Arm out the window
Yep, the businesses cases differ. Totally bought and installed as part of a trade off for other funding. We got kinda screwed. The original capital asset costs pale into insignificance when you consider long term maintenece and replacement costs. The fact that they are radiating all the time doesn't really mean they are free. You do want your ILS to be maintained so that it works in anger, that costs about $67000pa. If you need it to get in in IMC, its free, if you shoot a practice for currency in VMC, it's not, you pay for its availability until such time as you need it in anger. Yes a local training organisation uses it heavily but they pay the same as everyone else and don't have any priority in the queue so that point is moot. The current charges cover the maint ok but thats all. We would love for AA to install the next one and take it over but we are not holding our breath. One other private ILS I can name has no maint costs associated because of where it is. Luck of the draw.
