Otto Throttle,
I'm replying as a "plonker pilot". The company I work for has S.O.P's. You may be aware of these.
I have a great admiration and respect for our engineers, a fanatastic bunch of men and women, who, also understand S.O.P's.
When our procedures call for the de-powering of the aeroplane, we do so. The before said engineers, who understand our procedures, when required, ask if we could not do so on this occasion so as to facilitate certain other requirements...
