And it will only get worse. Since user pays was introduced the decline in activity in GA especially has seen aircraft sold off and/or relocated to non controlled airports around the major cities. Then revenue drops and staff cuts are made plus charges increased. This in turn makes more aircraft be sold off/relocate etc,and around we go again. If it wasn't for the college at Parafield the tower would be closed long ago. More staff cuts etc. Simular story around the country I bet.However ASA doesn't help themselves either. Years past GA was considered their bread and butter with airlines the cream. Today GA is encouraged to stay away from CTA and ordered to put a full plan in for a minor track through airspace not even landing inside it, with regular long delays expected. So what does GA do? They stay away so less revenue,staff cuts etc and around the parcel goes again.
