average a position over time and display it on a map.
