Hi louis5227, welcome to OSM.

The work you put into the airport and its runways is quite impressive. Maybe you should think about another OSM editor as a tool and support. iD does not seem to be the best choice here, if you look at the edit history here in this area around the airport. 

Here you can find some good information about JOSM: https://wiki.openstreetmap.org/wiki/JOSM

Best regards.
