My dear
SINGAPURCANAC you have absolutly no idea of what made me ask this question, but i'm also in a good mood today and I will tell you:
I was working departure (teminal) where we use 3nm/1000, and I was perfectly confortable with the situation when I handed off the 2 ac to the enroute. But on there side, the enroute was not confortable with that. They just asked me to make sure the lower one was clrd 1000' below the higher or 5 nm appart before handing them off. That's about it!
Thank you anyway for taking a little of your time to give precious advices!
Acoording to the answers I can assume that everybody understood my question...Maybe I didn't give enough details to fully get the situation.
So I was just asking if this concept of sep loss with ac always separated exists somewhere else than in Canada (which, bye the way, I just can't find in our AIP...
)
