and who actually pays for the application ??
Norwich Airport Ltd.
I think you mean it's us who pay - through the nose by the over-inflated landing fees (compare them with a regional airport in say France) and if you're a commercial pax by way of the passenger, airport development tax, sorry, fee.
Quote from the Airport website
Future investment that the ADF will support includes:
- Establishment of controlled airspace to enable more efficient management and routing of the increased level of flights
So next week the approach family will be donating £25 towards restricting my future flying around Norfolk.
