Ah, Yes......A User Fee
For many years now, YABA has been used for ILS training by a bunch of Perth based aircraft.
In recent times, as the Perth airspace became more congested, and the charges increased, we've seen a lot more ILS training down here.
The ILS does not belong to ASA. It belongs to the City of Albany who used a grant to purchase it, ($700k), and $300k to instal it. The cost of calibration and maintenance, (a contract with ASA), is around $180k annually.
As many see it, the owner has a right to impose 'user' charges for such an investment.
happy days,
