The reason for 9L being used was because there was a blanket ban placed on the aircraft taking off from ANY runway undergoing construction, post Gonesse. (I seem to remember that the restricion was placed due to crown life issues). Oh, and Brit312; I knew that this all happened long after you put your last HP valve switch to SHUT, that is why I made the coment.
And Dixi188 has kinda answered the trick part of this question too, regarding 10/28 Left & Right. (As well as the 'correct' cross runway QDMs). Nice one Dixi
Answers in total in a couple of days guys, and keep 'PM'ing away about this, I'm happy to carry on answering.
