Dick,
After reading the spiel by your lacky, you now have only one option: do a complete design safety case on commercial operations at uncontrolled airports to sort out the truth once and for all. I don't give a stuff how long it takes. If it "delays implementation", too bad.
Reference the "lack of inclusion of ground collisions" and how that has alledgedly contributed to the invalidity of the BME DAS, doesn't your expert appreciate that ANY type of third party, starting at a CAGRS, would significantly increase the safety of commercial operations by maintaining a visual lookout from his "tower", thereby further strenthening the conclusions of the DAS? This one point severely calls into question the credibility of Dr Roberts. Perhaps that is the problem: "experts" such as him (and yourself?), commenting on things about which they know little or nothing.
mjbow2,
Could you please explain how much of the Class G airspace you claim goes up to FL145 is used by commercial operations? You may also like to mention how much FL145 Class G is filled up with the Rocky and other mountain ranges. Der.
