The above cannot be done in the US. We can descend to the MEA (which
varies, ATC knows and will tell us), and if we are not in VFR
conditions, then we have to do an intrument approach. MEA's are higher
than 1000 AGL I can tell you that. MEA's are not published, but ATC has
a map of them.

MEA's are published. MVA's are not published. A minimum instrument
altitude is always going to be 1000 above the terrain.


Radar coverage madatory for IFR flight (with one
exception, Class G).

Absolutely INCORRECT. Radar coverage is not mandatory for flight
in controlled airspace. An IFR clearance is, but radar is not
necessary nor sufficient for a clearance.

I don't honestly know what the rules are for
descent in Class G with no radar and no IFR clearance

Same as for controlled airspace 91.175 makes no distiction.

?. I don't think
there are any. It doesn't happen much, almost all our IFR flight is
with radar coverage and ATC clearances etc.

Nonsense. Many airports with approaches exist outside of controlled
airspace.
