Each country's civil aviation authority determines whether to authorise GNSS approaches, for example this could be DGAC France, CAA UK, FAA USA.

The CAA UK has recently authorised non precision GNSS approaches.
Information on the UK requirements can be obtained from

http://www.caa.co.uk/docs/33/20070704ATS108.pdf

The document mentions "suitably equipped aircraft". This will normally mean that the aircraft is equipped with a Multi Mode Receiver (MMR) which will permit reception of GPS and interface into the aircraft's navigation system. Most new commercial aircraft are now equipped with MMR, including Airbus, Boeing and Embraer.

OACI/ICAO does not certify aircraft or GNSS approaches, it publishes the international requirements for them. Each ICAO Contracting State, for example France/UK/USA, then determines whether to accept the ICAO requirements and then publishes it's requirements via their civil aviation authority.

Having used an approved GPS in my private aircraft for the last ten years in the USA, and during that time having completed at least 100 GPS (only) let-down procedures, never once has the unit failed to operate as advertised...and with superb accuracy.

GPS....don't leave home without one (or two).

Hey 411a - how ever did you manage in the old Tristar then??:}:}

GPS approach is excellent - have done a fair few in the 'bus, much better in Africa, Asia etc where the ground based navaids have a habit of turning off at the most inopportune moment!! Obviously there are provisos and procedures to follow - at least in the air transport category.

Not some much the aircraft as the equipment fitted that will be approved for GPS Non Precision Approaches.

We install things like GNS430/530 etc in GA down in Bournemouth, UK and recently we have been able to add GPS NPA to the list of other IFR certifications (Like BRNAV enroute etc) that our installations include. For UK operations this CAA document might help:

www.caa.co.uk/docs/33/CAP773.pdf (http://www.caa.co.uk/docs/33/CAP773.pdf)

It lists the minimum requirements for the equipment, and the type of installations that can be certified. Aimed at the private / GA sector but might offer some info.
