Editing ILSes with NavEditor
Required programs:
To start, follow the setup section of this tutorial then install NavEditor from the link above.
NavEditor automates much of the editing process by pulling data from the Airports Repository, so we need to show it where that is. Open NavEditor and select Airports Folder. Then, navigate to and select the folder the airports repository is located in. Once this is done, NavEditor will index all the airports in that repository, which takes some time.
Once that's done, click on Navigation Folder, and do the same for the Navigation Repository. This won't take long.
NavEditor is, at the time of writing, only capable of editing ILSes - not adding or removing them. First, choose an ILS that needs editing and open an issue for it. Then, type the ICAO code into NavEditor and choose the approach.
Next, edit the details shown. In this example, I'll be editing YSSY Runway 16L.
Even if all the details appear to be correct, click save as this will load the relevant information from the Airport File as well.
Now, go back into GitHub desktop, enter the ICAO Code in the summary, then commit your changes and push using the sync button. Then, open a Pull Request on GitHub to have your changes merged into the main repository.
