Engine Shutdown Question...

[tgrayson]

Nobody has evidence, just opinion, nothing wrong with that.

Not a veiled insult at all, just an observation that you have an unsubstantiated opinion that is contrary to what is considered to be good operating practice by pilots of great experience.

Deakin has a great deal of knowledge in this area, a good bit of it due to his access to engine test data generated by George Braly of GAMI. He has also demonstrated a disciplined willingness to look at the data generated by his engine monitoring systems to identify and verify good engine operating practices.

Not everyone's opinion is equal and Deakin's, in this area, carries a good bit of weight. The burden of proof lies with those who hold different views.

I think the problem here is that you are all assuming that there is a "correct" answer here.

There isn't....there are only techniques.

Not entirely. There are at least two "correct" answers:

1) It doesn't harm the engine
2) And it can prevent fouling

Whether you choose to follow this procedure or not is a technique.

1) It doesn't harm the engine
2) And it can prevent fouling

3) flying around with fouled plugs can harm the engine.
4) "burning the plugs clean" while sometimes nessacery is not good for the engine.

Bringing up the RPM to 1800 on the ramp is a poor idea. And it's completely unnecessary to prevent fouling the plugs. Just lean the engine during taxi.

kinda late responding to this, but thats what we do when we are clear of the runway and doing our after landing checklist. although in the securing checklist it says to do it. and some student here do it.
