"The OPT offered the crew only one option for Runway 09, which was ‘09#T1’
On the face of it a bizarre designation for full length when there is an intersection called T1!
I think there is quite a threat to operations world wide hidden in what you say there.
The way information is presented to us now days is different. We become more and more accepting of computer generated information as each year passes. A lot of that information is generated by people with computer skills, but no aviation experience.
Personally I feel like basic gross error checks and rules of thumb are becoming more and more important as I get older because of this very fact.
I think there were many contributing factors here but one of them was the use of #T1 on the OPT. One other glaring factor was the Captains choice to not actively investigate ambiguity ( re concerns from other crew members).
