Hm, too little strong knowledge usually complicates things. It's a long road coming to understand why 330 STS says consider APU start and 320 does not.
2 suggestions:
A) FCTM purist would start before STS, as part of the reset/recovery procedure. This is the most logical moment in the task chain of handling the abnormals.
B) When reviewing the ELEC page of the affected systems.
Personally I think A) is correct while B) achieves the same quicker and with less effort. As long as we're on the same page, it makes no difference.
With the present and previous operator alike, choice B) is the agreed practice.
