Creampuff please read all the responses and disregard the angry comments made. Just read the facts and the questions posed. VoR is saying that E airspace is a perfectly fine class of airspace. Yet not that long ago they were making comments about the difficulty of seeing and avoiding unalerted VFR traffic for RPT jets. Now how does anyone suppose a non-communicating, no flight plan VFR in non-radar airspace is ever going to be anything other than unalerted traffic for the RPT aircraft. What, is the IFR psychic and thus going to sense the aircrafts presence. VoR also went to great lengths to point out that airspace should never be designed with TCAS as a mitigating factor in the safety of said airspace. Non-Radar E airspace as pointed out above has 2 levels of defence, first visual acquisition of a target the IFR doesn't even know is or isn't there, and then TCAS. How can anyone ever consider that to be safe??? And while people are saying safety is a relative term, in this case its bloody clear cut, if you are relying on only one safeguard before relying on TCAS to save the day, then thats dangerous, no matter what happens or doesn't happen in the states.
