I am causing delay now?
I am well familiar with loco UK airports...never had any issue on my 'lenghy' costly line up method.
If im asked to expedite,i will...dont take me wrong...but a long line up followed by a stop and then a take off roll, i say N0.
Ill leave that to your superior UK captainship.
OH and i do this crazy stuff based on a UK caa issued ATPL...thats food for thought.
