However, to propose the complete removal of NDBs from the UK at this time is felt premature as currently there are 116 NDB IAPs, which all IFR aircraft can utilise, as opposed to 8 RNAV approaches that a small percentage of aircraft can currently utilise.
Why on earth not simply authorize GPS overlay approaches, thus accommodating aircraft with both old and more modern avionics? This could be done quickly, unlike the glacial speed of the roll out of the pitiful number of available RNAV approaches.
