So the idea is to install radar that has coverage to the lower levels. That would probably require it be located at Ingham because of the shielding from the obviously close terrain. At what expense? All this for infrequent at best IFR arrivals?
CASAs "approach" to this sounds pretty reasonable and cost effective. If we attempted to follow your lead we would smother the place in radar controlled airspace that the industry can't afford, and force timid VFR pilots (and I am not saying all are scared of controlled airspace) to fly into adverse weather around high terrain.
Dick, I know you are well intentioned and you have a lot of experience compared with a lot of other private pilots. Why not use a little of your energy and resources in educating pilots that controlled airspace is not to be feared.
