SatItIsntSo,
Why not look at when the screens are or could be switched on. You may find that you could turn them on sooner so that whilst you are completing other turns they are warming up.
I have just written our S76C++ normal checklist and moved things around to make it flow better and to use the time more efficiently (with due regard to the safe and correct order of switch on of course).
It's not costing me money to delay the take-off but it can annoy the Boss.
