Thanks for your informative reply.
It seems there are some others that are simply there to snap at anything!
I for one didn't realise you couldn't see the 06 end and that you are not allowed to issue conditional line up clearances. That is a reply I can live with.
Not sure about the calibration at exactly that time, but I am sure it wasn't the ATCO's decision.
I look forward to the big tower's improvement!
