AFAIK it's only an Australian thing. One excuse I heard was that it reduced torching, but the technique seems to be in favor of torching if you think about it, in any case the B model has a digital system, so much more refined and reactive to changes.
You really have no idea. Essentially everything you said is incorrect. It’s not an A model hangover. It’s not just Australian operators.
It’s in the AOM FFS. The manufacturer recommends motoring starts for all starts on the ground for both A and B models. You can’t turn the ignition on before condition lever to start for a motoring start, because not only is the aircraft not designed to do that, it damages the start relay in the PDU.
But what would SAAB know
