The E is safer than G for a number of reasons.
In cloud you cannot use see and avoid. Or even use alerted see and avoid.
With E the only aircraft operating in IMC are fully separated by a third party using a recognised safe separation standard.
Also all VFR in E must have the minimum of a mode C transponder allowing for the extra safety backup of TCAS.
With G it’s up to the lowest common denominator to choose a separation “ standard “. Could be set by a 300 hr very inexperienced pilot.
There is no dual frequency problem in E . If cloud is at the minimum the IFR remains on the centre ATC frequency as VFR are not allowed in the airspace without a special VFR clearance from the centre.
When VMC exists IFR in E can use similar procedures that we now use in G. There is no less alerted see and avoid.
It is a very versatile and safe airspace. Remember what VOR stated years ago on this site. I will try and find the post.
Bloggs. Do you want me to donate to you the cost of an air ticket to the USA so you can find out the truth about E ?
