I think that if you look at the degree course being offered now, they come in various flavours (aeronautical engineering, aerospace engineering, aviation engineering, aeronautics and astronautics...) usually available in both BEng (only good for IEng nowadays unless you top up with an MSc) and MEng (good for CEng).
I do a bit of teaching on three courses at two universities; two are called "Aerospace Engineering", the third is called "Aviation Engineering"; all come in MEng, and two (one of each flavour) offer BEng also. All of them are accredited by the RAeS.
The non-accreditable courses tend to be called things like "aviation studies" or "aeronautical science".
