Where do you get a "lack of SOP" on the 737? It's just as standard as every other fleet. And if it's some kind of 737 issue, we shouldn't have had another airbus depart without any takeoff data set, or a valid TPS recently.

I'm with aa73, any lack of understanding of the TPS is a training issue.

Back to the question that started this whole circus, I'd say any time an airplane is "waiting for numbers", it's probably because they haven't received a load close out yet, not a TPS.
