Are you likely to conflict with other traffic whilst undertaking an ILS PPL or IR?
"G-ABCD turn left heading xxx deg to intercept the ILS rwy xx report established"
"G-ABCD contact tower on 123.45"
"G-ABCD continue approach"
"G-ABCD cleared to land rwy xx"
All these are clearances of such by ATC, and surely they would only vector you to the ILS if it was safe to do so, they wouldnt say "G-ABCD cleared to the ILS rwy xx but watch out for that 737 that could be on your left same level"
Just a thought, pick holes in it at your will, end of the day all these discussions will make us better and more knowledgable pilots, if we listen to each other's points of view
Happy Landings
