I've been NATS qual'd since 1990. There's always the chance for exceptions, which is why we have human beings instead of silicon chips running the show.
Well we've been NAT'ing for about the same length of time then. Just to be clear I have absolutely no argument with that or you. The worry is this those who can't see that despite their QRH ultimately the golden rule in aviation is "don't crash"....(or at very least least don't hit me on the way down)
Rgds...may all your problems be small ones...
