So if a major part of the problem is that the per-plane expense gets to high why not deploy some technology at the airport itself? Would some system of text boards next to the various junctions directing planes by their tail-number (or whatever the common id they use is)? I'm thinking boards that reinforce the existing system, saying things like "XXXXX: Hold here" and "XXXXX: Left on November" with a zonking great arrow pointing down November. Of course when you're done you have only done that airport, but at least you don't let the old skills rust. You would reinforce the existing comms, and if the system was out, or a pilot arrived an airport that didn't do it they ought to still know what to do.
