I guess the issue(s) come down to:
Who controls/owns the air above an airfield?
What rights does a PIC have to navigate where /whenever - subject to existing Federal airspace restrictions.?
Should it become the "norm" for airfield owners to charge for use of the airspace above - at what point should this charge be levied (height above, distance from, services (if any) provided)?
What might be the implications eg avoidance leading to fuel exhaustion/forced landing, would declarde emergencies and emergency response aircraft be fee free ?
Landing fees vary, $0-20 (probably more)/landing for an RAA level aircraft - how can this be justified (greed?)?
I feel that Australian pilots should remember, almost all airfields were owned by the Federal Government / US!. Due to the adoption of the now discredited Economic Rationalism /User Pays economic model, our short sighted Gov disposed of (sold & gifted) most of the airfields. Much like roads, rail, ports, electrical & water supply that are part of our essential (publicly owned) infrastructure, airfields that were completely open, are now restricted and/or being developed for non aviation purposes. Like most of the other public asset, that have been disposed of, this is an evolving disaster that we the people have allowed to happen (she'll - be right - mate). Public infrastructure/services underpins the economic & social wellbeing of a country, we are the poorer/disadvantaged for the loss of such.π
