SkyYacht, the subsidies in the US aren't as high as they seem- much of the ifrastructure is covered by levies on the industry itself, such as fuel taxes and surcharges on airline tickets. In Canada the air navigation system and airports are entirely user-pay and they manage to do it without nickel-and-diming the GA community. Forget those old "common good" bromides about making other people pay for your recreation- that kind of nonsense results in less money for aviation and more in the pockets of those civil servants who make a career out of shuffling the deck. From what I've seen in the threads about landing fees, the bottom line is that the airport managers in the UK don't have a clue how to run a business- a little creativity can go a long way. Kudos to the airport operator over there who discovered lower fees=higher volume. I hope for your sake that they've started a trend.
