'morno' spot on........."It is NOT up to VFR pilots to learn all about instrument approaches, or study every possible approach to any aerodrome they may visit.
It is however, up to IFR pilots, to use one method that everyone can understand. The "KISS" principle (Keep It Simple Stupid) comes in here".
IFR drivers have been thru the VFR school of training so out got know better, VFR are not expected to know anythig about IFR rules or regs, although it is in their best interest to perhaps improve their knowledge of such things.
Remember at the end of the day ALL pilots flying the IFR should allow for the lowest std of VFR pilots abilities & hence need to act/talk/decison make accordingly when in places where these as mentioned conditions can exist. Rules are fine but it can be those very same rules than can kill us!
