FTDK,
The licensing of the aerodrome brings in a requirement to monitor the approaches ( used to be annually ) to ensure no one had built a comms tower or something smack in the middle of the approach and some degree of accurate initial reporting of the aerodrome location to surveying standards.
Want to talk about high precision approaches etc????
Who's going to be the first person to try the Lithgow approach in a fixed wing??????? hope it's a maule or super cub.
