The QR crew COULD NOT have calculated performance for T1 intersection take off. The EFB platform on board their aircraft would not LET them do it. Period.
It would say "No Intersection".
However it would quite definitely churn out figures for a #T1 departure. That is Temporary runway 09('Temporary' due earlier notams), but full length of runway 09.
They would therefore, at best, have performance figures for full length 09 and have taken off from T1 intersection, with full length assumed!
Having said that, we're they poorly informed of the phonetics of the EFB/OPT performance tool?
Would be my guess too.
