If you think that E is a safety improvement over G for RPT jets then you must believe in Santa Claus too. No one on this forum has yet to come up with any real data to prove the claim that E is safer than G in this area.
With the amount of traffic mix involved, I can see a "Launceston" happening and hopefully only a near miss will occur. The whole context of having Safety Management Systems is blown out the window when the safety of 180 pax and crew is all down to TCAS!
