Just because the UK CAA (and some others) chooses to allow such IFR techniques does not mean that they are acceptable in other countries.
And I believe it's "Altitude Voice Alert Device" but who knows, acronyms have a habit of growing their own decode.

In the US radar approaches are approved on an operator by operator basis. The operator is issued OpSpecs (Operations Specifications) for this type approach. The issuance of these Oppecs require approved training programs and procedures. However, these days they are not used to the degree they used to be. GPS approaches are easily made to each platform. Many of the GOM pilots I have talked with still use the radar as a additional tool and backup.
