Not sure what aircraft you designing the SOP's for. But I fly the A319 and A340 and I am peeved with the prelim-cockpit and cokpit setup according to our SOP's ..
There are only a few switches that need to be pushed during the cockpit setup, the rest calls for just checking. But our SOP has this very complicated and strange way of checking each switch. On the line i find it easier just to start from left to right and switch on or off whatever needs to be prior to start. But in the simulator some instructors become pedantic about the exact flow....which makes no sense at all...I mean to verbalise each check such as ... "o.k. landing gear lever is down, thrust levers are at idle...etc" we wasted about 1 hour going through things like that. The airbus was designed to check " all white lights out" so why complicate matters.
This is in South Africa by the way.
