I believe position fixing is on the PPL and the CPL syllabus.
Maybe its a new thing but it wasn't on my CPL syllabus at the FTO I taught at, to teach VOR and NDB tracking. NDB tracking is a rather large subject to teach and get students to grasp in a relatively short space of time.
I was once told by a veteran CPL instructor to go and teach the PPL syllabus but to a higher standard.
