If you take the time to read and understand it's really easy.
Thank you for your comments. Of course it's easy, those that said it's not, didn't took enough time to fully understand how the editor works.
Of course, if you want to do a PERFECT job, it takes time. But for a quick SODE replacement, it shouldn't take more than a few minutes per airport, and you do it only once, then it's saved, and you'll still have a more functional scenery than you had before.
