Thanks Scott, I knew you wouldn't be far away.
So there you go. On the face of it Free Flight seems like a great idea, and a very attractive one for the bean counters (except when they have to PAY for the equipment). The practicalities are somewhat more difficult.
As I mentioned above, you need ALL operators to equip their aircraft and I don't think it's going to happen..... very soon. At the moment the current ATC system can handle everything from the lowest airways equipped PA28 to an all singing all dancing B777. Pretty impressive.
Still the future WILL happen. I wonder if we in ATC will have a say in it?
