Another thing required with the new ammendments is to call maintaining altitude if not radar identified.
I remember when I first started instructing IFR I was hounded by the seniors at the time as to why I didn't teach things such as request traffic, code etc.
As I moved onto charter conducting multiple IFR sectors I learnt by experience that I didn't have to call ABC TOD request traffic then make yet another call telling them that I'm leaving....these days it's just ABC leaving altitude and I know I'll get traffic...plus you should have a good idea of who's around anyway with situational awareness.
The point is that the students i taught will do the request this and that and it is because I didn't know any better but with some experience I hope they'll know better.
