tpe 05
It was originally built as a runway- 05L and 05R .It was stopped being used as a runway 20 years ago and only used as a taxyway from then on. We always used it as a taxyway. Obviously it is much wider than a taxyway and that is why sq lined up on it in LV conditions as it looks like a runway. And yes they were working on it as sq hit what ever was left there. I don't know what markings were left on it regards being 05R, possibly there were. Whatever was marked on it was removed at some point. On the airport chart it was 05R but not anymore. Anyway it hasn't been used as runway for a long time, it was used as a taxyway. If sq had a correct runway ident procedure in their SOPs then the accident may not have happenend.
