brain, you seem to be on a one man crusade against BRS. You ask if there is any superflous R/T in you transcript - as it is written down by your good self there is and it's akin to "where's our traffic" referred to in the original post on this thread.
Why did you introduce an unnecessary call at G2. I would refer you to my earlier post in this thread - controllers don't do things for no reason. And G2 is not there for no reason. I would hazard a guess that its proximity to the 09 glidepath means that it is there to protect the GP signal in certain circumstances like, oh, I don't know, maybe an aircraft is using the ILS. Maybe I'm wrong - but there will be a good reason why you were held there. And when you were able to continue to G1 I'm sure the controller wasted no time in clearing you to continue.
You want to know why you were told to hold short. It's because you were being given a departure clearance but you were not yet cleared to line-up. Maybe you understood this. Maybe you've never lined up on a runway without a clearance - but trust me, if you did, you wouldn't be the first.
Why don't you give BRS a break and try to understand why they do the things they do. Better still, though it pains me to say it, why don't you get on with flying your aeroplane and let the controllers do the stuff that they know about.
[Edited simply to say that Standard got there first - and hey, I was right about G2!]
