delay
Certainly it was bad phraseology that caused the problem...With a/c already on RWY, (making a backtrack) there are no many options what to do with arriving traffic, though. As a TWR controller all you can do is hope that dep. will start it's roll in reasonable time.
The question is whether controllers in LZ count dep a/c in sequence.
My question is - how do controllers in european countries put sequence numbers...do they ever say to No3 - "you're now No2, ....now you're No1,...", etc.?
