From the Eagle thread... Speed and Altitude

[kiloalpha]

So this is some interesting reading... er, discussion about the 10k ft rule and 250kt.

People state that the dotted line at 10,000ft means you can go as fast as you want, even in Class Bravo airspace. But, for VFR purposes, you need at least 5 miles vis (and 1-1-1) above 10k just for that reason (going fast.) But in Class Bravo you need at least 3 miles and (Clear of clouds)...

So what is it really?

:dunno:

its 3 CoC in bravo because everyone should, in theory, should be in radar/radio contact. in class E above 10k theres no requirement to talk to anybody. So, you can go fast, but you need to see further.
