This topic has popped up a few times over time here in other threads. Simply put as another has if yr a VFR pilot who doesn't really know where the certain waypoint is then ask tho inbound A/C. If that's not practicable due a busy time then YOU give or re-broadcast yr calls the usual way IE dist & bearing FM the AD keeping a sharp look-out for them (they are easier to spot than you in yr toy plane)& the so called profesional crew will figure out whether you are a threat to them. You will be surprised at how a 2 crew jet will soon start doing something about a possible conflict when they are not getting their own way. Another slight thing to remember here also is that in recent imes there has been a huge hiring of pilots meaning that a good proportion of the newbies in these jets came straighht from GA so it's very well possible that they (newbies) are playing the 'role' by impressing their masters & saying it the big Co's IFR way forgetting their GA IFR roots. Just an opinion but plausable I reckon in some cases.
Either way takes little by the jet crew to say the inbound tracking details in plain language for all to understand.
