Just looking again at the first post, that AIC ref doesn't look right

This is the latest on the AIS website which laid the foundations for P-RNAV. I'm told the next step will widen the scope to CA beyond London late 2009/early 2010.
Also, I think the TGLs are to be included in EASA regulations; AMC 20-8 rings a bell.
Hope this helps
