Perhaps someone can tell me what the current charge is for adding and maintaining an RNAV approach to an airfield? I have been told anywhere from $20,000 to $80,000 to establish and I suspect the same again every few years to have the approaches re-surveyed. Also, to have an RNAV approach the airfield must be either registered or certified, both of which attract a cost. I personally think Councils should cover those costs as a benefit to rate payers and attracting business and tourism to their area. However, a privately owned airfield is a different story because they have to cover their costs or there will be no airfield. Please remember not every airfield is owned by a Council or the Government.
