Dick, I'm just a controller with zero organisational influence. You could convince me we could send a wombat to the moon without raising AsA costs and I could wax lyrical at work, but it wouldn't help get the wombat launched.
By current resources I don't mean money. Controllers don't grow on tress - we need training which takes time and additional training resources. Sectors need redesigning, which again takes resources. You can throw all the money you want at it but you won't find the resources necessary to achieve the changes off the street.
As mentioned elsewhere even if you convince CASA we no longer need an approach endorsement to provide an approach service we still need the training to allow us to do it. More resources.
