AIP already has info on avoiding published IAP and routes where possible.
I’m aware of this, from ENR 1.1, which is about ops in Class E:
3.2 VFR Flights in Class E Airspace
3.2.1 VFR flights entering Class E airspace do not require a clearance, but may receive a Surveillance Information Service (SIS), where available, on request (see GEN 3.3 section 3.3).
3.2.2 VFR flights entering and operating in Class E airspace should:
a. avoid published IFR routes, where possible;
b. monitor the appropriate Class E frequency and announce if in potential conflict; and
c. take appropriate action to avoid potential conflict.
3.2.3 Pilots of VFR flights should avoid IFR holding patterns.
Are you able to quote anything about avoiding IAP waypoints in G?
