Thanks AR
Very interesting.
It would be ironic if the "instruction" turned a benign situation into a close call. (I've been surprised sometimes when ATC has told heavy metal that they might get a TCAS RA from me, even though they are what seems to me to be a looooong way away. e.g. me late downwind and the heavy metal on long final. Someone very close to me who flies heavy metal says the SOP is to disable functions of the TCAS when operating into various busy airports OS, due to the volume of nearby traffic. But maybe I misunderstood the detail.)
Serious question for the heavy metal drivers: So you're on base at YMIA and a GA guy doing a straight in approach to the same runway is a collision risk but isn't on frequency or ignores the "instruction". What's the plan? I assume that because this is an obvious risk (or is it "threat" these days?) there's a pre-briefed plan.
(I know what you're likely to after you land, but what's the in-air plan?)
