10W, I agree with the point made in your first post. However, the statistic you quoted would have been 100% if the necessary politics had been applied with the same vigour as for MNPS/RVSM. Beancounters will not pass out a single bean unless obliged to. The economic advantages of these things are rarely understood in those quarters, never mind safety. See you at the Gatbash!
M14P, well said.
lugnet, cute, but rather wide of the mark. Also not really adding anything constructive to the original post. But, hey! . . . This is PPRuNe - what the heck?
