Please excuse my ignorance on aspects of this issue people, but I have a few questions. If there is an AWIS at the aerodrome does that give current wx? Is traffic passed via radio by other aircraft within 30nm? Apart from these two things it seems everything else a Unicom operator is allowed to do is related to logistics/ground support. Could someone please point out the safety advantages of a Unicom operator working within their guidelines? As opposed to listening to correct freq radio's and the AWIS. Is the reason CAGRO's are CAGRO's the lack of radar.
Is this about cost? It would seem if we were looking at safety I would have thought a tower would be best. What are the cost differences between the AFIS, tower and Unicom.
Sorry if I've drifted this a bit I'm just interested in the usefulness of someone who can't look out a window, listens to radios and reads wx. As opposed to a trained, competent CAGRO/tower.
