Hi, thanks for your contribution! Since you requested a review, I looked over your changes.
I don't know too much about aviation - are FBOs aircraft fuel stations, as in petrol? If so, looks like the tag to use would be aeroway=fuel: https://wiki.openstreetmap.org/wiki/Tag:aeroway%3Dfuel
I can add that if you want, just let me know.
Thanks again and welcome to OSM!
