You're telling the controller what rules you're flying under.
Do you have a reference for that? Had a brief scan through 413 but couldn't easily put my finger on it.
I've always assumed that I'm giving the controller chappy (or chappess) the conditions I'm flying in - that way they have a better understanding of the help I need....
I was always taught it was a PACER call, being...
position
altitude
CONDITIONS estimate
request
I'm not saying you're wrong, just want to know if I am!
Cheers
