Over + Out I told you where I work, so guesswork doesn't come into it. It most definately is a busy environment, and Spuds already said what I wanted to say. I ask you again, what do you expect from a pilot....1000, 2000, 3000fpm?? What will a pilot give you? Are they the same? What if they're not? If it leads to a loss of separation, will you say "well I told him to expedite"? It simply is not a clearance upon which separation can be assured, due to the inherent lack of definition, and the very nature of this thread, the fact that a pilot quite understandably felt the need to ask the original question, shows that to be the case.
