Roger that, I stand corrected (too used to the Yeovilton South AIAA where *most* traffic is sub-1000' level, even though it is in fact designated SFC-6000').
Agree totally on the RIS, though some places where you cannot get a RIS (Highlands of Scotland, scooting down the valleys- although not an AIAA it can surprise you to see a Tornado head on at 400 kts
) it is recommended to sqwark mode C...anything that helps really....
I wouldn't avoid an AIAA just becasue its there, but I would take all available precautions to stop myself becoming a statistic....
