Yes and the other "hairy practice" was one that I was taught early on in my training that the JPI put to bed very quickly....
That of opening the cowl flaps just before touch down "in case you need to do a go around"
The JPI showed that to be pretty damaging to big bore engines like IO-520's etc. The cooling gradient was quite scary and now if I HAVE to go around, I'll open the cowl flaps once the aircraft is established in the climb. Again, the JPI shows that this is benign to the engine as opposed to the cooling shock of opening the cowl flaps in the late final.
The cool down period on fixed wing turbos has long been contentious and I've NEVER understood the justification for it.
Helicopters are different matter where high power settings are used for the hover to landing...but FW ???
