Oh my gosh - we are really getting into the small print now!
"Note 2: Aircraft receiving services from Air Traffic Control Units are expected to comply with clearances and instructions unless the pilot advises otherwise."
In Class G its a see and be seen environment. A larger aircraft does NOT have right of way whilst positioning outside controlled airspace, except in accordance with the rules of the air - whatever the aircraft size, weight, POB or name painted on the hull.
If I'm requesting a Flight Information Service, that is all I'm asking for, not to be given radar headings to give preference to a "home based" aircraft as if I'm under radar control inside Class A, especially to "avoid" an aircraft I've already seen and said I am well clear of.
A controller giving a FIS is only expected to pass traffic information to the pilot requesting the service, not to "take control" of it. Even under Radar Information, a controller shouldn't try to mandate one particular aircraft to give way to another. It's up to the pilot to take what action, if any, he thinks necessary under the rules of the air and common sense. Radar advisory can be offered or requested, in which case, the pilot should expect headings etc - that's what he is agreeing to. Everything else is by negotiation, hopefully to the mutual benefit and safety of all.
Most ATC personnel at the major airports certainly operate in this manner - but a few at some minor airfields don't. As well as the pilot who doesn't keep clear of CAS or make a radio call when prudent, it's this minority in ATC who make a rod for their own back, which impacts on everyone eventually.
BTW, I'm playing Devil's advocate here - I always do EXACTLY what a controller requests, as politely, accurately and as promptly as possible - even when it inconveniences me in Class G. Sometimes, by listening out, looking out, watching TCAS and building a big picture
before I make my request, I have already done what I can to make his, or her, life as easy as possible.
Never call 'em "Sir" though.
