Correct, but this is referring to the approach itself i.e. ILS, VOR, ADF etc etc. The initial question was how to get to the IAF.
I have a feeling that often there is a misunderstanding between the actual meaning of the ATC clearance, for example, "...you are cleared straight in ILS approach rwy 36" and the interpretation by us pilots. All it means is that you are cleared to execute a published approach, that is within 30 degrees of the intended landing runway.
