Wake Turbulence - Interpretation

Interpretation - what a can of worms that word can mean with regulations.

I have my own (strong) view on this - but in the interests of seeing others, please tell me what you think in the following scenario (only one of a few!).

Background - Australian Airspace (pretty much ICAO standard v.v. wake turbs) - Assume IMC (no vis sighting possible)

Like to know pilot as well as ATC's interpretations.

PLAN VIEW

[b][A] ------------------------->B763 3000FT HDG090

[C] C402 2000FT HDG360


Excuse the crude graphics.

We are using 6NM Sep Light (C402) with Heavy (B763).

At what point can B763 descend? Assume radar separation of 3NM?

a. When B763 is 3nm from C402 and 6nm from A.
b. When B763 is 3nm from C402 and 3nm from A.
c. When B763 is 3nm from C402 and 0.5 nm from A.
d. When B763 is 6nm from C402.
e. Other.
