Just now at YSSY, I announced take off from 07 on unicom, since Tower was inactive.
When I was airborne Tower became active (Capt Bill) and stated I was in an active airspace and should have waited for clearance before taking off.
This is weird!
Can’t ATC, when becoming active, see what’s been communicated earlier?
Can’t ATC see that when an aircraft is getting airborne at the exact moment he takes control of Tower, that that specific take off was not under his control?
It seems unfair to be spoken to like that when I didn’t do anything wrong.
Can someone clear this up for me?
