HL Deb 16 September 2004 vol 664 cc207-8WA
Lord Rotherwick

asked Her Majesty's Government:

When the Civil Aviation Authority will introduce global positioning system overlays on instrument approach plates. [HL4148]

Lord Davies of Oldham

The UK Civil Aviation Authority currently has no plans to develop global positioning system (GPS) overlays for current instrument approach plates in an attempt to exactly replicate existing flight profiles based on terrestrial navigation systems. Once procedures have been developed that safely permit approaches using data from global navigation satellite system (GNSS) sources, new procedures will be designed to ensure that the appropriate design requirements are incorporated.

No such procedures currently exist in the UK.
