I use them on the odd occasion.
I call it an anticipative call...
eg. Mel Centre, VH-XXX is where-ever, request airways clearance direct Essendon, preferably 7,500ft.
VH-XXX you are now at 25 miles, begin descent. Roger, Centre, VH-XXX will begin descent at 10 miles.
It's a little like my intersexual departures.
Maintains is also valid. It's when you speak on behalf of you and your aircraft. All stations Avalon, VH-XXX, we are 5 miles out (even if you are single pilot), or VH-XXX turnS left base for 36.
You guyz have gotta do that engrish test some time soon.
