Topdrop. You say it is a good idea.
Why then wouldn’t other countries take this “ good idea” and at a minimum recommend that VFR pilots in class E monitor and announce on ATC frequencies?
Could it be that it would turn ICAO class E into a bastardised form of ICAO class D?
And what is the ATC supposed to do when separating two IFR in E and a VFR pops up on frequency and commences to arrange separation with one or both of the IFR aircraft?
Do you still think it’s a good idea or haven’t you actually thought how it would work in practice?
