Ops is very relevant because it will all appear again in your company ops manual. Come 2020 we will have the new syllabuses in, stuff that myself and several colleagues spent several months in Cologne rewriting - a lot of stuff has gone but a lot of new stuff is in, covering just what you are mentioning (you can blame JAA for the original dog's breakfast). People on the EASA rulemaking task were all pilots, pretty much, or at least very experienced instructors. I couldn't quite get Microwave Landing Systems out, though - there are still two available for use around the world, though aerodrome reference codes for helicopters will have disappeared.
