Climb To
Bekolblockage,
Let me be blunt. I think you are a moron. Are you willing to be your life that no one will ever mistake Climb to 9000 with climb 29000? I am not.
You seem to be doing a good job of illustrating that "Rules are for the compliance of fools and the guidance of wise men"
The only way to avoid this error is to avoid using TO. It is superfulous.
There are many tired and non native English speakers flying around. Why does HK insist on continuing to use this flawed phrase? Me thinks you are the dope who insists on it's use by HK controllers.
